audio: Fixed mBytesRemaining when partial buffers are sent

- When AudioFlinger writes partial buffers to HAL,
  write() on HAl returns period_size if bytes written
  are less than period_size. This is causing
  mBytesRemaining to be negative

- Fix is to check the return value of write() and
  set mBytesRemaining and mBytesWritten correctly

screenrecord: Add audio support

Adds audio recording to the screenrecord system. Note that
while recording, the audio is muted from the device output,
and that the audio volume is controlled separately (so make
sure to turn up your volume if you hear nothing).
Audio from the microphone can also be recorded by adding
--microphone to the command line.

screenrecord: Enable SUBMIX_IN as well and cleanup on exit

While on Nexus 5/Nexus 7 (AOSP QCOM audio), trying to turn on
SUBMIX_IN fails and is not needed, it is required on Find 5
and N1 (CAF QCOM audio), or otherwise SUBMIX_OUT won't turn
on.
We also now release the audio routing as it wouldn't revive
the audio speakers otherwise.
