libstagefright: fix drainInputBuffers for FlushCompleteEmulation Quirk

Codecs which use the "requires-flush-complete-emulation" require
flushing (draining) the buffers before filling them. The change
"accelerate camera recording start up speed" has changed the order
of filling and draining the buffers which doesn't work well with
the FlushCompleteEmulation quirk

* Move the OMAP_ENHANCENEMENT flag to make sure that the
  buffer is not modified futher on.
* Don't queue more than 4 buffers to the component. This
  greatly improved the video recording framerates both for
  480P and 720P.

stagefright: fix YV12 chroma stride align for Exynos4

Commit 906eba (exynos4: libstragefright: add support for samsung colorformat/omx/mfc)
was supposed to apply YV12 chroma stride align to 16 for the Planar format but was
mistakenly applied for all the other formats.

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.
