c747b3b12a clang compiler warnings: Fix -Winitializer-overrides
This patch fixes clange compiler warnings for initializer overrides.
Specifically:

res_pjsip/config_transport maps PJSIP_TLSV1_METHOD to the same enumeration
value as PJSIP_SSL_DEFAULT_METHOD. When initializing an array containing
those enum values, we therefore initialize the value twice to two different
values, "tlsv1" and "default". This patch changes it to just initialize
the index in the array to "tlsv1".

e62bd46511 res_pjsip: make it unloadable (take 2)
Due to the original patch causing memory corruptions it was removed until the
problem could be resolved. This patch is the original patch plus some added
locking around stasis router subcription that was needed to avoid the memory
corruption.

Description of the original problem and patch (still applicable):

The res_pjsip module was previously unloadable. With this patch it can now
be unloaded.

This patch is based off the original patch on the issue (listed below) by Corey
Farrell with a few modifications. Namely, removed a few changes not required to
make the module unloadable and also fixed a bug that would cause asterisk to
crash on unloading.

This patch is the first step (should hopefully be followed by another/others at
some point) in allowing res_pjsip and the modules that depend on it to be
unloadable. At this time, res_pjsip and some of the modules that depend on
res_pjsip cannot be unloaded without causing problems of some sort.

The goal of this patch is to get res_pjsip and only res_pjsip to be able to
unload successfully and/or shutdown without incident (crashes, leaks, etc...).
Other dependent modules may still cause problems on unload.

Basically made sure, with the patch applied, that res_pjsip (with no other
dependent modules loaded) could be succesfully unloaded and Asterisk could
shutdown without any leaks or crashes that pertained directly to res_pjsip.

2b0777c017 res_pjsip: Make transport cipher option accept a comma separated list of cipher names.
Improvements to the res_pjsip transport cipher option.

* Made the cipher option accept a comma separated list of OpenSSL cipher
names.  Users of realtime will be glad if they have more than one name to
list.

* Added the CLI command 'pjsip list ciphers' so a user can know what
OpenSSL names are available for the cipher option.

* Updated the cipher option online XML documentation to specify what is
expected for the value.

* Updated pjsip.conf.sample to not indicate that ALL is acceptable since
ALL does not imply a preference order for the ciphers and PJSIP does not
simply pass the string to OpenSSL for interpretation.

4d2c7c23f8 PJSIP: Handle defaults properly
This updates the code behind PJSIP configuration options with custom
handlers to deal with the assigned default values properly where it
makes sense and adjusting the default value where it doesn't. Before
applying this patch, there were several cases where the default value
for an option would prevent that config section from loading properly.

126334a7aa res_pjsip: ami: Fix error in AMI output when an endpoint has no transport
When no transport is associated to an endpoint, the AMI output for
PJSIPShowEndpoint indicates an error instead of silently ignoring the
missing transport.

This patch causes the error to appear only if a transport was specified
on the endpoint and the transport doesn't exist.  It also fixes an issue
with counting the objects that were actually found.

365ae7523b res_http_websocket: Close websocket correctly and use careful fwrite
When a client takes a long time to process information received from Asterisk,
a write operation using fwrite may fail to write all information. This causes
the underlying file stream to be in an unknown state, such that the socket
must be disconnected. Unfortunately, there are two problems with this in
Asterisk's existing websocket code:
1. Periodically, during the read loop, Asterisk must write to the connected
   websocket to respond to pings. As such, Asterisk maintains a reference to
   the session during the loop. When ast_http_websocket_write fails, it may
   cause the session to decrement its ref count, but this in and of itself
   does not break the read loop. The read loop's write, on the other hand,
   does not break the loop if it fails. This causes the socket to get in a
   'stuck' state, preventing the client from reconnecting to the server.
2. More importantly, however, is that the fwrite in ast_http_websocket_write
   fails with a large volume of data when the client takes awhile to process
   the information. When it does fail, it fails writing only a portion of
   the bytes. With some debugging, it was shown that this was failing in a
   similar fashion to ASTERISK-12767. Switching this over to ast_careful_fwrite
   with a long enough timeout solved the problem.

Note that this version of the patch, unlike r417310 in Asterisk 11, exposes
configuration options beyond just chan_sip's sip.conf. Configuration options
to configure the write timeout have also been added to pjsip.conf and ari.conf.

a4906e9f86 sorcery: Create AST_SORCERY dialplan function.
This patch creates the AST_SORCERY dialplan function which allows someone to
retrieve any value from a sorcery-based config file.  It's similar to 
AST_CONFIG.

The creation of the function itself was fairly straightforward but it required
changes to the underlying sorcery infrastructure that rippled into individual
sorcery objects.  The changes stemmed from inconsistencies in how sorcery
created ast_variable objectsets from sorcery objects and the inconsistency
in how individual objects used that feature especially when it came to
parameters that can be specified multiple times like contact in aor and match
in identify.  You can read more here...
http://lists.digium.com/pipermail/asterisk-dev/2014-February/065202.html

So, what this patch does, besides actually creating the AST_SORCERY function,
is the following...

* Creates ast_variable_list_append which is a helper to append one ast_variable
  list to another.
* Modifies the ast_sorcery_object_field_register functions to accept the
  already-defined sorcery_fields_handler callback.
* Modifies ast_sorcery_objectset_create to accept a parameter indicating return
  type preference...a single ast_variable with all values concatenated or an
  ast_variable list with multiple entries.  Also fixed a few bugs.
* Modifies individual sorcery object implementations to use the new function
  definition of the ast_sorcery_object_field_register functions.
* Modifies location.c and res_pjsip_endpoint_identifier_ip.c to implement
  sorcery_fields_handler handlers so they return multiple occurrences as an
  ast_variable_list.
* Added a whole bunch of tests to test_sorcery.

f0b8590c14 pjsip configuration: Make transport TOS values consistent with endpoints
Transport TOS values were interpreted as DSCP values without being documented
as such. Endpoint TOS values (tos_audio/tos_video) behaved normally as TOS
values have historically. This patch makes the transport TOS values behave as
TOS values and makes all TOS values readable as string values (e.g. AF11).
In addition, alembic scripts have been updated to use the proper field types
for all TOS/COS values.

* 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.

9bad1dabcf Add a reloadable option for sorcery type objects
Some configuration objects currently won't place nice if reloaded.
Specifically, in this case the pjsip transport objects.  Now when
registering an object in sorcery one may specify that the object is
allowed to be reloaded or not.  If the object is set to not reload
then upon reloading of the configuration the objects of that type
will not be reloaded.  The initially loaded objects of that type
however will remain.

While the transport objects will not longer be reloaded it is still
possible for a user to configure an endpoint to an invalid transport.
A couple of log messages were added to help diagnose this problem if
it occurs.

735b30ad71 The large GULP->PJSIP renaming effort.
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"
