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.

This allows you to do
make DEBUG=0
which changes CFLAGS from -Wall -Wno-nonnull -O2
to -Wall -Wno-nonnull -O0 -g

Subject: [PATCH] Add tags and TAGS to .gitignore
Add tags and TAGS to .gitignore, to prepare for a make tags option
"-" must be escaped ("\-") to be interpreted as minus, otherwise they
might be rendered as hyphen which makes it impossible to search for or
to cut'n'paste.
See http://lintian.debian.org/tags/hyphen-used-as-minus-sign.html for a
detailed explanation.

Note: the previous one sucked rockz, please try this one instead.
When running on a machine with not enough bandwidth it can be helpful to
only update the status when a new max is hit.
