Restore chan_dahdi native bridging and PRI tromboned call elimination.

Browse Source 
Created a native_dahdi bridging technology for use with the new bridging
API.

The new bridging technology is part of the chan_dahdi channel driver
because it is very specific to that driver.  Rather than include the new
code directly into chan_dahdi.c the new bridge technology is in its own
file and linked into chan_dahdi.so.  A large part of this change is the
mechanical process of moving declarations around so chan_dahdi.c can be
split up into more files later.

* Changed the bridging core to pass NULL frames into the channel
technologies instead of discarding them.  The channel technologies may
need the proding to determine if their configuration is still valid.
