We use the transport of the Contact header of the remote UAC to decide
which of our own Contact addresses we should use when replying to a
SUBSCRIBE or sending a presence NOTIFY.
If TLS is not enabled on a Sofia profile, then the TLS Contacts for
that profile are NULL. Unfortunately we were using these NULL values
uncritically when the remote UAC sent us a Contact header with a TLS
transport and our own Sofia profile did not have TLS enabled.
With this commit we fall back to our TCP Contact address when the
remote Contact is TLS and our Sofia profile does not have TLS enabled.
This allows the "broken ptime" detection to work correctly when packet
loss is present on the wire. In addition to the timestamps this patch
adds frame sequence tracking and corrects the timestamp difference
only as needed and according to the number of lost packets.

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.
ADTRAN Total Access devices do not support sending the rport parameter in
the Via header. This allows us to detect the device and force rport when
using the "safe" parameter, enabling the device to be used behind NAT.

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.
