[issue10485] http.server fails when query string contains addition '?' characters

[Glenn Linderman]

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

http.server on Python 3 and CGIHTTPServer on Python 2 both contain the same code with the same bug.  In run_cgi, rest.rfind('?') is used to separate the path from the query string.  However, it should be rest.find('?') as the query string starts with '?' but may also contain '?'.  It is required that '?' not be used in URL path part without escaping.

Apache, for example, separates the following URL:

/testing?foo=bar?&baz=3

into path part /testing  and query string part  foo=bar?&baz=3 but http.server does not.
