Media (not Video)

• WebRTC 1st tranche landing scheduled for tomorrow morning early EDT (6-8am EDT-ish). Try builds percolating, both webrtc disabled (the default), and enabled (since I want it to work after it lands if enabled).
• Per the plan, trying to land while it's relatively quiet. Landing will be on inbound, with default for webrtc disabled so impact should be low.
• Talking with glandium and ted about how to deal with webrtc signaling needing deep interaction with DOM (PeerConnection, MediaStreams, etc) and with media/webrtc/trunk (media code). We're going to test static-linking gkmedia with PGO and without PGO and see what the memory use on the builders is.
