Add a simple microbenchmark framework, packaging, and sample tests.

Add a simple microbenchmark framework, packaging, and sample tests.

I have no idea if this is useful, but it works for me and might be useful if you have specific functions to test.  No effort has been made to make it pretty or ensure statistical relevance.

Any thoughts, review, etc are appreciated.  I just needed something I could hack
on quickly and pulled this together. (With some cleanup before mailing this cl
:)

Thanks! Fixed.

I'll submit this then and investigate some of the open source alternatives that
have been suggested (like libmicro).

However, for a full suite, we might just stuck with autotest+unixbench :)s
