For example if we know the tests takes more time because, for example
we are tracing it, or running with very high debug log level we might
not want the test to timeout.
In the normal case the user probably wants to set break point or
anything when running an app in gdb, we should let him a chance to
do so.
In the case he is running in a loop, it probably means he want to
reproduce a crash or a race inside gdb so we should just go and
run in gdb.
We probably miss a few options to give him more control.
Knowing whether a test failed to run as its prerequisites were not
available, or whether those prerequisites were available and produced
unexpected/incorrect results, is a useful differentiation.
Add support for skipped tests by testing for exit code 77, used through
autotools/piglit/etc to denote a test which detected this and decided to
skip.
