REORG: http: move error codes production and processing to http.c
These error codes and messages are agnostic to the version, even if they are represented as HTTP/1.0 messages. Ultimately they will have to be transformed into internal HTTP messages to be used everywhere. The HTTP/1.1 100 Continue message was turned to an IST and the local copy in the Lua code was removed.
