[PATCH v3 0/3]: v4l2 microproject (GSoC 2017)

[Edgar Kaziahmedov]

Inhanced informativeness of the ioctl syscall(for the range of
requests owned to v4l2) and tests.

v1: just the first attempt to change(contained mistakes)

v2: added all printings

v3: fixed some mistakes and added tests

NOTE: If it isn't enough, I can do more patches,
because of strace still does not provide the full
informativeness of ioctl syscall(for the range of
requests owned to v4l2).
