Improved deadlock detection logs.
This should make it easier to debug the "object was locked by" logs.
Display tid and pthread_t of both the lock owner and the caller in the
"object was locked by" warning log about potential deadlocks.
This makes it easier to figure out what's going on with ps -t
which only shows the tid not the pthread_t.
Reduce false positives by using a generation counter to look for forward
progress, at the risk of increasing the chance of more false negatives.
Use lock with timeout to reduce chance of missing an "unlocked" window.

Bug 5147281 prefetch status deadlocks
Fixed two deadlocks related to AudioTrack prefetch event callbacks:
- if PrefetchStatus interface was initialized on an AudioPlayer,
there was a deadlock at the point where it checked whether to do a callback
- prefetch status callbacks are now called with the object unlocked,
so they are permitted to do APIs on the object
Miscellaneous fixes:
- SMP-safe locks for GetPrefetchStatus, GetFillLevel,
GetCallbackEventsMask, SetFillUpdatePeriod, GetFillUpdatePeriod
- SetCallbackEventsMask error handling for invalid bitmask
- Enqueue sets prefetch fill level to 1000

Bug 4603165 playback rate change
Non-trivial implementation is only for AudioTrack with rate range 500
to 2000 per mille and property SL_RATEPROP_NOPITCHCORAUDIO; for Android
MediaPlayer the rate range is 1000 to 1000 per mille.
Details:
- no multi-range
- fix SMP races in GetRate, SetPropertyConstraints, GetProperties
- SetRate only updates mRate if successful
- Rate_SetPropertyConstraints only updates mProperties if successful
- return SL_RESULT_FEATURE_UNSUPPORTED for non-AudioPlayers
which have this interface (currently only MidiPlayer)
- for Android, atomically set playback rate and constraints
and simplify to use hard-coded constraints rather than querying
- per the spec, SetPropertyConstraints now returns
SL_RESULT_PARAMETER_INVALID if the constraints are out of range,
or SL_RESULT_FEATURE_UNSUPPORTED if the constraints are in range but
not supported by this implementation

Implement XAVideoDecoderCapabilitiesItf
Add support for the OpenMAX AL XAVideoDecoderCapabilitiesItf
engine interface.
Implement the Android support of this interface in
VideoCodec_to_android.*. This functionality relies
on OMXCodec::QueryCodecs() feature, and does only
expose hardware codec capabilities (see full note in
VideoCodec_to_android.h).
Add sample code to list the platform's video decoders
and their profile / level combinations.

Clean up main header
There are many includes in sles_allinclusive.h that should be moved
to the files that rely on those headers. This is a first cleanup
to move Android audio effect related headers to where they belong.
+ one relocation for a media server related file. More to come
with AudioPlayer refactoring.

Bug 3329759 callback mask for TS streaming
- declare a "buffer event" item key and the event mask matching
the OpenSL ES 1.1 buffer queue event mask
- added a buffer state field in AdvancedBufferHeader to keep
track of the lifecycle of a buffer in the queue
- in StreamPlayer, store a constant to be sent as the item
each time a buffer is dequeued because it's been processed
- fix bug in playStream test app where after clearing the
queue, the data was read to the last dequeued buffer address,
rather than at the beginning of the cache.

Bug 3329759 Implement streamInformation and volume in OpenMAX AL
- Implement StreamInformation for video size notification.
- Implement the XAVolumeItf for volume control
- Fix bug in GUID -> MPH hash.
- Fixed typo in GenericPlayer::pause() log
- Do not signal a discontinuity automatically when the ABQ is
cleared because clearing the queue doesn't imply there will
be a discontinuity in the data (e.g. the same data that was
cleared could be reenqueued)
- In "native-media" test app: add test code to exercise the
XAVolumeItf functionality.

Bug 3329759 support commands in SLAndroidBufferQueueItf
Support for EOS, DISCONTINUITY, and DISCONTINUITY with
a PTS.
- in IAndroidBufferQueue structure, added buffer type
- modified AdvancedBufferHeader structure to have a buffer
type-specific structure that contains all the items for each
buffer
- added parsing of items when enqueueing a buffer
- enforce buffer size enqueue to be a multiple of MPEG-2 TS
block size for buffer of the corresponding types
- when enqueueing a buffer on an empty queue, implemented
an asynchronous notification on StreamPlayer to consume
the newly queued buffer. Verified this kicks off playback
after having starved the framework for buffers.
- report unknown duration when using AndroidBufferQueue

Bug 3329759 TS streaming over SLAndroidBufferQueueItf
Modify the SLAndroidBufferQueueItf interface to offer a model
where buffers of data can be queued along with commands
(messages) when used for playback, or buffers of data can be
received along with metadata (messages)
changes:
- new callback and enqueue functions in SLAndroidBufferQueueItf
and XAAndroidBufferQueueItf.
- definition of a new struct, AdvancedBufferHeader, for
the buffers in the queue.
- decoupling of the "buffer available to be filled" from SF
and the call to the ABQ callback. Implemented in new
file AndroidBufferQueueSource.cpp
- source/sink checks and memory allocation when creating an
AudioPlayer or MediaPlayer that uses SLAndroidBufferQueueItf,
and verifying the data fed to the ABQ is declared as
SL_CONTAINERTYPE_MPEG_TS
- updated tests/native-media XA demo code, and
tests/sandbox/streamSource to use the new interface.
