lib/igt_kmod: New library to support driver loading/unloading and additional helpers.

lib/igt_aux: Added igt_pkill and igt_lsof helper.
lib/igt_kmod: Added load/unload kmod helpers.

v7:
- document the case where leaving stray fd from drm_open_driver()
might fail reloading the driver.
- list also current opened files from /dev/dri in case we could not
unload the driver.
- convert igt_info to igt_warn (Chris Wilson)
- added KMOD_|PROCPS CFLAGS (Chris Wilson)

v6:
- include latest modifications from tests/drv_module_reload:
display all loaded modules and list information about opened
files by processes (Petri Latvala)

v5:
- added igt_i915_driver_{load/unload}.
- added kick_snd_hda_intel() to match current
tests/drv_module_reload_basic and integrated into
igt_i915_driver_load/unload.
- added gtk-doc section for lib/igt_kmod

v4:
- decided to split libkmod helpers into their own file as there's
another user lib/igt_gvt or tests/gvt_basic.
- fixed some gtk-doc documentation.

v3:
- return -errno (igt_pkill()) in case of failure (Cris Wilson)
- return bool for igt_kmod_is_loaded(), replaced strncasecmp with strncmp
(Chris Wilson)

v2:
- Renamed libkmod helpers (Chris Wilson)
- Removed SIGTERM/SIGKILL case where we repeatedly tried to terminate the
process: just call kill(2) once (Chris Wilson)
- Removed redundant check in igt_kmod_unload(), igt_module_in_use() (Chris
Wilson)
- Pass flags to igt_kmod_unload() from the caller (Chris Wilson)
- Removed useless function igt_kill() which acts just as kill(2) (Chris
Wilson)
