[igt-dev] [PATCH i-g-t 0/4] add kselftest runner documentation

[Tales Aparecida <tales.aparecida@gmail.com>]

In the interest of making the code more accessible, add documentation
on structs and functions related to the kselftest.
While writing igt_kselftest_begin() documentation I realized it always
returned 0. Instead of documenting that behavior, the function now
returns non-zero if it fails to open /dev/kmsg.

As an extra, add instructions about writing documentation.

  lib/igt_kmod: fix trivial typos
  CONTRIBUTING: Add reference for GTKDoc
  lib/kselftests: return non-zero on open(kmsg) failure
