Revert "Fix decoder EOS handling"

 * This is causing carnage for apps and games which make assumptions
   about the (bad) behavior of EOS handling. While this patch makes
   it consistent across the board, let's stay bug-for-bug compatible.
 * L is going to break a lot of shit :(

This reverts commit ff9a42d3c4460714dcb963f1a9f22f06a8f7fc8d.

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.
