Camera2/3: Fix deadlock when starting recording before preview.

Move 3A notification synthesis for HAL3 devices from
Camera3Device::processCaptureResult to Camera2Client's
FrameProcessor. This will ensure that calls to processCaptureResult
from HAL can never block on Camera2Client internal mutexes.

libstagefright: support for disabling buffer metadata

- Metada mode video recording is enabled by default.
- use setprop debug.camcorder.disablemeta 1 to disable metadata mode recording.

Camera: QCOM legacy definitions,HTC cam switch,NO_UPDATE_PREVIEW

Updating Camera parameters, and service with several
compatibility patches:

1., QCOM legacy CameraParameters and functions:
Adding these will make ICS qcomm camera blobs work on JB 4.3.
Use BOARD_USES_QCOM_LEGACY_CAM_PARAMS := true in BoardConfig
to use this.

Also fixes the problem of legacy qcom
camera blobs with recent libcameraservice QCOM_HARDWARE changes,
where the orientation is messed up on first
preview: the fix is leaving out setPreviewWindow(window) for
legacy qcomm cam blobs.

2., Also adding NO_UPDATE_PREVIEW flag for legacy purposes.

3., Adding adding the set orientation patch:
Always set buffers orientation when setting the qcom camera preview window
Fixes the rotated preview on TouchPad
https://github.com/CyanogenMod/android_frameworks_base/commit/1a8e41a3c7434737db89b604352575f8b3109e7a

4., camera: Full support for HTC camera switch

5., Adding more parameters for HTC Explorer

Camera: Fix deadlock due to mLock in pcb and takepicture

In non-zsl case of takepicture, we do streamoff for preview
stream which is waiting on preview callback thread to exit.
By that time the lock has already been acquired by takePicture.
So preivew callback will not exit until it acquires lock and
takePicture cannot continue until PCB call back is returned.
Fix: Avoid the mLock at services when both Preview cb &
Compressed cb are enabled.

Camera: Disable TakePicture related messages in stopPreview,stopRecording

This change fixes the race condition and avoid the deadlock
in abnormal snapshot stop I.e, Observed DeadLock when Data
or Notify Callbacks is sent to App after StopPreview is
triggered and so disabling the corresponding take picture messages.

audioflinger: Fix to prevent deadlock in AudioEffects

-Write is blocked waiting for effect chain lock and this causes
decoder thread to wait indefintely.
-Sometimes it is observed that effectschain is locked before
mLPAEffectChain is initialized and but unlocking is skipped if
mLPAEffectChain is initialized in between.Due to this LPA
silence and framework reboot issues are observed as
applyEffectsOn() cannot acquire lock to progress further.
-Use flag to check if all effects have been locked and unlock
accordingly to prevent the deadlock scenario.

libstagefright: Reset the decoder while performing seek

-Observed noise when seeking to beginning of file for the recorded
AMR clip.
-While performing seek, the AMR decoder states are not being reset.
In AMR decoder, the current frame output is predicted using the states
from previous frame. If these states are not cleared, it might cause
noise when seek is performed.
-Fixed by resetting the decoder when seek is issued and port flush
completion is notified to the decoder.

Revert "audioflinger: Fix buffer size for VOIP"

This reverts commit f16d2ca71b6006aacf758b85ceac2f6314185725.
audioflinger: Use channel count for buffer size calculation

- For VOIP(hangout) usecase, when the ringtone is played,
  application sets flag as VOIP and the channel as stereo.
  But , on the server (audioflinger) side , the channel
  was always considered as MONO. This was leading to a
  corruption of the Cblk.
- Added changes to consider channel count in allocating the
  buffer size.

libstagefright: Add support for custom LPA buffer size

 * On msm8930, during playback over A2DP with DSP Manager effects enabled,
   there's a lot of stuttering with the default buffer size. Stock kernel
   used a buffer size of 32, but that caused no audio at all in CM because
   of mismatch in buffer size between kernel and user space. So up until
   now I've been using a buffer size of 256 to get audio working at all,
   but unfortunately it causes stuttering as mentioned. Hence add support
   for a custom buffer size so we can revert to stock value used in kernel,
   and enjoy no stuttering.

libstagefright: optimize thumbnail generation path

- Checking for YUV420SP format support is not intended for software
  decoders and can be skipped. This avoids unnecessary creation of
  hardware decoders for checking supported output formats.
- Change the flag from kPreferSoftwareCodecs to kSoftwareCodecsOnly.
  This will force software codecs to be tried first and not just "prefer"
  which helps when a software codec for a particular type of codec (like
  divx) doesn't exist and avods creation of hardware codecs twice in case
  of hardware failure.

audio: fix for deadlock issue during LPA playback

EffectModule::setEnable for LPA playback was modified to lock
AudioFligner::mLock with EffectModule::mLock held.
And at the same time ~DirectAudioTrack is trying to lock
EffectModule::mLock with AudioFlinger::mLock held and this
results in deadlock.
Fix this issue by reverting previous change and acquire
locks in certain sequence to avoid deadlock in setEnabled_l

libstagefright: Add pause support for hardware omx component

-ADSP doesn't enter sleep state after wma playback is paused
and power suspended.
-No support for NT session pause in case of hardware component.
NT session need to be paused to put ADSP into power collapse.
-Add support of pause in stagefright to ensure device enters
suspend mode. Also add intermediate states to avoid concurrency
issues between read and pause.
