Test if futex_waitv() returns -EWOULDBLOCK correctly when the expected
value is different from the actual value for a waiter.

The test plan for TAP needs to be declared immediately after the header.
This adds the test plan API to kselftest.h and updates all callers to
declare their expected test counts.

Convert test to use ksft TAP13 framework to print user friendly
test output which is consistent across kselftest suite.

Most of the tests under selftests follow a pattern for their results,
which can then be parsed easily by other external tools easily. Though
futex tests do print the test results very well, it doesn't really
follow the general selftests pattern.
This patch makes necessary changes to fix that.
Output before this patch:
futex_requeue_pi: Test requeue functionality
Arguments: broadcast=0 locked=0 owner=0 timeout=0ns
Result: PASS
Output after this patch:
futex_requeue_pi: Test requeue functionality
Arguments: broadcast=0 locked=0 owner=0 timeout=0ns
selftests: futex-requeue-pi [PASS]

The futextest testsuite [1] provides functional, stress, and
performance tests for the various futex op codes. Those tests will be of
more use to futex developers if they are included with the kernel
source.
Copy the core infrastructure and the functional tests into selftests,
but adapt them for inclusion in the kernel:
- Update the Makefile to include the run_tests target, remove reference
to the performance and stress tests from the contributed sources.
- Replace my dead IBM email address with my current Intel email address.
- Remove the warrantee and write-to paragraphs from the license blurbs.
- Remove the NAME section as the filename is easily determined. ;-)
- Make the whitespace usage consistent in a couple of places.
- Cleanup various CodingStyle violations.
A future effort will explore moving the performance and stress tests
into the kernel.
