If two channels enter different native rtp bridges at the same time it is
possible that the framehook interface data pointer can be corrupted
because the struct variable was declared static.

* Fixed the reentrancy corruption by changing the framehook interface
struct static variable to a stack local variable.

* Moved the hook.data assignment outside of the channel lock.  It did not
need the lock's protection.  It probably was giving a false sense of
security.

The testsuite
channels/pjsip/basic_calls/two_parties/nominal/alice_initiated/bob_hangs_up
test caught this with MALLOC_DEBUG and DO_CRASH enabled.

Some compiler optimizers seem to assume that dlopen will not use
__attribute__((constructor)) functions to call back to the program.
This was causing resource_being_loaded to be optimized away completely.

Those SIP messages that create dialogs require a contact header to be present.
If the contact header was missing from the message it could cause Asterisk to
crash.

This patch checks to make sure SIP messages that create a dialog contain the
contact header. If the message does not and it is required Asterisk now returns
a "400 Missing Contact header" response. Also added NULL checks when retrieving
the contact header that were missing as a "just in case".

The bridge holds onto the old channel video source after it's been
released.  This can lead to use after free errors.

Apparently in OSX it's possible for OSX to HAVE_SYSCTL but not
HAVE_SYSINFO or HAVE_SWAPCTL.  In this case freeswap caused an unused
variable error.

* listen uses the variable `s` for the result from ast_poll() then
  overwrites it with the result of accept().  Create a separate variable
  poll_result to avoid confusion since ast_poll does not return a file
  descriptor.
* Resolve fd leak that would occur if setsockopt failed in listen.
* Reserve an extra byte while processing completion results from remote
  daemon.  This fixes a bug where completion processing used strstr() on
  a string that was not '\0' terminated.  This was no risk to the Asterisk
  daemon, the bug was only reachable the remote console process.
* Resolve leak in handle_showchan when the channel is not found.
* Multiple leaks and a deadlock in pbx_config CLI completion.
* Fix leaks in "manager show command".

In change_redirecting_information variables we use ast_strlen_zero to
see if a value should be saved.  In the case where the value is not NULL
but is a zero length string we leaked.

handle_response_subscribe leaked a reference to the ccss monitor
instance.

When a channel that is on hold gets added to a bridge by
the Bridge AMI action or the dialplan application of the same name,
music continues to play, causing "robotic sound".

This commit adds a call to ast_moh_stop to stop the music.
Also, it makes the AMI Park action use the right MOH class when the
channel gets parked.
