MINOR: mux-h1: Be able to set custom status code on parsing error

Browse Source 
When a parsing error is triggered, the status code may be customized by
setting H1C .errcode field. By default a 400-Bad-Request is returned. The
function h1_handle_bad_req() has been renamed to h1_handle_parsing_error()
to be more generic.
