stagefright: misc fixes to software video encoders (and decoders)
- move logic to set encoder parameters to common encoder class
(similarly to what was done for decoders)
- set compressed buffer size based on frame size and compression ratio,
and codec-specific minimum size
- set raw buffer size based on frame size and metadata mode
- do not set stride and slice height on compressed ports
- advertise only QCIF support for google H263 encoder
- set large-enough input size for video decoders to support adaptive
playback
- do not change input buffer size on output port reconfiguration, as
no input buffer reallocation takes place
- do not return empty buffers with EOS after EOS has been signaled

stagefright: fix surface input handling of software encoders
- added SoftVideoEncoder for common color conversion and
extension handling logic
- fix YUV420 SemiPlanar handling that should be NV12 not NV21

Support VP8 encoder key frame interval and number of
temporal layers configuration.
- Change ACodec.cpp to populate VP8 extra parameters
structure with key frame interval, number of temporal
layers and quantization parameters.
- Change software VP8 encoder to select frame temporal
patterns and temporal layers bitrate distribution based
on the number of layers similar to patterns used in WebRTC.
- Calculate video frame duration in VP8 encoder from the
timestamps.

A few fixes in SW VP8 encoder:
- Increase encoder output buffer size to 1 Mb to avoid buffer
overrun when encoding high complexity HD frames.
- Store output port format parameters.
- Use same VP8 encoder settings as in WebRTC when encoder is
configured to run in CBR mode.

Experimental support for enabling the use of "surface input" mode
even with the software VP8 encoder.
This relies heavily on the fact that the "Nexus" devices use ARGB32 as
the colorspace for the data underlying a surface provided by SurfaceFlinger
(mirroring). Generally there are no such guarantees.

Adds VP9 decoding support for stagefright.
Also change the VP8 encoder role name from
video_encoder.vpx to video_encoder.vp8 for
future VP9 encoder support.
Requires the change in frameworks/native and media_codecs.xml
corresponding to the device.
VP9 decoding test will be added to cts repo later.

Adds VPX encoding support for stagefright.
Only following encoder settings are available
- target bitrate
- rate control (constant / variable)
- frame rate
- token partitioning
- error resilience
- reconstruction & loop filters
Only following color formats are recognized
- YUV420Planar
- YUV420SemiPlanar
- AndroidOpaque
Following settings are not configurable by the client
- encoding deadline is realtime
- the algorithm interface for encoder is vp8
- fractional bits of frame rate is discarded
- timebase is fixed to 1/1000000
Requires libvpx to be built with encoder support enabled.
Requires openmax 1.1.2 extension headers.
Relevant tests exist in cts repo.

Revert "Adds VPX encoding support for stagefright."
This lib was not part of the build, but it is built anyway for userdebug image (not for eng though).
let me revert it for now...
This reverts commit 6c6bb9873f55853fe74d8f45ad3ae116636d8be7.
