Export the kmsg() function for use by tests to write into the kernel
message log, useful for tests to inline their progress with kernel error
messages.

When tracking down the cause of a particular kernel warning, knowing
which file it is associated with can be a big clue. So write the
filename into the kernel message log prior to opening it.

If I may suggest an alternative - timestamp igt messages and write a log
interleaver to be used with kernel log and igt log as inputs?
That would avoid having to sprinkle igt_kmsg over igt code base as more
interesting scenarios are discovered.

How do you get igt_log over netconsole?

Hm, ok. But should we then just send igt logs to two places? Stdout/err
and kmsg? Could be an environment option or something if required.

There are quite a few igt logs that would be nice in the kernel log,
pretty much anything info+. Maybe debug+ if we push some of the noise
out of debug and down into even lower-priority-debug.
