Deal with the performance problem in parse_uri_components(). This new

version is over two orders of magnitude faster based on timing trials
requesting the test page from mod_test_util_uri.  It's 50% faster overall
when doing a zb /index.html with the default index.html.

I'm still resiting the urge to hardcode i386 assembly language with
a C fallback for the rest of the world ;)
