Code cleanup
Description:
Added some comments about the thread-specific memory for the error and
function stacks.
Changed H5close() to not use the function stack (since it causes it to
be re-enabled after shutting it down)
Changed thread-safe semaphore code to not use dynamicly allocated memory.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Linux 2.4
Too minor to require h5committest
