Make hgweb.staticfile() more secure and portable.
Without this, files in directories next to the static directory starting
with 'static' could be retrieved, e.g. with '../static.private/foo'.
Additionally staticfile now generates platform specific pathnames from
the /-separated paths given in the URL.
Illegal file names (e.g. containing %00) now yield a sane error message.
