It's what callers expect - pipe_crc_new is the function where
we pass a potential failure back to callers.

No need to duplicate this all over the place.

This is basically a "drop cache" interface to the igt_debugfs
facilities. Also, update existing users.

No need to sprinkle this all over:
- exit handlers will only be registered once
- they're always called when exiting, so no need to explictly call
them.
This allows us to hide all the pipe crc cleanup in the library.

Have igt_pipe_crc_new() check whether the selected source is actually
supported.
v2: Make debugfs_pipe_crc.c not crash

This was a previous attempt to solve the first CRC being bogus. We know
wait for it and discard it at the end of the function.

With PLANE1 and PIPE CRC sources the test will work on all currently
shipping (and planed fwiw) platforms.
Also add all the other new sources for non-ivb/hsw chips.

Let's add a new test that sets a mode, wait for a few vblanks (3) and
then make sure we read 3 identical CRCs.
Some subtests check for various parsing errors.
In the process, improve the debugfs helpers to deal with CRCs.
