Only increase the counter when we do take a wakelock

We keep track on how many wakelocks we have taken. We always
just take one real wakelock but increase / decrease the
counter every time we try to acquire / release a wakelock.
The counter is always increased even if the power manager is
not ready, leading to an incorrect counter that could cause a
crash when we try to release it.
Make sure we only increase the counter when a wakelock, real
or counted, is taken.

update offloaded audio track sampling rate

AudioPlayer must read the sampling rate from offloaded audio sinks
whenever a new time position is computed as the decoder can update
the sampling rate on the fly.

AudioTrack: fix position callback after restore

When restoring an AudioTrack, the next position callback point
should not be modified and set ahead of current buffer head.
Otherwise, as frames are dropped, the new position is never reached
and an application relying on position callbacks to reload the buffer
would be stalled.

fix deadlock issues that arise when there are simultaneous
effect control interface calls to proxy and to
non sub-effect wrappers(eg., bundlewrapper) from audioflinger
Also, return NO_ERROR when CMD_OFFLOAD succeeds

Whenever there are parallel calls to proxy and non sub-effects wrappers,
some of the calls are not completed. This is due to deadlock arsing out
of Proxy waiting for the subeffect call to return and subeffect waiting
for proxy to release lock.
The call flow is changed to a cleaner and simple one - Proxy gets the
aeli(effect library info) of subeffects during the EffectGetSubEffects()
call. Therby, proxy will manage the sub effects by itself rather than
going through effects factory.

audioflinger: fix static track end detection

If a static track is not a fast track,
prepareTracks_l() must rely on framesReady() to
detect end of buffer and remove the track from the active
track list.
Failing to do so results in the track staying active but
not processed by the mixer because in underrun. This leaves the
mix buffer content uninitialized and causes the effect process
function to accumulate its output onto undefined data.

AudioTrack: Never try to use the fast path if resampling is required

Unless AudioFlinger was built with FAST_TRACKS_AT_NON_NATIVE_SAMPLE_RATE
enabled, AudioFlinger would deny using the fast path (and internally
fall back to the normal codepath) when it realized that resampling
was required. Since the buffer size calculations within AudioFlinger
don't take resampling into account properly (see the calculation
below "AUDIO_OUTPUT_FLAG_FAST denied" in audioflinger/Threads.cpp,
just below the hunk that this patch changes), make sure AudioTrack
doesn't try to use the fast path if resampling is required.

This removes the possibility to enable
FAST_TRACKS_AT_NON_NATIVE_SAMPLE_RATE in AudioFlinger since it
AudioTrack now won't even try to use the fast path for content
that requires resampling, regardless of the AudioFlinger configuration.

libstagefright: Fix ANR issue in HTTP Streaming

The root cause of the ANRs during this usecase is the
blocking nature of the read calls on the network data
source due to which application thread gets blocked on
some lock in framework.

Fixes ANR during seek/pause during HTTP streaming
* Non-blocking read implmentation for NuCachedSource2
* Other framework related changes to handle underruns

Add 2 APIs (suspend/resume) in MediaPlayer

- API:suspend() will just pause the player and release all the decoders
  to replace release() which will release the whole player
- API:resume() will just init the decoders again,
  then start() will be called to start to play the streaming
- Add a check in AwesomePlayer::onVideoEvent()
  to make sure the first seek operation will always seek the next i-frame

 libstagefright: Signal input EOS after last buffer is released

-In offload playback, sink stop is called at EOS from the sink call
 back when input EOS is reached. This is called before the last
 buffer is released.
-During seek to the end of clip ,drain can complete even before
 last buffer is released. This can cause playback to switch to
 next stream.
-Fix by ensuring sink stop is called only after the last buffer is
 released.

For now, do not offload LD and ELD AAC decoding because there
is no way to know if it is supported by the audio DSP implementation.
The longer term fix will be to have mapMimeToAudioFormat() use the
audio object type in track metadata to refine the AAC format and the
audio HAL list supported AAC profiles.
