  Fix potential reentrancy problems in chan_sip.

  Asterisk v1.8 and later was not as vulnerable to this issue.

  * Made find_call() lock each private as it processes the found dialogs.
  (Primary cause of ABE-2876)

  * Made the other functions that traverse the dialogs container lock each
  private as it examines them.

  * Fix race condition in sip_call() if the thread that sent the INVITE is
  held up long enough for a response to be processed.  The p->initid for the
  INVITE retransmission could be added after it was canceled by the response
  processing.

  * Made __sip_destroy() clean up resource pointers after freeing.  This is
  primarily defensive in case someone has a stale private pointer.

  * Removed redundant memset() in reqprep().  The call to init_req() already
  does the memset() and is the first reference to req in reqprep().

  * Removed useless set of req.method in transmit_invite().  The calls to
  initreqprep() and reqprep() have to do this because they memset() the req.

  func_audiohookinherit: Document some missed sources.

  This patch also mentions that AUDIOHOOK_INHERIT can be used to
  transfer MixMonitor audiohooks. There is also wiki that addresses
  audiohooks and the use of AUDIOHOOK_INHERIT at the following link:
