[gPXE] patch: uriWithDecodedUserInfo, this time by git format-patch.

[Stefan Hajnoczi]

Please resend as an attachment.  The whitespace has been mangled and
the patch doesn't apply.

Thanks for adding test cases.  Please leave the tests without a
username:password and append the new test cases on the end.  That way
URIs without username:password remain tested.
