libstagefright: Drain input buffer on resume

- Buffers returned from codec in paused state are not drained. When
codec is resumed these buffers are not drained until the next flush,
and may cause timed out issue.
- Added change to drain input buffers for sw decoders when resuming.

stagefright: ExtendedCodec: enable arbitrary/frame-by-frame mode

Based on the parser's hint, explicitly enable arbitrary or frame-
by-frame mode rather than assume component's default mode.

stagefright: yield callbackDispatcher to writer safely

Dispatcher acquires the OMXCodec instance (add ref) and
removes ref each time it dispatches a message. If removing
of ref is not guarded by the lock, based on timing,
dispatcher thread might be the last one to own OMXCodec and
ends up deleting OMXCodec instance from its own context.
Destruction of OMXCodec from dispatcher's context will also
freeNode, remove dispatcher, forcing dispatch-thread to join
itself.
On Android, this will not block itself, but may lead
to a race condition where [b] comes before [a].
[a] wait for the thread to finish (join)
[b] return from destructor (delete object memory)

libstagefright/omx: Fix logic to handle dead observers.

  OMXNodeInstance freeNode tries to tear down OMX component
  if not in OMX_StateLoaded. It handles all other states except
  OMX_StatePause. This change adds OMX_StatePause handling.

StagefrightRecorder: Pause audio encoder on recorder pause

  When the recorder is paused, OMXCodec-based audio encoders will wait
  for output buffers, timing out after 3 seconds. Pause the audio encoder
  to avoid a timeout error.

libstagefright: Copy the entire buffer from/to OMX component

stagefright: Handle acquireWakeLock failure case

When the power service is not running, acquireWakeLock fails, but
TimedEventQueue still keeps a reference count to a non-existent
wakelock. This causes an assertion failure when trying to free the
wakelock. Only increment the reference count and save the wakelock
reference on successful acquire.

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

libstagefright: Extended media support via FFMPEG

libstagefright: add null checking to addPlugin

libstagefright: fix error handling of dlsym()

According 'man dlsym', a NULL return from dlsym() doesn't indicate an error.
The correct way to test for an error is to call dlerror() to clear any old
error conditions, then call dlsym(), and then call dlerror() again to check
whether its return value is not NULL.

libstagefright: add more media mimetypes

This is the first step to add the ffmpeg plugins.

libstagefright: add ExtractorPlugin

The patch allows to load an ExtractorPlugin to extend the functions of
DataSource::sniff and MediaExtractor. A plugin has to implement a C
function getExtractorPlugin to fill the MediaExtractor::Plugin struct.

The filename of the plugin could be specified by the
media.stagefright.extractor-plugin property.

FLACExtractor: Add more sample rates support

In FLACExtractor.cpp, it has function to check file's sample rate.
If the input sample rate is not in its list, it will return "unsupported
sample rate" issue. Modify code to make other sample rates (100,1k,42k,46k)
pass the check

libeffect: Fix enabled effect count calculation error

When switching from tunnel to arm effects, effect chain will be moved
from offload thread to mixer thread. During this procedure effect instance
is not destroyed, instead it's preserved and mounted onto new chain.

The migrant sequence is 1) disable instance -> 2) move to new effect
chain -> 3) enable instance again. However, the accumulated effect
enabled count is not decreased when effect instance is disabled.

As a result, LvmBundle_process() is only called once when Effect_process()
called twice, which causes input buffer get processed alternately and
glitch sound appears.
