Introduce mod_avatar

Browse Source 
The purpose of the module is to cope with legacy and modern
XMPP clients posting avatars. It automatically converts vCard based
avatars (XEP-0153) to PEP based avatars (XEP-0084) and vice versa.
Also, the module supports convertation between avatar image formats on
the fly: this is controlled by `convert` option. For example, to
convert all avatars into PNG format, configure the module as:

mod_avatar:
  convert:
    default: png

In order to convert only `webp` format to `jpeg`, set the following:

mod_avatar:
  convert:
    webp: jpeg

Note: the module depends on mod_vcard, mod_vcard_xupdate and mod_pubsub.
Also, ejabberd should be built with --enable-graphics option.
