Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to
indicate the test program, extended test program and test files. It is
easy to understand the purpose of these files. But mix of compiled and
uncompiled files lead to duplicated "all" and "clean" targets.
In order to remove the duplicated targets, introduce TEST_GEN_PROGS,
TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled
objects.
Also, the later patch will make use of TEST_GEN_XXX to redirect these
files to output directory indicated by KBUILD_OUTPUT or O.
And add this changes to "Contributing new tests(details)" of
Documentation/kselftest.txt.

Test that performing a copy paste sequence in userspace on P9 does not
result in a leak of the copy into the paste of another process.
This is based on Anton Blanchard's context_switch benchmarking code. It
sets up two processes tied to the same CPU, one which copies and one
which pastes.
The paste should never succeed and the test fails if it does.
This is a test for commit, "8a64904 powerpc: Add support for userspace
P9 copy paste."
Patch created with much assistance from Michael Neuling
