v4l2-compliance: check V4L2_BUF_FLAG_TIMECODE as well

For compressed formats also check V4L2_BUF_FLAG_TIMECODE
for m2m devices. Also show the output buffer flags when
--verbose was specified.

v4l2-compliance: add timeout when waiting for event

The test for the stateful decoder that checks for a SOURCE_CHANGE
event when you start streaming needs to wait for up to one second
before calling dqevent. Otherwise the HW may not have had the
chance yet to raise this event.

So use select() to wait for an exception with a 1s timeout.

v4l-utils: Fix shifting signed 32-bit value by 31 bits problem

Use 1U << 31 instead of 1 << 31 to avoid the 'shifting a signed
32-bit value by 31 bits problem' where the result is compiler dependent.

v4l2-compliance: fix S_SELECTION tests

If a driver doesn't implement S_SELECTION, then these tests return
ENOTTY instead of EINVAL. So just checking against EINVAL isn't
good enough.

v4l-stream.c: add missing copy_cap_to_ref() and fix state

The fwht decoder part was missing the copy_cap_to_ref(): this copies
the decoded frame back to the internal reference frame. This used to
be done in the fwht decoder itself in the past, but after adding
stateless decoder support to vicodec this step was split off into
a separate function.

Also update the state structure initialization: it didn't set
ref_stride and was missing support for 1 or 4 components.

v4l2-compliance: test two stateful encoder corner cases

1) No buffers are queued on either vb2_queue, but STREAMON is called
   for both queues. The next capture buffer queued should return empty
   with FLAG_LAST set.

2) The CAPTURE queue contains buffers, the OUTPUT queue does not. Now
   ENC_CMD_STOP. Check that the dequeued capture buffer is empty and
   has FLAG_LAST set.

v4l2-compliance: improve codec command tests

v4l2-compliance: check stateful encoder format handling

Add tests to check that after setting the output format
the capture format is updated and that the crop rectangle
is set correctly.

Also warn if the output supports composition and fail if
the capture has crop or composition support.
