FS-5497 add sofia gateway parameter destination-prefix in case you need to send Invites to your provider with prefix only to this gateway

Depending on which packages are installed, the README.Debian file
might not be there, so we'll spell out the instructions more directly.

On sid the build breaks on "undefined reference to symbol
'ogg_sync_init'".  We'll just avoid mod_shout on sid/jessie until this
is worked out.

The libtool binary used to be contained in the libtool package.  As of
current sid/jessie the libtool package contains everything about
libtool but the libtool binary, and we need to install libtool-bin to
get the libtool binary itself.  Which is to say that Debian decided to
make the libtool package architecture-independent.

Without this commit the FS debian packaging will not build/bootstrap
on sid/jessie.

fix leak of nua handle due to reference counting that must be between 3 to 7 years old.  Effects all calls with auth/challenge on INVITE

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.

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.

It's reasonable for someone to change one or more of these directory
permissions after installation.  We shouldn't touch more than we need
on upgrade.  Each directory needs to be owned by the freeswitch user,
but past that we can leave discretion to the system administrator.

This installs the timezone file such that configurations can reference
it rather than copying it.

Debian has packaged libpq version 9.4beta2.  We were parsing the minor
version as "4beta2" and then trying to treat it as a constant integer,
which obviously doesn't work.

There's not really a perfect way to handle versions like this, so
we'll just pretend it's 9.4.0.

This allows new settings, e.g. new mirrors, to propagate into the
chroot images.
