Check the allowed characters for ":method" (see RFC 7230, section 3.2.6) and ":path". For ":path", the space and tab characters are now forbidden, but other special characters are still allowed for compatibility reasons. Update genvchartbl.py so that it generates the same table as in the code. Fixes #1611
