run-tests: add possibility for test-runners to report a "warned" test result

A test result is recognized as "warned" when the test runner returns the exit
code False. (False is similar to 0, which is reporting a command has run
sucessfully.)

The only difference in display is that the failure message while running writes
"Warning:" instead of "ERROR:". The diff output is the same as when the test
fails. Runing "run-tests.py -i" asks to accept the changed result also for
tests reported as "warned".

When running tests, a "warned" test would look like this:
..
 --- xxxx\tests\test-something.t
 +++ xxxx\tests\test-something.t.err

+  committing subrepository s/sbs (glob)

   $ echo something

Reporting a test result as "warned" will be used in following patches.
