50f852186f Make device_open() store the VIDIOC_QUERYCAP ioctl errno, and in case
of failure return the stored value rather than the current errno,
which may be overwritten by a following call to close().

932d775fa2 Implement v4l2 input size autodetection in v4l2_read_header().
Move check on frame size after the device is opened and after
device_try_init() is attempted. If the provided size value is 0x0,
perform a VIDIOC_G_FMT ioctl() on the device, which sets size to the
current settings.

5d91e92853 Use avcodec_check_dimensions() for checking the frame size validity.
The v4l.c check is moved after the eventual automatic size detection,
so the check in that case is performed on the new set values.
