mm-video: vdec: ref count the notifications to secure-display

Notifications to display HAL to secure/unsecure display is sent
when component is created/destroyed. When multiple instances
are created/destroyed, the shared flag which indicates status
of such notification can go out-of-sync.
This change ref-counts the secure status flag and protects it
with a lock.

mm-video: vidc: Fix an issue in flush for Surfacemediasource_test

When i/p flush is in progress, need to give back all the ETB's
to client as EBD's directly instead of post_event. so do not call
push_input_buffer function.

Dashplayer: enable adaptive playback based on codec format key

Added support for prepareForAdaptivePlayback() call in
configureCodec, if max-width and max-height keys are specified
in the format.  It is OK for this call to fail, if component
does not implement adaptive playback.

mm-video: vdec: Support adaptive playback mode

In this mode client checks and sets an extension to indicate
that the content can change resolution, within the pre-
announced maximum height/width. Component over-allocates
buffers for the max resolution and dbp, and notifies client
of any crop change when resolution changes within bounds.

Resolution changes beyond set max width/height will result in
port-reconfiguration notification, while adapting to the new
resolution.

mm-video: vidc: set stride in gralloc-metadata for adaptive-playback

In Adaptive-playback mode, following resolution change, decoder
continues to decode on larger buffer. But the stride is changed
implicitly. Set the updated stride in gralloc-metadata in each
buffer, so HWC/GPU can read the stride to interpret the buffer's
geometry correctly.
