When read() from AudioRecord returns 0 or negative value, report an error to application. DO NOT MERGE.

Calculate audio media drift time from AudioSource
The problem was that the time to receive an output buffer
from an audio encoder is different because the encoder does not
need to read from the source for all output buffers. This leads
to large fluctuation in terms of wall clock duration between two
neighboring audio sample outputs from the audio encoder. As a
result, the media time for the video track after adjustment using
the drifting changes wildly sometimes.
This patch addresses this issue by only updating the media drift
time when an audio source input buffer is read. the wall clock
for the audio track is also calculated at the same time when
the input audio buffer is read at AudioSource.

Allows the authoring engine to skip frame.
This is 1st part of the work to allow audio and video resync if
we found out that audio and video are out of sync during authoring
- also fixed a problem in AACEncoder::read() where the buffer acquired
from the buffer group does not release when error out at
reading from source.
