Remove integer sanitization from ringbuffer pointer arithmetic
The AudioTrackShared ringbuffer uses int32 positions and allows overflow.
This confuses the integer sanitization code and makes it panic.
The simplest solution for now seems to be to remove sanitization
from the methods that touch the ringbuffer pointers.

AudioTrack: fix stall if setBufferSizeInFrames() called before play()
The server was waiting for a full buffer.
But the buffer was only getting partly filled.
So the stream was not starting.
The fix involves having the server look at the adjustable threshold.

audio: Fix race condition in AudioTrack underrun.
When audio flinger mixer removes an AudioTrack from the
active list in case of underrun, it is possible that the
client has written a full buffer just after the underrun detection and
is blocked waiting for more space to write. In this case, the client
will never detect the DISABLED flag and the track never be restarted.
Also implement missing DISABLE flag detection in server side audio tracks
(OutputTrack and PatchTrack).

libmedia: Preserve futex return status in client obtainBuffer
clock_gettime() can change errno if something goes wrong (most
commonly setting EBADF). This failure should not cause a failure
in ClientProxy::obtainBuffer() if the futex returned successfully
or with a known status. Preserve errno before calling clock_gettime
to prevent propagation of an invalid, unexpected error.

Prevent ANR when AudioTrack is paused or re-routed
If ClientProxy was interrupted by AudioTrack::pause() just before futex syscall() in obtainBuffer() was called,
It will not call releaseBuffer to wake up AudioTrackThread.
It puts the AudioTrackThread to sleep and then a deadlock occurs.
In this case, CBLK_INTERRUPT flags can't prevent a deadlock,
so this patch set mFutex to FUTEX_WAKE during interrupt() to avoid deadlock.
A similar problem could occur due to re-route or recovery after mediaserver death.

Fix missing loop count for static tracks.
StaticAudioTrackServerProxy::framesReady() previously returned
only the contiguous frames, update to return the total
available frames. This resolves short-count looping in
SoundPool for FastTracks.
Also (1) Removes the racy condition of reading two variables
and (2) Fixes buffer->mNonContig to return the correct value
and (3) Restores behavior that loop count of 1 goes back to
loopStart once during playback.

Allow releaseBuffer after flush
After AudioTrack start checks for pending flush,
allow releaseBuffer on any previously obtained buffer.
For example, this can happen if the resampler has obtained
a buffer but not released the whole buffer yet.
Note that the resampler will be reading obsolete data.

AudioTrack: fix head position after restore
The head position transfered to the new track
by restoreTrack_l() must take into account the frames that
are dropped from the old track to avoid a non recoverable
offset in the playback head position returned to applications.

Fix underruns when fast track denied due to SRC
OpenSL ES requests a fast track. If sample rate conversion is needed,
the request is denied by server, and a larger client buffer is used
to handle the higher latency of a normal track. However the client
notification period was calculated based on buffer being divided into
2 sub-buffers. That resulted in the notification period being too long.
The server pulls chunks that are smaller than half the total buffer.
So now the client uses 3 sub-buffers when there is SRC.
Also removed the 'defer wake' optimization because it was incorrect.
This optimization attempted to reduce the number of wakeups of client,
when server releaseBuffer knows that another releaseBuffer will be
following. But there is no way for the first releaseBuffer to predict
how soon the second releaseBuffer will occur. In some cases it was
a long time, and the client underran. So now the client is woken up
immediately if the total number of available frames to client is >=
the minimum number the client wants to see (the notification period).
Also fix bug where minimum frame count was not being used in the
calculation of notification period.

Report underruns for fast tracks also
This fixes a regression that was introduced earlier
by commit 9f80dd223d83d9bb9077fb6baee056cee4eaf7e5
called "New control block for AudioTrack and AudioRecord".
That commit broke underrun reporting for fast tracks.
Also remove Track::mUnderrunCount, which counted the number of underrun
events, and was only used by dumpsys media.audio_flinger.
Now dumpsys media.audio_flinger reports the number of underrun frames,
Isolated underrun-related control block accesses via the proxy, so that
the server is not directly poking around in the control block.
The new proxy APIs are AudioTrackServerProxy::getUnderrunFrames() and
AudioTrackServerProxy::tallyUnderrunFrames(). getUnderrunFrames() returns
a rolling counter for streaming tracks, or zero for static buffer tracks
which never underrun, but do a kind of 'pause' at end of buffer.
tallyUnderrunFrames() increments the counter by a specified number of frames.

libmedia: offloaded playback support
- start() returns a status so that upper layers can
recreate a non offloaded track in case of error.
- Added states to handle offloaded tracks specific:
- waiting for stream end (drain) notification by
audio flinger
- allow pause while waiting for stream end notification
- getPosition() queries the render position directly from
audio HAL.
- disable APIs not applicable to offloaded tracks
- Modified track restoring behavior for invalidated
offloaded tracks: just send the callback and wait for
upper layers to create a new track.
- Added wait for stream end management in audio track client
proxy. Similar to obtainBuffer and should be factored in.

AudioFlinger: offload playback, non-blocking write
- Added specialized playback thread class for offload playback,
derived from directoutput thread.
This thread type handles specific state transitions for offloaded
tracks and offloading commands (pause/resume/drain/flush..) to audio HAL.
As opposed to other threads, does not go to standby if the track is paused.
- Added support for asynchronous write and drain operations at audio HAL.
Use a thread to handle async callback events from HAL: this avoids locking
playback thread mutex when executing the callback and cause deadlocks when
calling audio HAL functions with the playback thread mutex locked.
- Better accouting for track activity: call start/stop and release Output
methods in audio policy manager when tracks are actually added and removed
from the active tracks list.
Added a command thread in audio policy service to handle stop/release commands
asynchronously and avoid deadlocks with playback thread.
- Track terminated status is not a state anymore. This condition is othogonal
to state to permitted state transitions while terminated.

Fix AudioTrack::flush()
It was only flushing at a surface level, and even then only the first time
the server observed the client's flush request. Now it flushes at a
deeper level, but there may be even deeper device-specific flushing.

Use mFutex as an event flag rather than semaphore
An event flag can be more fault-tolerant in case of loss of synchronization,
as it cannot overflow. It also allows more bits to be used in the future.
See http://en.wikipedia.org/wiki/Event_flag

New control block for AudioTrack and AudioRecord
Main differences between old and new control block:
- removes the mutex, which was a potential source of priority inversion
- circular indices into shared buffer, which is now always a power-of-2 size

Start isolating control block accesses in a proxy
The proxy object will eventually be the only code that understands the
details of the control block. This should make it easier to change the
control block in the future.
Initial set of control block fields that are isolated:
- sample rate
- send level
- volume
Prepare for streaming/static separation by adding a union to the control
block for the new fields.
Fix bug in handling of max sample rate on a track. It was only checking
at re-configuration, not at each mix.
Simplify OutputTrack::obtainBuffer.
