623832b94e res_pjsip_outbound_authenticator_digest: Add context to log messages
There was no context info in this module's log messages so it was
impossible to toubleshoot.

Added endpoint or host to all messages and added the realms in the
challenge for the "No auth credentials for any realm" message.

c5b9ed20fd res_pjsip_session: Add cleanup to ast_sip_session_terminate
If you use ast_request to create a PJSIP channel but then hang it
up without causing a transaction to be sent, the session will
never be destroyed.  This is due ot the fact that it's pjproject
that triggers the session cleanup when the transaction ends.
app_chanisavail was doing this to get more granular channel state
and it's also possible for this to happen via ARI.

* ast_sip_session_terminate was modified to explicitly call the
  cleanup tasks and unreference session if the invite state is NULL
  AND invite_tsx is NULL (meaning we never sent a transaction).

* chan_pjsip/hangup was modified to bump session before it calls
  ast_sip_session_terminate to insure that session stays valid
  while it does its own cleanup.

* Added test events to session_destructor for a future testsuite
  test.

c853cfdc7c res_pjsip/res_pjsip_callerid: NULL check on caller id name string
It's possible for a name in a party id structure to be marked as valid, but the
name string itself be NULL (for instance this is possible to do by using the
dialplan CALLERID function). There were a couple of places where the name was
validated, but the string itself was not checked before passing it to functions
like 'strlen'. This of course caused a crashed.

This patch adds in a NULL check before attempting to pass it into a function
that is not NULL tolerant.

If ICE is enabled and a STUN server does not respond then we will block

earlier to prevent these retransmissions.

Occasionally a crash happens when processing the RTCP DTLS timeout
handler.  The RTCP DTLS timeout timer could be left running if we have not

standard RTCP mode to RTCP multiplexed mode.

f856cfbb51 rtp_engine/res_rtp_asterisk: Fix RTP struct reentrancy crashes.
The struct ast_rtp_instance has historically been indirectly protected
from reentrancy issues by the channel lock because early channel drivers
held the lock for really long times.  Holding the channel lock for such a
long time has caused many deadlock problems in the past.  Along comes
chan_pjsip/res_pjsip which doesn't necessarily hold the channel lock
because sometimes there may not be an associated channel created yet or
the channel pointer isn't available.

In the case of ASTERISK-26835 a pjsip serializer thread was processing a
message's SDP body while another thread was reading a RTP packet from the
socket.  Both threads wound up changing the rtp->rtcp->local_addr_str
string and interfering with each other.  The classic reentrancy problem
resulted in a crash.

In the case of ASTERISK-26853 a pjsip serializer thread was processing a
message's SDP body while another thread was reading a RTP packet from the
socket.  Both threads wound up processing ICE candidates in PJPROJECT and
interfering with each other.  The classic reentrancy problem resulted in a
crash.

* rtp_engine.c: Make the ast_rtp_instance_xxx() calls lock the RTP
instance struct.

* rtp_engine.c: Make ICE and DTLS wrapper functions to lock the RTP
instance struct for the API call.

* res_rtp_asterisk.c: Lock the RTP instance to prevent a reentrancy
problem with rtp->rtcp->local_addr_str in the scheduler thread running
ast_rtcp_write().

* res_rtp_asterisk.c: Avoid deadlock when local RTP bridging in
bridge_p2p_rtp_write() because there are two RTP instance structs
involved.

* res_rtp_asterisk.c: Avoid deadlock when trying to stop scheduler
callbacks.  We cannot hold the instance lock when trying to stop a
scheduler callback.

* res_rtp_asterisk.c: Remove the lock in struct dtls_details and use the
struct ast_rtp_instance ao2 object lock instead.  The lock was used to
synchronize two threads to prevent a race condition between starting and
stopping a timeout timer.  The race condition is no longer present between
dtls_perform_handshake() and __rtp_recvfrom() because the instance lock
prevents these functions from overlapping each other with regards to the
timeout timer.

* res_rtp_asterisk.c: Remove the lock in struct ast_rtp and use the struct
ast_rtp_instance ao2 object lock instead.  The lock was used to
synchronize two threads using a condition signal to know when TURN
negotiations complete.

