mod_rayo: fix error in SRGS grammar parser... <one-of><item>7</item><item>715</item></one-of> will return MATCH_END with input of 7 instead of MATCH since 715 is a potential match with further input.

This is a convenience option that can be passed to either
debian/bootstrap.sh or to debian/util.sh to include a module in the
build that would normally be excluded.  This option, -p, can be passed
multiple times.

If -t is passed to debian/util.sh, then we will import the
/etc/apt/sources.list mirrors and all apt keys into the
pbuilder/cowbuilder build environment.

This is useful e.g. when the FS build depends on a library not
available in Debian yet.

Normally we override the config of each pbuilder/cowbuilder image when
we update the image before using it for the build.  Passing this
option allows for using an existing cowbuilder image (assuming it's in
the correct location) with some existing desirable configuration.

The packaging for libsngtc-dev is not yet in Debian.

  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.

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.
