DataSource: Split off ffmpeg sniffer to a second pass, and only if necessary

ffmpeg's sniffer is intended as a grab-all-that-doesn't-work-elsewhere
extractor. Unfortunately, this causes two issues:

- As written, it requires ffmpeg to whitelist any extractors supported
by stagefright, or else it will blindly override them. This has codebase
sync issues, as shown by the VP9 and WAV accidental overrides
- It imposes an in-depth analysis of _all_ media, even that which we
want to be processed quickly by shipping stagefright plugins (hardware
or not). This is mostly noticeable in network streams and thumbnail
generation.

This patch moves FFmpegExtractor to an independent sniffer queue, and
it only invokes it when the regular MediaExtractor hits 1 of 3 conditions:

1 - The confidence in the identified container type is low
2 - No container is identified at all
3 - A video container was found by other extractors, but only 1 stream
(audio or video) was identified.

libstagefright: Check for data partitioned clips

- Check for DP clips in ESDS atom of mpeg4 clips
- If the clip is detected to have data partition, return a
  error, so that video decode will fallback to SW decoder

libstagefright: handle error when B-frame is sent to MPEG4Writer

Without this patch, writing B-frame to MediaMuxer will be blocked and
cannot return a result. This may cause an endless progress bar shown in
gallery when triming or muting some videos.

stagefright: Cancel audioCheck event when setting nativewindow

In html5 playback, setNativeWindow_l() will be called twice
when switching from landscape to portrait mode. If the 2nd
setNativeWindow_l gets the LOCK before proceeding mCheckAudioStatusEvent
posted in the 1st setNativeWindow_l, it will get the infomation
that seeking is completed and won't do seeking in this run.

audio: Fix for failure in CTS MediaRecorderTest cases

 -Issue: MediaRecorder CTS test cases are failing.

 -Running the CTS test "testRecorderRandomAction" at
  beginning sets the huge file size and StageFrightRecorder
  set the 64 bit file offset. In MPEG4 writer
  estimateMoovBoxSize depends on a static const variable
  which uses this file offset info. As the variable to
  calculate estimateMoovBoxSize is static const it remains
  same for next media recording session even if file size
  is small.

 -Fix: Don't use static const variable which is used to
  calculate estimateMoovBoxSize as its value may change
  depending on file offsets.

RTSP: Fix crash issue while repeated pause/resume

While doing repeated pause-resume operation in RTSP streaming,
some times, the accessunit timeout check is being posted when
the streaming paused, and even after receving the EOS.
Due to this check, after the EOS, the number of packets received
will be zero and the session gets Teardown while the
streaming is paused. Upon resume, it leads to check failure and crash.

Changes are done such that the accessunit timeout check will
not be done in pause/seek state.

camera: Disable extra HDR frame on QCOM_HARDWARE

Qualcomm camera HALs default to adding an extra zero-exposure frame
to HDR snapshots; this is breaking third-party apps, and we don't
use it in system-bundled apps, so disable it unless explicitly
requested by the client

audio: mute duration at the beginning of recording

-AudioSource mutes for predefined duration (kAutoRampStartUs)
 at the beginning of a recording. Current kAutoRampStartUs
 is not sufficient to mute the shutter sound click on
 B-Family devices. Sometime shutter sound is getting recorded
 with the current kAutoRampStartUs.

-Issue with calculating muteDuration from getOutputLatency is,
 more delay is getting added for Bt(~1 sec) which is really not
 required.

-Fix is to use constant mute delay which is appropriate

libstagefright: Fix to handle EAGAIN error on first read to source

 -Some of AV streaming clips are not played
 -In streaming use case when source does not have sufficent data it
  return error EAGAIN on first read request, player ignore this error
  and treat it as a first buffer.
 -Make the read request again to source on EAGAIN error.

stagefright: yield callbackDispatcher to writer only for video

Letting Writer run increases the probability of dispatcher
not getting the lock when it comes back with the next message.
This adds an extra sleep-wakeup and increase power consumption.

Since Audio dispatcher handles more messages, this behavior
is profound in case of audio. Contain yielding business to
video only since this optimization is not required for audio.
