screenrecord: allow force landscape mode

Some devices' hardware encoder do not support encoding over a
specified height, which may be smaller than the device's display
height in portrait mode. Add a mode which uses landscape encoding
and rotation hint to overcome the limitation.

AudioFlinger: Handle sound card status change

1) Update Audio HAL with sound card status change
2) Call invalidate tracks API on all playback threads so that the
   associated tracks can handle the sound card status change as a teardown
   event

audio: do not allow FAST output for voice call stream type

- Some VoIP applications set AUDIO_OUTPUT_FLAG_FAST while opening
audio output which causes low latency path to be selected. Clear
the flag explictly if the stream type is STREAM_VOICE_CALL
- Add debug messages in Audio Track and Record to print
the requested audio parameters

libstagefright: Fix timestamp corruption during offload playback

-Timestamp gets corrupted at EOS of offload playback.
-This happens because the number of samples played returned from
 HAL could be zero if playback has reached EOS and if compress
 handle is invalid / closed.
-If HAL has posted EOS  avoid the update of real time and media
 time with the timestamp from HAL.

stagefright: add an extra buffer to ANW's BUfferQueue

Add an extra buffer to ensure video player has a free buffer to
dequeue rather than wait for the queued buffer to be displayed.
Enable logs to indicate number of buffers allocated.

NOTE: This is not needed for 30fps content on 60fps panel, But
making this change regardless for all framerates till root-cause
is identified in SF

stagefright: add rendering statistics

 - adds extra fps statistics
 - report via dumpsys
 - prints statistics before reset at the end of playback onto
   logcat
 - adds resume latency, from play_l to render
 - adds seek latency, from seek_l to render
 - enables using persist.debug.sf.statistics 1
 - prints all statistics when seek or resume is issued

libstagefright: Fix intermittent pause during tunnel A-V playback

-Media time is used in onVideoEvent for A-V sync. In offload
 playback we only use realtime(time from DSP).
-Media time should be same as real time. If media time is not
 updated with the real time value A-V sync issues are seen.
-Update media time to real time value to avoid intermittent pause
 during playback.
