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.

- hierarchical state model which comprises of
top level states and sub states
- top level states include OPEN, CLOSE, ERROR,
INPUT_STREAMING, OUTPUT_STREAMING, STREAMING.
- sub states include DRAIN, DRC, DRAIN_LAST_BUFFER,
DRC_LAST_BUFFER, INPUT_PAUSE, OUTPUT_PAUSE.
- follows deterministic approach for key sequences
like DRC, DRAIN and last flag handling i.e none
of these events are ignored or discarded.
- removal of auto start of firmware input port as
part of ipsc handling.
- introduction of hfi commands for host controlled
PAUSE and RESUME of firmware ports.
- introduction of information last flag packets
for DRC and DRAIN when FW has insufficient
output buffers.

Both &inst->stats_work and &inst->response_work both were using
&inst->response_workq for scheduling works. From reverse thread
handle_session_response_work_handler incremented refcount via
get_inst_ref(), at the same time driverfd got closed by HAL.
So strongref is held by handle_session_response_work_handler and
as part of put_inst(refcount is zero), will attempt to destry
&inst->response_workq inside msm_vidc_close_helper.
destroy_workqueue() call will wait until all already fired events
to complete, which will never happen in this case i.e leading to
deadlock situation. It is an attempt to self destruction, which is
not allowed.
Added changes to avoid above mentioned situation.

- Added change to print buffer statistics like total and avg
etb, ebd, ftb, fbd counts, client set fps, actual fps,
bitrate values in 1 sec window and these stats currently
configured to print at every 1sec boundary.
- Convert meta buffer prints to low level logs.
