9988e1b6ee cap_v4l: Fix private control enumeration end condition
Currently the private control enumeration will be stopped when QUERYCTRL
returns -EINVAL only. It is possible however that other errors occur.

One particular case is when the v4l2 device doesn't support any controls
and doesn't implement the QUERYCTRL ioctl. In that case the v4l2
framework returns -ENOTTY. In that case the current control enumeration
will go in an endless loop.

To fix this change the control enumeration stop condition. If any errors
occur, end the control enumeration.

a527e8cc73 cap-v4l: remove unwanted loop in V4L2 mainloop
The while loop would run only once making it useless and leading
to confusion.

So, remove the unwanted while loop and just keep an infinite for
loop.

dadde75ef0 use struct member width_set/height_set to replace static width/height.
the static variables will cause race-condition when operating in
multithread scenarios.

9629af1aa9 videoio: MSMF async reader for camera stream
Synchronized reading from camera with heavy frame processing
provides bad effects (huge frame latency, processing frames from the past).
Generally, there is no way to process each frame and some frames will be dropped.
Allow preventive frame dropping to reduce lag of processed frames.

This mode is applied to cameras only (opened by 'index').
