Originally we did the same thing with SRTP that we do without SRTP,
which is to simply not send packets when e.g. sleep is called.

At commits d6332397 and
5259814a we enabled sending silence
packets with comfort noise when SRTP is active.  We appear to have
done this for interop purposes; many devices can't handle gaps in the
stream of SRTP packets.

But our current comfort noise implementation doesn't take the codec
rate into account (FS-6291), so on 16kHz codecs the constant we chose
created an annoying level of static between sound file playback.

With this commit we preserve the sending of SRTP packets during idle
periods, but make those packets completely silent.

fix race condition where a transferring leg could be hungup on by the bridge partner from the previous bridge because of hangup held leg detection.  The leg which was hungup when held doesn't realize the other leg has already moved on from the bridge because it was transferred and is already on its way to connect to the new destination

Our sqlite fork was reading past the end of the zP3 KeyInfo structure

FS-5888 --resolve Rather than changing the default behavior I've updated the log line to be more accurate. Also fixed the problem where the delay was being overwritten.

Pre-jessie versions of Debian's mk-build-deps tool rely on libraries
that do not correctly parse debian/control, so we have to clip it down
to a smaller subset of the format to build on e.g. wheezy.

Clean up the libpq autodection and make sure it functionswith both pg_config and pkg-config.

if you are installing into a non-FHS standard location such as what happens with RPMs from the Postgres yum repo, you will need to make sure pkg-config can fild the libpq.pc file.
example: export PKG_CONFIG_PATH=/usr/pgsql-9.3/lib/pkgconfig

you may also want to make sure your path can find pg_config
example: export PATH=/usr/pgsql-9.3/bin:$PATH

./debian/util.sh build-all will do a number of builds in sequence or
parallel.  We now track if any of those builds fail to return a
.changes file and exit non-zero.
