bridge_softmix: Forward TEXT frames
Core bridging and, more specifically, bridge_softmix have been
enhanced to relay received frames of type TEXT or TEXT_DATA to all
participants in a softmix bridge. res_pjsip_messaging and
chan_pjsip have been enhanced to take advantage of this so when
res_pjsip_messaging receives an in-dialog MESSAGE message from a
user in a conference call, it's relayed to all other participants
in the call.
res_pjsip_messaging already queues TEXT frames to the channel when
it receives an in-dialog MESSAGE from an endpoint and chan_pjsip
will send an MESSAGE when it gets a TEXT frame. On a normal
point-to-point call, the frames are forwarded between the two
correctly. bridge_softmix was not though so messages weren't
getting forwarded to conference bridge participants. Even if they
were, the bridging code had no way to tell the participants who
sent the message so it would look like it came from the bridge
itself.
* The TEXT frame type doesn't allow storage of any meta data, such
as sender, on the frame so a new TEXT_DATA frame type was added that
uses the new ast_msg_data structure as its payload. A channel
driver can queue a frame of that type when it receives a message
from outside. A channel driver can use it for sending messages
by implementing the new send_text_data channel tech callback and
setting the new AST_CHAN_TP_SEND_TEXT_DATA flag in its tech
properties. If set, the bridging/channel core will use it instead
of the original send_text callback and it will get the ast_msg_data
structure. Channel drivers aren't required to implement this. Even
if a TEXT_DATA enabled driver uses it for incoming messages, an
outgoing channel driver that doesn't will still have it's send_text
callback called with only the message text just as before.
* res_pjsip_messaging now creates a TEXT_DATA frame for incoming
in-dialog messages and sets the "from" to the display name in the
"From" header, or if that's empty, the caller id name from the
channel. This allows the chat client user to set a friendly name
for the chat.
* bridge_softmix now forwards TEXT and TEXT_DATA frames to all
participants (except the sender).
* A new function "ast_sendtext_data" was added to channel which
takes an ast_msg_data structure and calls a channel's
send_text_data callback, or if that's not defined, the original
send_text callback.
* bridge_channel now calls ast_sendtext_data for TEXT_DATA frame
types and ast_sendtext for TEXT frame types.
* chan_pjsip now uses the "from" name in the ast_msg_data structure
(if it exists) to set the "From" header display name on outgoing text
messages.

pjroject_bundled: Add already-destroyed check to tsx_timer_callback
There have been cases that when the transaction timer callback is called
the tsx is already destroyed. This causes a crash. We now check the

pjproject_bundled: Add patch for pj_atomic crashes
There have been some crashes in the past where something attempts
to use a pj_atomic after it's already been destroyed. This patch
tries to prevent it by making sure that pj_atomic_destroy sets
its mutex to NULL when it's done. The pj_mutex functions already check
for a NULL mutex and just return PJ_EINVAL.
Teluu also added some checks to the win32 implementation as well.

This creates a separate source to 'own' symbols related to options.h and

bridge_softmix: Clear "talking" when a channel is put on hold
This patch clears the talking flag from the channel (if already set), and
notifies listeners when that channel is put on hold. Note however, if the
endpoint continues to send audio frames and these are received by the bridge
then that channel will be put back into a "talking" state even though they
are on hold.

pjsip_transport_events.c: Fix crash using stale transport pointer.
Apparently it is possible for the transport to be destroyed without

destroyed and we have a stale pointer in the active_transports container.

destroyed in addition to when it is disconnected and shutdown.

BuildSystem: For consistency, avoid extra libs to be empty.
AST_EXT_LIB_CHECK has several optional parameters. When an optional parameter
is left empty, [] is used to indicate this. However, this is done in the script
./configure only then, when a further parameter is not empty. For example, when
no extra libraries are needed to test the checked library, parameter 5 is not
mentioned. Except parameter 6 and higher are used, then parameter 5 must be
empty.
However, this general rule was broken
* three times for parameter 5 (extra libs) and
* three times for parameter 4 (header)
as found via the Regular Expression \[\]\). In case of parameter 5, all cases
were changed, because that happened for no reason. In case of parameter 4, an
[] improves readability actually. Therefore for parameter 4, the only case which
did not do it was changed. All this aims to create more consistency: Only do
something different if there is a reason to do so.

channel.c: Allow generic plc then channel formats are equal
If the two formats on a channel are equal, we don't transcode and since
the generic plc needs slin to work, it doesn't get invoked.
* A new configuration option "genericplc_on_equal_codecs" was added
to the "plc" section of codecs.conf to allow generic packet loss

Transcoding via SLIN is forced in this case.

BuildSystem: Check for header file of OGG.
Asterisk uses various symbols of the shared library libogg within the module
format_ogg_vorbis. However, the source code of that module did not include the
header file of libogg explicitly but implicitly. Because that header was not
included before Asterisk 14, the script ./configure was told not to check for
it.
Anyway, even Asterisk 13 LTS uses symbols of libogg. Therefore, that header
should be included explicitly. Therefore, ./configure should check for that
header.

./configure --with-pjproject-bundled
did not display an explanation, when no download utility like wget, curl, or

BuildSystem: Remove unused dependency on libltdl.
Asterisk does not need the development package of libltdl, because it does not
use any symbol of -lltdl directly. Instead, it uses the runtime package via the
shared library -lodbc. On the supported platforms, that shared library declares
its dependency on -lltdl correctly, otherwise AST_EXT_LIB_CHECK would have
failed.

BuildSystem: Avoid an extra case for OpenBSD.
Nine years ago with Mantis 13639 (now ASTERISK-12841) an extra case for OpenBSD
was introduced: Vorbis required Ogg to be specified manually, because the shared
library libvorbis.so did not specify its required dependency on -logg itself.
Today with OpenBSD 6.2, all libvorbis*.so declare their dependencies correctly.
Therefore, an extra case is not required anymore.

BuildSystem: Enable Advanced Linux Sound Architecture (ALSA) in NetBSD.
In the script ./configure, AST_EXT_LIB_CHECK checks for external libraries. Some
libraries do not specify all their dependencies and require additional shared
libraries. In AST_EXT_LIB_CHECK, this is the fifth parameter. However, if a
library is specified there, it must exist on the platform, because ./configure
tries to compile/link/execute a small app using those statements. For example,
the library libdl.so is Linux specific and does not exist on BSD-like platforms.
Furthermore, no supported platform/version was found, which still (ever?)
requires those additional libraries. Therefore, they were simply removed.
Finally, this change adds the error code ESTRPIPE to the channel driver
chan_alsa for those platforms which lack it, again for example NetBSD.
