o Change the usage of #state.lang somewhat.
o Fix value of DefaultLang: it doesn't contain the whole serialized
attribute.
o Use exmpp_jid:make_bare_jid/2 more.
I started to work on the second half of the module and discovered
several annoying things:
o JID are represented in two forms: the #jid record and the
{N, D, R} tuple.
o Sometimes, #xmlelement may contain non-#xml* tuples in their
children. This is the case for some <presence/> stanzas. Their
children are used to pass random data.
I'm less and less convicted that ejabberd_c2s can be fully converted
without starting to work on other modules.
