/** Class: Strophe.Builder
 *  XML DOM builder.
 *
 *  This object provides an interface similar to JQuery but for building
 *  DOM elements easily and rapidly.  All the functions except for toString()
 *  and tree() return the object, so calls can be chained.  Here's an
 *  example using the $iq() builder helper.
 *  > $iq({to: 'you', from: 'me', type: 'get', id: '1'})
 *  >     .c('query', {xmlns: 'strophe:example'})
 *  >     .c('example')
 *  >     .toString()
 *  The above generates this XML fragment
 *  > <iq to='you' from='me' type='get' id='1'>
 *  >   <query xmlns='strophe:example'>
 *  >     <example/>
 *  >   </query>
 *  > </iq>
 *  The corresponding DOM manipulations to get a similar fragment would be
 *  a lot more tedious and probably involve several helper variables.
 *
 *  Since adding children makes new operations operate on the child, up()
 *  is provided to traverse up the tree.  To add two children, do
 *  > builder.c('child1', ...).up().c('child2', ...)
 *  The next operation on the Builder will be relative to the second child.

 *  finished.
 *
 *  To send data to the connection, use send().
 */

/** Constructor: Strophe.Connection
 *  Create and initialize a Strophe.Connection object.
 *
 *  The transport-protocol for this connection will be chosen automatically
 *  based on the given service parameter. URLs starting with "ws://" or
 *  "wss://" will use WebSockets, URLs starting with "http://", "https://"
 *  or without a protocol will use BOSH.
 *
 *  To make Strophe connect to the current host you can leave out the protocol
 *  and host part and just pass the path, e.g.
 *
 *  > var conn = new Strophe.Connection("/http-bind/");
 *
 *  Options common to both Websocket and BOSH:
 *  ------------------------------------------
 *
 *  The "cookies" option allows you to pass in cookies to be added to the
 *  document. These cookies will then be included in the BOSH XMLHttpRequest
 *  or in the websocket connection.
 *
 *  The passed in value must be a map of cookie names and string values:
 *
 * { "myCookie": {
 *      "value": "1234",
 *      "domain": ".example.org",
 *      "path": "/",
 *      "expires": expirationDate
 *      }
 *  }
 *
 *  Note that cookies can't be set in this way for other domains (i.e. cross-domain).
 *  Those cookies need to be set under those domains, for example they can be
 *  set server-side by making a XHR call to that domain to ask it to set any
 *  necessary cookies.
 *
 *  WebSocket options:
 *  ------------------
 *
 *  If you want to connect to the current host with a WebSocket connection you
 *  can tell Strophe to use WebSockets through a "protocol" attribute in the
 *  optional options parameter. Valid values are "ws" for WebSocket and "wss"
 *  for Secure WebSocket.
 *  So to connect to "wss://CURRENT_HOSTNAME/xmpp-websocket" you would call
 *
 *  > var conn = new Strophe.Connection("/xmpp-websocket/", {protocol: "wss"});
 *
 *  Note that relative URLs _NOT_ starting with a "/" will also include the path
 *  of the current site.
 *
 *  Also because downgrading security is not permitted by browsers, when using
 *  relative URLs both BOSH and WebSocket connections will use their secure
 *  variants if the current connection to the site is also secure (https).
 *
 *  BOSH options:
 *  -------------
 *
 *  By adding "sync" to the options, you can control if requests will
 *  be made synchronously or not. The default behaviour is asynchronous.
 *  If you want to make requests synchronous, make "sync" evaluate to true:
 *  > var conn = new Strophe.Connection("/http-bind/", {sync: true});
 *
 *  You can also toggle this on an already established connection:
 *  > conn.options.sync = true;
 *
 *  The "customHeaders" option can be used to provide custom HTTP headers to be
 *  included in the XMLHttpRequests made.
 *
 *  The "keepalive" option can be used to instruct Strophe to maintain the
 *  current BOSH session across interruptions such as webpage reloads.
 *
 *  It will do this by caching the sessions tokens in sessionStorage, and when
 *  "restore" is called it will check whether there are cached tokens with
 *  which it can resume an existing session.
 *
 *  The "withCredentials" option should receive a Boolean value and is used to
 *  indicate wether cookies should be included in ajax requests (by default
 *  they're not).
 *  Set this value to true if you are connecting to a BOSH service
 *  and for some reason need to send cookies to it.
 *  In order for this to work cross-domain, the server must also enable
 *  credentials by setting the Access-Control-Allow-Credentials response header
 *  to "true". For most usecases however this setting should be false (which
 *  is the default).
 *  Additionally, when using Access-Control-Allow-Credentials, the
 *  Access-Control-Allow-Origin header can't be set to the wildcard "*", but
 *  instead must be restricted to actual domains.
 *
 *  The "contentType" option can be set to change the default Content-Type
 *  of "text/xml; charset=utf-8", which can be useful to reduce the amount of
 *  CORS preflight requests that are sent to the server.
 *
 *  Parameters:
 *    (String) service - The BOSH or WebSocket service URL.
 *    (Object) options - A hash of configuration options
 *
 *  Returns:
 *    A new Strophe.Connection object.

