revamp the voice client.

* split the "voice" debug tag into several tags for usable filtering while debugging
* remove debug-spam from user view by:
  * remove capability request spam by:
    * llstartup the voice client state engine when actually a region is present, and not the initial fake region.
    * don't request a capability to determine if (the very same) capability can be requested.
    * don't do it over and over as if a capability rezzed in like an avatar. Its available - or not (see llstartup).
* unload the daemon if not used.
* load vivox daemon depending on specific criteria in the caps
* remove the partial implementation to load a specific daemon with via the openregion message or the login response.
* discard obsolete caps.

Tested and working on linux: Parcel changing, region changing, (SL) voice-disabled region private call, (SL) private call region changing,  (OS) no voice <-> voice region changing, (OS) mumble <-> freeswitch region changing.
To test: Mac, Win. Anything that needs to be tested and not mentioned above.
