Currently ctrl_id is being used to decide whether to allow or not
certain control dynamically i.e. after stream on.
Use CAP_FLAG_DYNAMIC_ALLOWED to do the same instead.

- 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.

Incase of synchronous cmd(HFI_CMD_INIT, HFI_CMD_STOP, HFI_CMD_CLOSE)
timeout cases, video driver will attempt to do core_deinit sequence
and will free all interface queues mappings as part of core_deinit.
If at same time ISR handler is fired then reverse thread will attempt
to dequeue packets from message and debug queue. Reverse thread will
not acquire core->lock for performance reasone. Dequeueing packets
without acquiring core->lock might lead to use-after-free issues.
Uploaded change to address above mentioned issue.

__flush_debug_queue() currently uses core->response_packet
or core->packet for flushing debug queue. So these were
allocated only 4096 bytes, but in read_queue(), boundaries
were checked against VIDC_IFACEQ_VAR_HUGE_PKT_SIZE macro
which is of size 1024 * 12 bytes.
So if FW log packet size is in between 4 KB to 12 KB then
read_queue() allows memcpy() into core->response_packet
or core->packet that will lead to redzone corruption issue
with adjacent alive/valid allocations i.e futher lead to
kernel panic at kfree() sequence(during object validation).
Uploaded change to use same sizes during allocation and
read_queue() validation.

Sometimes uninitialized local pointer variables were passed to
msm_vidc_vmem_alloc() call for allocating memory. Uninitialized
variables might garbage value, so msm_vidc_vmem_alloc() is
treating that double alloc request and returning error. So i.e
leading to undefined behaviour.
For e.x, msm_vidc_update_input_cr() call will never add any
entries into &inst->enc_input_crs(due to above mentioned issue),
So i.e leading to populate invalid input compression ratio in
encoder usecase.

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.

Subscribe and enable HFI_PROP_TRANSCODING_STAT_INFO property
in order to enable transcoding stat for decoder.
This stat is used further by encoder to improve encoder quality
decision for transcode case.
Ideally we want to avoid CAC-BRS multiple times for same encoded bitstream.
When user does recording (1st encode), So we have CAC enabled bitstream.
Now, if user wants to send it via some app.
So, it will be decode -> (optional GPU) -> (2nd) encode
For 2nd encode -> we would like to not apply same CAC. It needs either tuning.
But we don't have a way from bitstream to know whether it went via CAC.
This feature enables to use the stat info received from decoder to fine tune encoding.
