[PATCH] gitweb: Make use of $PATH_INFO for project parameter

Allow to have project name in the path part of URL, just after the name of
script. For example instead of gitweb.cgi?p=git.git you can write
gitweb.cgi/git.git or gitweb.cgi/git.git/

Not used in URLs inside gitweb; it means that the above alternate syntax
must be generated by hand, at least for now.

Side effect: project name parameter is now stripped of leading and
trailing slash before validation.
