[boost] [thread] null_mutex

Looking through the archives, a number of requests have been made for a
null_mutex, but none exist.  Probably because of the chance of trouble
when used in conjunction with a condition variable.  However, I have
need for one (and it looks like others do as well, with a simple google
search).  Attached, are two files, each representing the output of
running cvs diff on my local CVS repository (which is the official 1.32
release).

diff.txt is the result of running:
        cvs -q diff
diff-c.txt is the result of running:
        cvs -q diff -c

I'd appreciate any feedback, and also consideration to add something
like this to Boost.Thread.
