In commit 7efeabbd Anthony fixed the
handling of sip:example.com and sips:example.com URLs, however he
introduced a regression causing URLs starting with 's' to be parsed
incorrectly.

In commit 7d2456ea Brian fixed the
regression, but introduced a regression causing sips:example.com URLs
to be handled incorrectly.

Order the default configure flags in the order they show up in
configure --help, and order our own alphabetically.

When --enable-fhs is passed to configure, we set all paths by default
in a way compliant with FHS, the Filesystem Hierarchy Standard.

Each path may still be overridden by passing the specific flag for it.

This previous change fixes the issue on 64bit but if trying to compile a 32bit build you end up breaking the types on 32bit.

Commandline Fu for dumping the various defines for gcc are as follows:

gcc -m64 -dM -E - <<<''

gcc -m32 -dM -E - <<<''

FS-6226Prevent DTMF from traversing bridged channels, but still allow me to send DTMF via API or dp app (uuid_send_dtmf or send_dtmf)

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.

This shows the cipher name, TLS version, the number of cipher bits and
algorithm bits, and a description of the cipher in Sofia's debug
logging output on level 9.

sha1_init, sha1_update, and sha1_final were ending up as undefined
symbols in libfreeswitch.so because of the inline declaration, which
caused us to blow up while linking the freeswitch executable.  Declare
these as static inline instead.

These files were introduced in commit 72e2d183.

Unlike fread(3), read(3) will return -1 on error.  We were assigning
the result of read to a potentially unsigned variable, and passing the
result down to switch_xml_parse_str() where it would end up
determining how many bytes to malloc(3).

FS-5886 --resolve add NDLB_broken_opus_sdp which must be set as a global variable in var.xml or switch.conf.xml to enable broken opus mode for back compat with counterpath mobile

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
here.  This was causing gcc and clang's address sanitization to alert.
