Subject: [PATCH 00/10] Venus stateful Codec API

Hello,

This aims to make Venus decoder compliant with stateful Codec API [1].
The patches 1-9 are preparation for the cherry on the cake patch 10
which implements the decoder state machine similar to the one in the
stateful codec API documentation.

There few things which are still TODO:
 - V4L2_DEC_CMD_START implementation as per decoder documentation.
 - Dynamic resolution change V4L2_BUF_FLAG_LAST for the last buffer
   before the resolution change.

The patches are tested with chromium VDA unittests at [2].

Note that the patchset depends on Venus various fixes at [3].

Comments are welcome!

regards,
Stan
