Simulate an audio output stream when a real one isn't available.
Upgrades FakeAudioOutputStream to fake OnMoreData calls using a
PostDelayedTask approach similar to NullAudioSink.
This is necessary for playback of HTML5 videos when a real audio
device is not present. I.e. over remote desktop w/ remote audio
disabled on on some of the Buildbot machines (this should allow
us to remove --disable-audio from many of our tests).
This is a two fold change:
1. AudioOutputResampler will now request an AUDIO_FAKE device
when invalid output parameters are provided.
2. AudioManagerBase will check for AUDIO_FAKE as it always has
but will additionally check if there are any output devices
and if not return a fake stream.
2 is necessary for HTML5 audio since it doesn't use the low
latency output path.
BUG=120749
TEST=unittests. HTML5/Flash video playback over Remote Desktop
w/o Remote Audio works.
