DISPATCH-1354: Annotation processing performance improvements
Message annotation processing on received messages stages key names
byte by byte into a flat buffer and then uses strcmp to check them.
Easy improvements are:
* Use name in raw buffer if it does not cross a buffer boundary
* If name crosses a boundary then use memmoves to get the name in chunks
* Check the name prefix only once and then check variable parts of name strings
* Don't create unnecessary qd_iterators and qd_parsed_fields
* Don't check names whose lengths differ from the given keys
> Interrouter annotation processing uses slow methods
