libstagefright: Use proper ctts offset

Calculate ctts offset as difference between composition
time and decoding time, and avoid adding kMaxCttsOffsetTimeUs
as it increases the sample timestamp by the same amount
which leads to av sync loss.

libstagefright: Create Extended Extractor for HEVC and AMRWB+

- Create Extended extractor when
  . Audio format is AMRWB OR
  . Default extractor not able to find any track OR
  . Default extractor finds one track and is Video OR
  . Default extractor finds one track and is neither Audio nor
    Video OR
  . Default extractor finds two or more track, and either Video
    or Audio or both tracks(s) not present OR
  . Default extractor finds both Audio and Video track found and
    Audio format is AMRWB

libstagefright: For interlace, set decoder in arbitrary mode

In arbitrary mode, frame parsers sends individual fields
to core. Once both the field is decoded, output done (FBD)
is sent back to client.
Default frame by frame mode will send both the fields in
a single buffer to core, which might decode only one field
or will throw up error.

libstagefright: Use software audio decoder for HEVC video contents

-Tunnel mode audio is not supported for HEVC video contents. This
 is a dsp constraint because HEVC video is decoded in DSP. Use
 software audio decoder for HEVC video content.

libstagefright: Use appropriate reset call for amrwb decoder

-onPortFlushCompleted is calling Speech_Decode_Frame_reset
 for both AMRNB and AMRWB clips but Speech_Decode_Frame_reset
 is not used for AMRWB decoding. This is causing corruption
 of AMRWB decoder's state during seeking.
-Fix is to call pvDecoder_AmrWb_Reset during AMRWB Decoding

libstagefright: adjust AV sync late margin based on property

- Current AV late margin is 40 ms
- Read system property media.sf.set.late.margin and if
  new AV sync late margin is set then use the same
- Max AV sync late margin allowed is 250 ms
- Min AV sync late margin is default 40 ms

framework/av: Reduce LPA bufsize as to 128KB to save power for SA+

Root cause: SA+ bassboost takes more than two times the MIPS as NXP,
which causes normalized CPU load burst when AP is running, then firing
up 2nd core and consume more power unexpectedly.

Fix: Reducing the LPA buffer size from 256KB to 128KB will decrease the
MIPS required for each round of effect process and keeps the 2nd core
offline.
