Optional HOLD/RETRIEVE signaling for PTMP TE when the bridge goes on and off hold.

Browse Source 
Added the moh_signaling option to specify what to do when the channel's
bridged peer puts the ISDN channel on and off of hold.

Implemented as a FSM to control libpri ISDN signaling when the bridged
peer places the channel on and off of hold with the AST_CONTROL_HOLD and
AST_CONTROL_UNHOLD control frames.

Asterisk Manager Interface
--------------------------
* PeerStatus now includes Address and Port.
* Added Hold events for when the remote party puts the call on and off hold
for chan_dahdi ISDN channels.
Asterisk HTTP Server
--------------------------
* The HTTP Server can bind to IPv6 addresses.
CLI Changes
-----------
--------------------------
* New 'gtalk show settings' command showing the current settings loaded from
gtalk.conf.
* The 'logger reload' command now supports an optional argument, specifying an
alternate configuration file to use.
CDR
---
--------------------------
* The filter option in cdr_adaptive_odbc now supports negating the argument,
thus allowing records which do NOT match the specified filter.
libpri channel driver (chan_dahdi) DAHDI changes
--------------------------
* Added moh_signaling option to specify what to do when the channel's bridged
peer puts the ISDN channel on hold.
