When client queued a buffer, v4l2 framework
compares the client Dmabuf with the existing
dmabuf in the bufs array at the same index.
If the dmabuf is different then v4l2 framework
would call unmap_dmabuf, detach_dmabuf callbacks
for the old buffer and then calls attach_dmabuf,
map_dmabuf callbacks for the new buffer before
qbuf callback is made to driver. If the dmabuf
is same then qbuf callback will be made directly.
V4l2 framework expects that clients recycles the
same buffers in the same indices so that when
v4l2 framework compares dmabuf it won't unmap
or map buffers.
If client recycle the buffers in different indices
still usecase works but there will be unnecessary
unmap, map overhead will be incurred.
If client does not recycle the buffers at all,
meaning every time client queues new buffers
then special handling is required for decoder
output buffers which are used for reference by
video hardware.If any buffers are used by video
hardware as reference buffers then firmware returns
those buffers with READ_ONLY flag and they are kept
in read_only list and when read_only grows beyond
some limit then driver would ask firmware to release
those READ_ONLY buffers and when firmware responds
driver would delete these READ_ONLY buffers.

Acquire client lock for every entry point
in driver. This is needed especially for
streamoff and close calls where inst lock
is released while driver is waiting for
stop_done and close_done responses from fw.
When inst lock is released, client can send
a new ioctl call and driver state machine
can get updated leading to unexpected behaviour.

Reserve duration - Duration by which a session reserves the
video hardware for processing frames from that session.

output metadata buffer's filled length cannot be zero.

Currently MSM_VIDC_BUF_DPB buffer allocated and queued to firmware
as part of output port streamon. Sometimes firmware raises b2b ipsc
with only change in fw_min_count. So client will not follow port
reconfig sequence and calls directly HFI_CMD_RESUME on output port.
So firmware holds only prev set of DPB buffers, which is not sufficient
and it continues to wait for further DPB buffers and that is leading
to stall and testcase fails. So added change to requeue new set of
DPB buffers, incase of b2b ipsc(with only change in count).

There are 2 possible race issues with msm_vidc_stats_handler.
[1] msm_vidc_close acquired inst->lock and called cancel_delayed_work,
by that time stats_handler already fired and incremented inst->kref
via get_inst_ref. Close sequence releases the lock and called
put_inst().
So now inst strong ref is held by stats_handler, which will acquire
inst->lock and schedules new stats_work and does put_inst. inst->kref
count reaches zero and it will free inst struct(using close_helper).
So that will lead to use-after-free crash at core kernel side.
[2] msm_vidc_close acquired inst->lock and called cancel_delayed_work,
by that time stats_handler is scheduled. So process_one_work() from
workqueue is ready to call stats_handler api. But before it invokes
stats handler(context switch), msm_vidc_close sequence continued to
run and completed the close sequence and called put_inst. So inst
struct got freed up(because inst->kref count reached to zero). Now if
core kernel(workqueue) attempts to invoke stats_handler by calling
worker->current_func(work), will lead to again use-after-free crash.
Added changes to avoid above mentioned issues.
