FS-4916 added beep real beep instead of DTMF, and fixed hangup before end of greeting. I hate the world and the world hate me

mod_voicemail_ivr: Added the new param for API vm_fsdb_pref_greeting_get WARNING, you must add it to the config or else module will complain of missing value... With the new API, it will now playback the greeting when setting it.  Will need to figure out a better way to deal with api being added in the future...  Add support to auto start new message playback and made it default in the config file.
mod_voicemail_ivr phrases : make value = 0 as plural (0 messages).  Don't tell the option for new message if no new message present.  Changes a few default key to match more closely mod_voicemail key settings.

Audio frame sizes were already being checked for overflow,
but video frame sizes were taken as-is, which would
lead to heap corruption.

In case an overflow has been detected, playback is aborted immediately as
there is no way we can ever recover from such a situation due to the lack
of a (well-known) frame header signature that could be used to skip over
the corrupted part of the streams.

FS-4903: --resolve add/remove records from fifo_outbound not queued so the count query directly follwing gets the correct result

httapi did not pass number of channels up to top level filehandle so stereo files caused buffer overflow

Fix SQL queue manager so it actually stores and executes the pre and post transaction SQL statements.

FS-5019 --resolve  I would rather have this fix in the core... But in the mean this, this look good.  Thanks
