Let's just steal the "crc" namespace and add this by default to
igt_pipe_crc_collect_crc() instead of adding more calls to other
tests. If tests want special waits on just some of their collect_crc()
calls, they can use another name instead of "crc".
This is very useful when developing, especially when the CRC we get is
wrong: we want to look at the screen to see what's going on before we
can think about how to fix the problem. So let's add this to the lib
instead of adding this to every single test I need to debug.
v2: Add some documentation (Daniel).

For all those IGT tests that need an easy way to draw rectangles on
buffers using different methods. Current planned users: FBC and PSR
CRC tests.
There is also a tests/kms_draw_crc program to check if the library is
sane.
v2: - Move the test from lib/tests to tests/ (Daniel).
- Add igt_require() to filter out the swizzling/tiling methods we
don't support (Daniel).
- Simplify reloc handling on the BLT case (Daniel).
- Document enum igt_draw_method (Daniel).
- Document igt_draw_get_method_name() (Paulo).
v3: - Add IGT_DRAW_MMAP_WC (Chris).
- Implement the other trivial swizzling methods (Chris).
- Remove the gem_sync() calls (Chris).
