pjproject_bundled: Update for pjproject 2.6

* Removed all 2.5.5 functional patches. * Updated usages of pj_release_pool to be "safe". * Updated configure options to disable webrtc. * Updated config_site.h to disable webrtc in pjmedia. * Added Richard Mudgett's recent resolver patches. Change-Id: Ib400cc4dfca68b3d07ce14d314e829bfddc252c7

 When a transport error occured on an INVITE session
 the stack calls on_tsx_state_changed with new state
 PJSIP_INV_STATE_DISCONNECTED and immediately destroys
 the INVITE session.
 At the same time this INVITE session could being processed
 on another thread. This thread could use the session's
 memory pools which were already freed, so we get segfault.
 This patch adds a reference counter and new functions:
 pjsip_inv_add_ref and pjsip_inv_dec_ref.
 The INVITE session is destroyed only when the reference
 counter has reached zero.
 To avoid race condition an application should call
 pjsip_inv_add_ref/pjsip_inv_dec_ref.

 Subject: [PATCH] resolver.c:  Prevent SERVFAIL from marking name server bad
 A name server that returns "Server Failure" is indicating only that
 the server couldn't process that particular request.  We should NOT
 assume that the name server is incapable of serving other requests.
 Here's the scenario we've been encountering...
 * 2 local name servers configured in resolv.conf.
 * An OPTIONS request causes a request for A and AAAA records to go out
  to both nameservers.
 * The A responses both come back successfully resolved.
 * Because of an issue at some upstream nameserver, the AAAA responses
  for that particular query come back as "SERVFAIL" from both local
  name servers.
 * Both local servers are marked as bad and no further queries can be
  sent until the 60 second ttl expires.  Only previously cached results
  can be used.
 * In this case, 60 seconds is just enough time for another OPTIONS
  request to go out to the same host so the cycle repeats.
 We could set the bad ttl really low but that also affects REFUSED and
 NOTAUTH which probably DO signal a real server issue.  Besides, even
 a really low bad ttl would be an issue on a pbx.
