Kodicom 4400R and Geovision GV-800 code in bttv driver abuses mbox_we (int)
in struct bttv as char *.
Remove this hack and add a proper sw_status array to struct bttv instead.
This is a a preparation to remove mbox_we.

This commit adds an early check to vidioc_s_std() to detect if the
new and current standards are equal, and exit with success in that
case.
This is needed to prevent userspace applications that might attempt
to re-set the same standard from failing if that's done when streaming
has started.

Remove the check as there's no reason to prevent the input from
being set when the device is streaming. This allows surveillance
applications (such as motion, zoneminder, etc.) to configure the
input while streaming.

check_firmware() makes sure firmware is in a device.
It returns zero on success and error code otherwise.
Also it sets down_firmware flag to 1 if downloading occurs.
The only caller poseidon_probe() checks down_firmware flag and
returns 0 without any initialization if it is set.
That looks very strange, so the patch removes down_firmware argument
of check_firmware() and returns error code if check_firmware() fails
in poseidon_probe().

On mem2mem decoders with a hardware bitstream ringbuffer, to drain the
buffer at the end of the stream, remaining frames might need to be decoded
from the bitstream buffer without additional input buffers being provided.
To achieve this, allow a queue to be marked as buffered by the driver, and
allow scheduling of device_runs when buffered ready queues are empty.
This also allows a driver to copy input buffers into their bitstream
ringbuffer and immediately mark them as done to be dequeued.
The motivation for this patch is hardware assisted h.264 reordering support
in the coda driver. For high profile streams, the coda can hold back
out-of-order frames, causing a few mem2mem device runs in the beginning, that
don't produce any decompressed buffer at the v4l2 capture side. At the same
time, the last few frames can be decoded from the bitstream with mem2mem device
runs that don't need a new input buffer at the v4l2 output side. The decoder
command ioctl can be used to put the decoder into the ringbuffer draining
end-of-stream mode.
