mod_rayo: Translate XMPP messages to SIP messages

Call-bound XMPP messages are translated to SIP messages via
SWITCH_EVENT_SEND_MESSAGE in a similar manner to that described in
draft-ietf-stox-im-06. Messages with a type of "normal" are directed
to the caller. Other types receive a feature-not-implemented response
but it is envisaged that the "groupchat" type could be used to direct
the message to all joined parties.

Fix --disable-core-odbc-support

In commit ffc8e81b763c4e11e02309b99e2a4b4aa666e845, tc ensured that
configure would abort if libodbc was not found. However this resulted
in the library check being done twice, as well as rendering
--disable-core-odbc-support ineffective. If libodbc was found, it
would enable core ODBC support regardless. This fix ensures the check
is only done once or not at all if core ODBC support is explicitly
disabled.

Ensure we don't set HAVE_ODBC unless we really do
Improve configure ODBC handling
Fix ESL infinite loop on handle_recv() when errno is already set
system calls do not clear errno, just set it in case of failure, so we
gotta make sure the recv() syscall really failed by checking the return value
Fix configure ODBC logic

...and rewrite entire block for better clarity of purpose.

We might want to look more closely at the AX_LIB_ODBC macro as well.
