[issue10484] http.server.is_cgi fails to handle CGI URLs containing PATH_INFO

[Glenn Linderman]

New submission from Glenn Linderman <v+python at g.nevcal.com>:

is_cgi doesn't properly handle PATH_INFO parts of the path.  The Python2.x CGIHTTPServer.py had this right, but the introduction and use of _url_collapse_path_split broke it.

_url_collapse_path_split splits the URL into a two parts, the second part is guaranteed to be a single path component, and the first part is the rest.  However, URLs such as

/cgi-bin/foo.exe/this/is/PATH_INFO/parameters

can and do want to exist, but the code in is_cgi will never properly detect that /cgi-bin/foo.exe is the appropriate executable, and the rest should be PATH_INFO.

This used to work correctly in the precedecessor CGIHTTPServer.py code in Python 2.6, so is a regression.
