With -Wmissing-prototypes the compiler will warn about non-static functions which don't have a prototype defined. As they are not used from a different compilation unit they don't need to be defined globally.

Avoid the issue by marking the functions static.

__sync_bool_compare_and_swap() is deprecated and requires libatomic on GCC. Compiler toolchains don't necessarily have libatomic available, so avoid this requirement by using atomics that don't need libatomic.

To get rid of setjmp()/longjmp(), the teardown logic needs to be usable from __bail(). Introduce a new callback for it.

Usage of longjmp() was added to ensure that teardown is always run in commit 63e6b2a42342 ("selftests/harness: Run TEARDOWN for ASSERT failures") However instead of calling longjmp() to the teardown handler it is easier to just call the teardown handler directly from __bail(). Any potential duplicate teardown invocations are harmless as the actual handler will only ever be executed once since commit fff37bd32c76 ("selftests/harness: Fix fixture teardown").

Additionally this removes a incompatibility with nolibc, which does not support setjmp()/longjmp().

Show how to use the kselftest harness together with nolibc. This just runs the existing harness selftest by crudely replacing the regular nolibc-test.c with the harness-selftest.c to get that wired up easily. To use it: $ cd tools/testing/selftests/nolibc/ $ ./run-tests -m user

In the future nolibc-test can use the harness for itself.
