Ander Conselvan de Oliveira 9aeff2b5c5 lib/kms: Add a way to override an output's mode 
So that it is possible to use a custom mode with the simplified mode set API.

v2: Add documentation for igt_output_override_mode(). (Thomas)

* There are two parts in this library: First the low level helper function
* which directly build on top of raw ioctls or the interfaces provided by
* libdrm. Those functions all have a kmstest_ prefix.
*
* The second part is a high-level library to manage modeset configurations
* which abstracts away some of the low-level details like the difference
* between legacy and universal plane support for setting cursors or in the
* future the difference between legacy and atomic commit. These high-level
* functions have all igt_ prefixes. This part is still very much work in
* progress and so also lacks a bit documentation for the individual functions.
*
* Note that this library's header pulls in the [i-g-t framebuffer](intel-gpu-tools-i-g-t-framebuffer.html)
* library as a dependency.

* expected to fail, so that the error code can be checked for correctness.
* For changes that are expected to succeed, use @igt_display_commit instead.
*
* Note that in non-atomic commit styles, no display programming will be
* performed after the first failure is encountered, so only some of the
* operations requested by a test may have been completed. Tests that catch
* errors returned by this function should take care to restore the display to
* a sane state after a failure is detected.
