Introduces a flag that disables SRTP extensions in DtlsControl so that it can be reused in non RTP streams.

Adds method for sending data over DTLS layer to the transformer. Returns application data packets from transform method.

Implements DefaultTlsServer.getRSAEncryptionCredentials() which may be required by certain cipher suites.

Fixes the list of cipher suites supported by the DTLS server so that it reflects the capabilities of the actual Bouncy Castle implementations at this time.

Lets RTP packets generated from mute data sources from time to time in order to fix an issue at the receiver which could cause it to get out of sync with respect to the SRTP index of the sender. Issue reported and fix suggested by Emil Ivov.

Always uses Jitsi's own gain control because the use of PulseAudio's stream-specific volume control is reported to undesireably maximize the volume (https://java.net/jira/browse/JITSI-1050).

Fixes an issue which could cause SRTP to start failing to authenticate RTP packets after a number of RTP packets indicated as generated from a muted audio source were dropped.

Mitigates an issue with sample rate conversion in Windows Audio Session API (WASAPI) which leads to audio glitches.
