  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

When all-reg-options-ping is enabled, this adds a new custom event to mod_sofia
(sofia::sip_user_state), which is fired when a client stops responding to such
ping packets (or when it is reachable again).

Add two needed new columns to the sip_registrations table:
  - ping_status, which is "Reachable" or "Unreachable" depending on the client
    status;
  - ping_count, which tracks the number of ping responses received and is used
    to provide some kind of hysteresis to avoid firing the event in case of
    transitory network failures.

Then ping_count is checked against two threshold values, sip-user-ping-min
and sip-user-ping-max in a similar fashion as the ping-{max,min} options for
the gateways. These two values are configurable in the profile's xml
configuration file.

Also, if unregister-on-options-fail is enabled, the client is unregistered
based on the number of OPTIONS failure which is also checked against the
sip-user-ping-{min,max} values.

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