Bug: 32023356
Test: make vts.

preload elementary stream information during decoding

instead of using extractor to get the frame boundaries, frame
flags and timestamp information, they are read from a metadata
file in the resources directory on demand. Instead of doing it
on demand, we load the entire file information and use it. This
modification comes in handy for future test fixtures

bug fix: wait on input consumption

after queuing all the frames that need to be processed by
the component, the application continues its job of deinitializing
the component before ensuring all the inputs were decoded.
This is corrected.

add end of stream test for audio decoder

component is provided an input with nFlags field set OMX_BUFFERFLAG_EOS.
the application expects this flag to be returned via one of its output
buffers. this flag is passed to the component at different timings to test
the robustness.

add timestamp deviation test for decoder components

the list of timestamps received from the component is
compared with the list provided to the component for any
differences

add option to configure resource files path

default location of resource files is /sdcard/media/. client can provide
choice of this location via the option -P.

example: VtsHalMediaOmxV1_0TargetVideoDecTest -C <component> -R <role> -P /sdcard/res/

add flush test for audio & video dec components

while decoding a group of frames, flush call is made and it is
checked if all the i/o buffers are sent back to client. we then
seek to the next keyframe and test for decoding. monotonous
increase of timestamps is ensured.
