This includes a struct and helpers. It will be used to support container level
cropping and tiled image formats, but should be generic enough for general
usage.

Currently, when writing PCMA or PCMU tracks with FLV or RTMP, the
stereo flag and sample rate flag inside RTMP audio messages are
overridden, making impossible to distinguish between mono and stereo
tracks. This patch fixes the issue by restoring the same flag mechanism
of all other codecs, that ta

When allocating the VAAPIEncodePicture, pic->input_surface can be
initialized right in the place. This movement simplifies the send_frame
logic and is the preparation for moving vaapi_encode_send_frame to the base
layer.
