Somehow the last set of tests added got converted to DOS text
(CRLF line terminators). Change them back

John,
thanks a lot for taking care of the new tests.
By some reason, the spec file was not included in the patch. This
patch is needed to prevent the rpm build from finding installed
but unpackaged files.

Do a better job of explaining that the backfire kernel module may need
building in the sendme program.

Add a .gitignore file in the backfire directory for generated files
that are created when making the kernel module.

from signaltest - because it doesn't have the fix that check_privs in
cyclictest has - to return the sched_priority to 0
This is a good example of why common functions should be put into libraries -
so all programs benefit from fixes.

This commit adds some output then the -b option is used to break on
exceeding a threshold. the thread id of the thread that exceeded the
threshold is printed for use when looking at the trace log.

Add a second newline to the "Low thread priority" display line
so that updating number of inversions doesn't overwrite it.

When using pthread_barrier_wait, it is important that barriers are called
the correct number of times. That is - the same number given as the count
when initializing the barrier.
There was a do-while loop around elevate_barrier in the med priority thread.
On most machines, it actually never looped.
On threads with enough processors (nehelam for example), there was a racy
situation in which the high priority thread could come out of the finish
barrier, and before it could set high_has_run = 0, the medium priority
thread would test the value and call the elevate barrier an extra time.
This patch removes the bogus loop and related state variables and fixes
the hang.

- Check whether quiet is set, before taking shutdown_mtx
- Add quiet to the help menu.
- Remove unused "signal" from struct options

- Use a pthread_mutex_t for the global variable shutdown.
- Remove the volatile qualifier from shutdown. (Since the original author
probably simply meant the variable should be atomic which we effectively
get through the mutex.
