Since vb2 queue can store more than VB2_MAX_FRAME buffers, the postprocessor buffer storage must be capable to store more buffers too. Change static dec_q array to allocated array to be capable to store up to queue 'max_num_buffers'. Keep allocating queue 'num_buffers' at queue setup time but also allows to allocate postprocessors buffers on the fly. Signed-off-by:

Change the maximum number of buffers of some capture queues in order to test max_num_buffers field. Allow to allocate up to: - 64 buffers for video capture queue. - 1024 buffers for sdr capture queue. - 32768 buffers for vbi capture queue. Signed-off-by:

Use one of the struct v4l2_create_buffers reserved bytes to report the maximum possible number of buffers for the queue. V4l2 framework set V4L2_BUF_CAP_SUPPORTS_MAX_NUM_BUFFERS flags in queue capabilities so userland can know when the field is valid. Does the same change in v4l2_create_buffers32 structure.

Add 'max_num_buffers' field in vb2_queue struct to let drivers decide how many buffers could be stored in a queue. This require 'bufs' array to be allocated at queue init time and freed when releasing the queue. By default VB2_MAX_FRAME remains the limit. Signed-off-by:
