dashplayer: Fix for pause-resume-pause usecase

When pause-resume-pause is queued in fast, second pause
can assert fail in renderer. Happens because pause flag is set
when pause cmd comes but resume flag is set in resume
callback from source. By time resume returns, second pause asserts.

-Fix to remove resume callback path and serialize renderer->pause,
renderer->resume in kwhatpause/kwhatresume as cmds come in itself
-discontinuity flag check made in kwhatresume itself

mm-video: vdec: avoid set metadata after free buffer

In some use cases client frees output buffers before it gets
all FBD's, in this process component clears output buffer
structures it has for current session. Code dependent on
these structures results in crash if it executes after free
buffer. This change checks for such condition and avoids
the same.

mm-video: vidc: vdec: set frame interlace based on firmware flag

Avoid depending on OMX Component h264 parser to read the mbaff
information. Instead the firmware will read mbaff information
and mark the fbd as interlace or progressive.
