mm-video: venc: Correct a typo in variable name

A kernel variable was to be defined as unsigned long but
it is mistakenly defined as unsigned only, the space is
missing after long. This bug is silent because unsigned
is also a valid data type by itself.
Corresponding to kernel fix, similar correction is done
in userspace code.

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.
