KUnit aborts the current thread when an assertion fails. Currently, this is done conditionally as part of the kunit_do_failed_assertion() function, but this hides the kunit_abort() call from the compiler (particularly if it's in another module). This, in turn, can lead to both suboptimal code generation (the compiler can't know if kunit_do_failed_assertion() will return), and to static analysis tools like smatch giving false positives.
Moving the kunit_abort() call into the macro should give the compiler and tools a better chance at understanding what's going on. Doing so requires exporting kunit_abort(), though it's recommended to continue to use assertions in lieu of aborting directly.
In addition, kunit_abort() and kunit_do_failed_assertion() are renamed to make it clear they they're intended for internal KUnit use, to: __kunit_do_failed_assertion() and __kunit_abort()
