1. Adds a native RTP bridge technology which does local or remote bridging depending on conditions
2. Makes the bridging core aware of native bridges
3. Calls into the compatible callback of bridging technologies when present to check compatibility
4. Tweaks some logic to cause the bridge to reconfigure when external conditions influence it</pre>

2. Tested that if conditions allow it that remote bridging (ala reinvite) occurs
3. Tested that if remote bridging is not possible that local bridging occurs
4. Tested that if conditions are not correct none of the above happens
5. Tested that external applications cause the bridge to be reconfigured, and alternate technology used if needed</pre>
