CLEANUP: http-htx: Rename http_error structure into http_error_msg

Browse Source 
The structure owns an error message, most of time loaded from a file, and
converted to HTX. It is created when an errorfile or errorloc directive is
parsed. It is renamed to avoid ambiguities with http_reply structure.
