[Intel-gfx] [PATCH 3/3] [RFC] lib: add igt_main macro

[Daniel Vetter]

In the past new testcases with subtest often forgot to add the call to
igt_exit at the end of their main() function. That is now caught with
a bit more obnoxious asserts, but it's still a nuissance.

This little igt_main macro takes care of that (and also of calling the
subtest machinery initialization code correctly).

If no one objects I'll roll this out for all the simple cases (i.e.
those tests that don't have additional argv parsing on top of the
subtest machinery).
