* Adds identify, transport, and registration support to the PJSIP CLI.

* Creates three additional callbacks, one for an iterator, one for a
comparator, and one for a container.  This eliminates the link dependency
from higher level modules to lower level ones.

* Eliminates duplicate sorting in PJSIP CLI commands.

* Cleans up PJSIP CLI output formatting.

* Pushes CLI command registration down to the implementing source file.

* Adds several ast_sip_destroy_sorcery functions to complement existing
ast_sip_sorcery_initialize functions.  The destroy functions unregister
PJSIP CLI commands and PJSIP CLI formatters.

Added a "debug" configuration option for res_pjsip that when set to "yes"
enables SIP messages to be logged.  It is specified under the "system" type.
Also added an alembic script to add the option to realtime.

Registering yourself with the Asterisk core is the nice thing to do, even
when you're a logging module.

This patch makes the res_pjsip_logger do a few things... First, it
will be built and installed by default now, so end users won't need
to enable it in menuselect. Second, while it is loaded, it no longer
will immediately issue log messages. Upon loading, it is in the
disabled state and must be turned on with the new CLI command. The
CLI command 'pjsip set logger <on/off/host> has been added and can be
used to do the following:
pjsip set logger on:
    Enables logger for all PJSIP traffic
pjsip set logger off:
    Disables logger for all PJSIP traffic
pjsip set logger host <host>:
    Enables logger for the specific host

This patch uses PJSIP's pj_log_set_log_func() to forward PJSIP's log
messages to Asterisk's logger. This is done in a new module:
res_pjsip_log_forwarder.so.

This patch sets defaultenabled on the existing res_pjsip_logger.so to
no, since logging every SIP packet seems a bit odd to do by default, and
is (hopefully) less necessary with regular PJSIP logging.

It also removes res_rtp_asterisk's disabling of PJSIP logging.

The general gist is to have a clear boundary between old SIP stuff
and new SIP stuff by having the word "SIP" for old stuff and "PJSIP"
for new stuff. Here's a brief rundown of the changes:

* The word "Gulp" in dialstrings, functions, and CLI commands is now
  "PJSIP"
* chan_gulp.c is now chan_pjsip.c
* Function names in chan_gulp.c that were "gulp_*" are now "chan_pjsip_*"
* All files that were "res_sip*" are now "res_pjsip*"
* The "res_sip" directory is now "res_pjsip"
* Files in the "res_pjsip" directory that began with "sip_*" are now "pjsip_*"
* The configuration file is now "pjsip.conf" instead of "res_sip.conf"
* The module info for all PJSIP-related files now uses "PJSIP" instead of "SIP"
* CLI and AMI commands created by Asterisk's PJSIP modules now have "pjsip" as
the starting word instead of "sip"

This patch updates the various res_sip modules with their proper menuselect
options and proper dependencies, such that Asterisk still has a snowball's
chance in hell of compiling without pjproject.

Much thanks to snuffy(-home|-work) for making everyone's life
easier with this patch.

The pimp_my_sip branch is being merged at this point because
it offers basic functionality, and from an API standpoint, things
are complete.

SIP work is *not* feature-complete; however, with the completion
of the SUBSCRIBE/NOTIFY API, all APIs (except a PUBLISH API) have
been created, and thus it is possible for developers to attempt
to create new SIP work.

API documentation can be found in the doxygen in the code, but
usability documentation is still lacking.