     *  The Parameters _wait_, _hold_ and _route_ are optional and only relevant

     *  of the optional parameters.
     *
     *  Parameters:

     *    (String) pass - The user's password.
     *    (Function) callback - The connect callback function.
     *    (Integer) wait - The optional HTTPBIND wait value.  This is the
     *      time the server will wait before returning an empty result for
     *      a request.  The default setting of 60 seconds is recommended.
     *    (Integer) hold - The optional HTTPBIND hold value.  This is the
     *      number of connections the server will hold at one time.  This
     *      should almost always be set to 1 (the default).
     *    (String) route - The optional route value.
     *    (String) authcid - The optional alternative authentication identity
     *      (username) if intending to impersonate another user.
     *      When using the SASL-EXTERNAL authentication mechanism, for example
     *      with client certificates, then the authcid value is used to
     *      determine whether an authorization JID (authzid) should be sent to
     *      the server. The authzid should not be sent to the server if the
     *      authzid and authcid are the same. So to prevent it from being sent
     *      (for example when the JID is already contained in the client

     *  As a convenience, the ns parameters applies to the top level element

     *  The options argument contains handler matching flags that affect how

     *  Parameters:

     *    (String) ns - The namespace to match.
     *    (String) name - The stanza name to match.

  // UI as a **View** allows you to define your DOM events declaratively, without
  // having to worry about render order ... and makes it easy for the view to
  // react to specific changes in the state of your models.

-----------
A gettext compatible i18n library for modern JavaScript Applications

Dojo CLA for contributions

Jed offers the entire applicable GNU gettext spec'd set of
functions, but also offers some nicer wrappers around them.
The api for gettext was written for a language with no function
overloading, so Jed allows a little more of that.

Many thanks to Joshua I. Miller - unrtst@cpan.org - who wrote
gettext.js back in 2008. I was able to vet a lot of my ideas
against his. I also made sure Jed passed against his tests
in order to offer easy upgrades -- jsgettext.berlios.de