* res_rtp_asterisk.c: Avoid deadlock when trying to stop the TURN
ioqueue_worker_thread().  We cannot hold the instance lock when trying to
create or shut down the worker thread without a risk of deadlock.

This patch exposed a race condition between a PJSIP serializer thread
setting up an ICE session in ice_create() and another thread reading RTP
packets.

* res_rtp_asterisk.c:ice_create(): Set the new rtp->ice pointer after we
have re-locked the RTP instance to prevent the other thread from trying to
process ICE packets on an incomplete ICE session setup.

A similar race condition is between a PJSIP serializer thread resetting up
an ICE session in ice_create() and the timer_worker_thread() processing
the completion of the previous ICE session.

* res_rtp_asterisk.c:ast_rtp_on_ice_complete(): Protect against an
uninitialized/null remote_address after calling
update_address_with_ice_candidate().

* res_rtp_asterisk.c: Eliminate the chance of ice_reset_session()
destroying and setting the rtp->ice pointer to NULL while other threads
are using it by adding an ao2 wrapper around the PJPROJECT ice pointer.
Now when we have to unlock the RTP instance object to call a PJPROJECT ICE
function we will hold a ref to the wrapper.  Also added some rtp->ice NULL
checks after we relock the RTP instance and have to do something with the
ICE structure.

f882ca2572 modules: change module LOAD_FAILUREs to LOAD_DECLINES
In all non-pbx modules, AST_MODULE_LOAD_FAILURE has been changed
to AST_MODULE_LOAD_DECLINE.  This prevents asterisk from exiting
if a module can't be loaded.  If the user wishes to retain the
FAILURE behavior for a specific module, they can use the "require"
or "preload-require" keyword in modules.conf.

A new API was added to logger: ast_is_logger_initialized().  This
allows asterisk.c/check_init() to print to the error log once the
logger subsystem is ready instead of just to stdout.  If something
does fail before the logger is initialized, we now print to stderr
instead of stdout.

cd80af508e res_rtp_asterisk.c: Add stun_blacklist option
Added the stun_blacklist option to rtp.conf.  Some multihomed servers have
IP interfaces that cannot reach the STUN server specified by stunaddr.
Blacklist those interface subnets from trying to send a STUN packet to
find the external IP address.  Attempting to send the STUN packet
needlessly delays processing incoming and outgoing SIP INVITEs because we
will wait for a response that can never come until we give up on the
response.  Multiple subnets may be listed.

0939a19cff res_xmpp: Correct implementation of JABBER_STATUS & JabberStatus
The documentation for JABBER_STATUS (and the deprecated JabberStatus
app) indicate that a return value of 7 indicates that the specified
buddy was not in the roster. It also indicates that you can specify a
"bare" JID (one without a resource). Unfortunately the actual behavior
does not match the documented behavior.

Assuming that our roster includes the buddy online and available
"valid@example.org/Valid" and does *not* include the buddy
"invalid@example.org", the JABBER_STATUS() function returns the
following before this patch:

+------------------------------+------------+--------------------------+
| Buddy                        | Status     | Result                   |
+------------------------------+------------+--------------------------+
| valid@example.org            |  Online    |  7 (Not in roster)       |
| valid@example.org/Valid      |  Online    |  1 (Online)              |
| valid@example.org/Invalid    |  N/A       |  7 (Not in roster)       |
| invalid@example.org          |  N/A       |  Error logged, no return |
| invalid@example.org/Valid    |  N/A       |  Error logged, no return |
+------------------------------+------------+--------------------------+

And after this patch:

+------------------------------+------------+--------------------------+
| Buddy                        | Status     | Result                   |
+------------------------------+------------+--------------------------+
| valid@example.org            |  Online    |  1 (Online)              |
| valid@example.org/Valid      |  Online    |  1 (Online)              |
| valid@example.org/Invalid    |  N/A       |  6 (Offline)             |
| invalid@example.org          |  N/A       |  7 (Not in roster)       |
| invalid@example.org/Valid    |  N/A       |  7 (Not in roster)       |
+------------------------------+------------+--------------------------+

This brings the behavior in line with the documentation.
