MediaExtractor: Add more skip conditions for the second-pass extractors

If the stream's container is opaque (DRM) or a known skip condition
(cached-source MPEG4), don't push it through the deep scanner

audio:Avoid VideoLagUpdate if there is no AudioPlayer

-When AudioTrack is failed to initialized, mAudioPlayer
 is deleted in onVideoEvent but onVideoLagUpdate() is still
 trying to access mAudioPlayer which is leading to a crash.
 The function onVideoLagUpdate() is used to notify if video
 is lagging behind audio. So this function is no longer
 valid if AudioPlayer is deleted.

-Fix is to add a check for AudioPlayer in onVideoLagUpdate,
 which will avoid onVideoLagUpdate() if there is no
 AudioPlayer

NuPlayer: Fix ANR while resetting RTSP playback

- When network is poor, the response of RTSP teardown won't be received
  in time, so ANR will happen.
- With this patch, a teardown message will be sent when timeout expires,
  in order to avoid ANR.

libstagefright: Fix to free buffers in error scenarios

- MediaBuffer objects are not freed if component transitions from
  IDLE->EXECUTING or EXECUTING->LOADED fails (or if the
  OMX_CmdComplete messages are dropped due to an earlier error)
  Additionally with native buffers, the corresponding
  ANativeWindowBuffers are not cancelled back in the above scenarios.

audio: Fixed condition to load AAC HW Encoder

- UseQCHWAACEncoder checks if the bitrate passed by the
  client is in the supported bit rate range of the
  AAC Hw Encoder. It is wrongly compared with the
  sample rate passed by the client instead of bitrate
  This is leading to loading of Hw Encoder even when
  unsupported bitrate is passed

- Fix is to correct the condition to compare with bitrate
  instead of sample rate

libstagefright - Fix seek on audio having empty stss block

Ignore stss block for audio even if its present, all audio
sample are sync samples itself, self decodeable and playable.

Parsing this block for audio restricts audio seek to few entries
available in this block, sometimes 0, which is undesired.

libstagefright: set frame packing from codec config

- From ACodec call to configure codec is triggered but there is no frame
  packing call
- In default configuration, clips may fail if the proper frame packing
  mode is not set
- Codec config and frame packing are currently done in two separate calls.
  Fix is to trigger frame packing from within the codec config call as
  there is no reason to call each separately

Fix memory leak when filtering commands in insertCommand_l()

When AudioPolicyService::AudioCommandThread::insertCommand_l filters
a command from the queue, the AudioCommand* is removed from the
vector mAudioCommands by calling mAudioCommands.removeAt(). This will
destroy the pointer and compact the vector, but not delete the
AudioCommand object.

This patch adds code to delete a filtered out AudioCommand and its
data object mParam. However, mParam was void* and deleting a void
pointer is undefined behavior according to the C++
standard. Therefore, the data classes are modified to inherit
from an abstract base class with a virtual destructor.

The deletion of non-filtered commands in
AudioPolicyService::AudioCommandThread::threadLoop() was already
correct, as each case casts mParam to the proper type before
deleting.

This also fixes AOSP issue 36370.