  // Big Integer Library v. 5.5
  // Created 2000, last modified 2013
  // Leemon Baird
  // www.leemon.com
  //
  // Version history:
  // v 5.5  17 Mar 2013
  //   - two lines of a form like "if (x<0) x+=n" had the "if" changed to "while" to
  //     handle the case when x<-n. (Thanks to James Ansell for finding that bug)
  // v 5.4  3 Oct 2009
  //   - added "var i" to greaterShift() so i is not global. (Thanks to Péter Szabó for finding that bug)
  //
  // v 5.3  21 Sep 2009
  //   - added randProbPrime(k) for probable primes
  //   - unrolled loop in mont_ (slightly faster)
  //   - millerRabin now takes a bigInt parameter rather than an int
  //
  // v 5.2  15 Sep 2009
  //   - fixed capitalization in call to int2bigInt in randBigInt
  //     (thanks to Emili Evripidou, Reinhold Behringer, and Samuel Macaleese for finding that bug)
  //
  // v 5.1  8 Oct 2007 
  //   - renamed inverseModInt_ to inverseModInt since it doesn't change its parameters
  //   - added functions GCD and randBigInt, which call GCD_ and randBigInt_
  //   - fixed a bug found by Rob Visser (see comment with his name below)
  //   - improved comments
  //
  // This file is public domain.   You can use it for any purpose without restriction.
  // I do not guarantee that it is correct, so use it at your own risk.  If you use 
  // it for something interesting, I'd appreciate hearing about it.  If you find 
  // any bugs or make any improvements, I'd appreciate hearing about those too.
  // It would also be nice if my name and URL were left in the comments.  But none 
  // of that is required.
  //
  // This code defines a bigInt library for arbitrary-precision integers.
  // A bigInt is an array of integers storing the value in chunks of bpe bits, 
  // little endian (buff[0] is the least significant word).
  // Negative bigInts are stored two's complement.  Almost all the functions treat
  // bigInts as nonnegative.  The few that view them as two's complement say so
  // in their comments.  Some functions assume their parameters have at least one 
  // leading zero element. Functions with an underscore at the end of the name put
  // their answer into one of the arrays passed in, and have unpredictable behavior 
  // in case of overflow, so the caller must make sure the arrays are big enough to 
  // hold the answer.  But the average user should never have to call any of the 
  // underscored functions.  Each important underscored function has a wrapper function 
  // of the same name without the underscore that takes care of the details for you.  
  // For each underscored function where a parameter is modified, that same variable 
  // must not be used as another argument too.  So, you cannot square x by doing 
  // multMod_(x,x,n).  You must use squareMod_(x,n) instead, or do y=dup(x); multMod_(x,y,n).
  // Or simply use the multMod(x,x,n) function without the underscore, where
  // such issues never arise, because non-underscored functions never change
  // their parameters; they always allocate new memory for the answer that is returned.
  //
  // These functions are designed to avoid frequent dynamic memory allocation in the inner loop.
  // For most functions, if it needs a BigInt as a local variable it will actually use
  // a global, and will only allocate to it only when it's not the right size.  This ensures
  // that when a function is called repeatedly with same-sized parameters, it only allocates
  // memory on the first call.
  //
  // Note that for cryptographic purposes, the calls to Math.random() must 
  // be replaced with calls to a better pseudorandom number generator.
  //
  // In the following, "bigInt" means a bigInt with at least one leading zero element,
  // and "integer" means a nonnegative integer less than radix.  In some cases, integer 
  // can be negative.  Negative bigInts are 2s complement.
  // 
  // The following functions do not modify their inputs.
  // Those returning a bigInt, string, or Array will dynamically allocate memory for that value.
  // Those returning a boolean will return the integer 0 (false) or 1 (true).
  // Those returning boolean or int will not allocate memory except possibly on the first 
  // time they're called with a given parameter size.

  // The following functions are based on algorithms from the _Handbook of Applied Cryptography_
  //    powMod_()           = algorithm 14.94, Montgomery exponentiation
  //    eGCD_,inverseMod_() = algorithm 14.61, Binary extended GCD_
  //    GCD_()              = algorothm 14.57, Lehmer's algorithm
  //    mont_()             = algorithm 14.36, Montgomery multiplication
  //    divide_()           = algorithm 14.20  Multiple-precision division
  //    squareMod_()        = algorithm 14.16  Multiple-precision squaring
  //    randTruePrime_()    = algorithm  4.62, Maurer's algorithm
  //    millerRabin()       = algorithm  4.24, Miller-Rabin algorithm
  //
  // Profiling shows:
  //     randTruePrime_() spends:
  //         10% of its time in calls to powMod_()
  //         85% of its time in calls to millerRabin()
  //     millerRabin() spends:
  //         99% of its time in calls to powMod_()   (always with a base of 2)
  //     powMod_() spends:
  //         94% of its time in calls to mont_()  (almost always with x==y)
  //
  // This suggests there are several ways to speed up this library slightly:
  //     - convert powMod_ to use a Montgomery form of k-ary window (or maybe a Montgomery form of sliding window)
  //         -- this should especially focus on being fast when raising 2 to a power mod n
  //     - convert randTruePrime_() to use a minimum r of 1/3 instead of 1/2 with the appropriate change to the test
  //     - tune the parameters in randTruePrime_(), including c, m, and recLimit
  //     - speed up the single loop in mont_() that takes 95% of the runtime, perhaps by reducing checking
  //       within the loop when all the parameters are the same length.
  //
  // There are several ideas that look like they wouldn't help much at all:
  //     - replacing trial division in randTruePrime_() with a sieve (that speeds up something taking almost no time anyway)
  //     - increase bpe from 15 to 30 (that would help if we had a 32*32->64 multiplier, but not with JavaScript's 32*32->32)
  //     - speeding up mont_(x,y,n,np) when x==y by doing a non-modular, non-Montgomery square
  //       followed by a Montgomery reduction.  The intermediate answer will be twice as long as x, so that
  //       method would be slower.  This is unfortunate because the code currently spends almost all of its time
  //       doing mont_(x,x,...), both for randTruePrime_() and powMod_().  A faster method for Montgomery squaring
  //       would have a large impact on the speed of randTruePrime_() and powMod_().  HAC has a couple of poorly-worded
  //       sentences that seem to imply it's faster to do a non-modular square followed by a single
  //       Montgomery reduction, but that's obviously wrong.
