  Remove Contact header from BYE and CANCEL requests.

Merge pull request #65 in FS/freeswitch from ~MBRANCA/freeswitch:bugfix/OPENZAP-220-ftmod_libpri-don-t-close-channel to master

* commit '7ec7c920':
  OPENZAP-220 fix blocked into read and add cause for a correct hangup

    switch_pgsql.c switch_pgsql_next_result_timed() was using switch_time_now() for start time and switch_micro_time_now() for current time.  These are different time sources that may not be in sync and could cause the query to timeout prematurely.

FS-6781: #resolve #comment lets change this to always do confirm to match the other place where we set this

%FEATURE add bypass_media_resume_on_hold and bypass_media_after_hold variables to be set to true to enable these functions on a per channel basis

Per rfc3261 the Contact header is not applicable and MUST not appear in
the request.

FS-5868 #resolve

the other way works better revert 91ffe171 to use high quality on stereo calls

FS-6822 #comment The code in question appears to have been added by me (18f20e24).  I think this patch is the correct solution.

This reverts commit a39db868.

FS-6880 #resolve #comment I would think that in real life once the call agreed on a codec it would only offer the negotiated codecs but we can fix this to always filter for good measure.  I am not sure what the ramifications are of filtering responses but I think this patch will do so as well.

VARIABLE: bypass_media_sdp_filter

Can be set globally or per leg on the inbound side of a bypass_media bridge.

VALID FILTERS:

remove(): Removes the specified codec if it exists in the SDP.
only():   Removes all codecs besides the one specified (providing that it exists in the sdp) (will not remove telephone-event))

EXAMPLE 1 (remove everything leaving only g729):

  <action application="set" data="bypass_media_sdp_filter=only(g729)"/>
  <action application="set" data="bypass_media=true"/>
  <action application="bridge" data="sofia/internal/1238@conference.freeswitch.org"/>

EXAMPLE 2 (remove everything leaving only g729 and also remove dtmf):

  <action application="set" data="bypass_media_sdp_filter=only(g729)|remove(telephone-event)"/>
  <action application="set" data="bypass_media=true"/>
  <action application="bridge" data="sofia/internal/1238@conference.freeswitch.org"/>

EXAMPLE 3 (remove alaw and speex):

  <action application="set" data="bypass_media_sdp_filter=remove(pcma)|remove(speex)"/>
  <action application="set" data="bypass_media=true"/>
  <action application="bridge" data="sofia/internal/1238@conference.freeswitch.org"/>
