[PATCH 1/6] lib/string_choices: add few more convenient choice helpers

[Dmitry Antipov]

Looking over a few kernel subsystems I'm currently working
on, I suppose that 'str_pass_fail()', 'str_passed_failed()',
'str_lock_unlock()' and 'str_locked_unlocked()' with their
opposite counterpart macros may be useful as well.
