Added to WSF_REQUEST

Browse Source 
- raw_header_data: like meta_string_variable
  - read_input_data_into (buf: STRING)
  - is_content_type_accepted (a_content_type: READABLE_STRING_GENERAL): BOOLEAN
Changed raw_input_data to return IMMUTABLE_STRING_8
Added WSF_METHOD_NOT_ALLOWED_RESPONSE
Added WSF_TRACE_RESPONSE to respond TRACE request
Now Not_found response return html content if the client accepts, other text/plain
Implemented TRACE response, and Method not allowed as implementation of WSF_ROUTED_SERVICE.execute_default
