WebRTC and WebAudio bugs: Bugzilla search for WebRTC and WebAudio related bugs marked Fixed in Firefox 64

Noteworthy Changes:

• scaleResolutionDownBy and maxBitrate can now be updated live on a connected PeerConnection bug 1253499

• Enable automatic gain control (AGC) by default now in bug 1496714

• SRTP is now using AES CPU instructions (through using NSS instead of build in libsrtp ciphers) and offers AEAD_AES_128_GCM and AEAD_AES_256_GCM through bug 1479665 and some follow up bugs

• Datachannels should get more throughput in most scenarios through bug 1051685
