* Disable H.264 for android firefox
* Fix syntax error for rule
* lower case
* Remove disabled codec from AddTrackRequest
* Consistent handling of enabled codecs
Mainly cleaning up where we are doing codec filtering.
There's also behavior change of how we handle codec compatibility. If a client doesn't support the client's desired codec, we'll pick a backup automatically
instead of rejecting the client's request.
Requires an update on multi-codec simulcast handling.
* fix alternative codec selection
