- 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.

- post input psc, output psc and last flag
events to response work handler
- fix issue with release and create internal
buffers during input psc
- clear last flag after session continue
