FS-7062: [mod_sofia] on redirect, when uri are passed in without <> with multiple uris, automatically add the q= header param in decending order.  This should make 300 Multiple Choices work well with devices that require the q param.  If you would like to specify explicit q-values, please use the syntax of redirect where you specify the entire header using the <>

As per RFC4856, Annex B mode for G.729 is disabled if the SDP contains a
fmtp parameter annexb=no and enabled if annexb=yes or the annexb parameter
is missing.

When responding to an offer mod_sangoma_codec always returns an answer
without a fmtp parameter. Even in response to a SDP offer which contains
one. This has the effect of responding to a request to disable Annex B
with an answer that only Annex B is supported.

With this change mod_sangoma_codec copies the fmtp parameter from the
offer to the answer fixing the problem.

Fixes a bug where the jitter buffer implementation wasn't discarding
old packets if debug mode was disabled.

FS-7045 #resolve #comment [mod_rayo] guarantee that dialed call can be joined when answered event is sent.

This is nothing more than a shameless copy/paste from another mod_say
module, which already had timezone support. It simply checks if the
timezone variable is set and if it contains a valid timezone, then this
timezone will be used when announcing times/dates.
