- Creates an AbstractRTCPTerminationStrategy that takes care of all the
  boilerplate code for RTCP termination strategies and shall serve as a
  base for all RTCP termination strategies. This newly introduced class
  acts an RTCP compound packet transform chain. Inheritors can add
  transformers to that chain and generate RTCP reports.
- Moves the receiver feedback filtering functionality from the
  BasicRTCPTerminationStrategy into a new ReceiverFeedbackFilter class
  (a specialized RTCP compound packet transformer) so that it can be
  reused more easily.
- Moves the feedback cache updating functionality from the
  BasicRTCPTerminationStrategy into a new FeedbackCacheUpdater class (a
  specialized RTCP compound packet transformer) so that it can be reused
  more easily.
- Merges the ReceiverReporting class into BasicRTCPTerminationStrategy.
- Refactors the BasicRTCPTerminationStrategy and the
  HighestQualityRTCPTerminationStrategy as specializations of the
  AbstractRTCPTerminationStrategy.

blocking if we try to send too much through a TCP socket.

Removes a restriction on the use of PulseAudio devices based on a particular sample format reported by GitHub user agh1467. Removes "superflous" source code reported by "Matt" in the comments of GitHub pull request #36 "Remove condition for S16LE sample format".

This prevents any device registered as a different format from
showing up in the device list.

Fixes invocations of JNI functions with incorrect arguments, modifications of JNI values which are to be treated as const, dangerous discards of return values of JNI functions.

Moves ConfigUtils and StringCompiler from videobridge to libjitsi util package, so that they can be reused in  other Jitsi projects.

extensions added in the beginning of the transformer chain.
