QPID-3883: Using application headers in messages causes a very large slowdown

Change Exchange route interface not to require a fieldtable
- Exchanges that actually use the fieldtable for routing
  need to extract it directly from the message themselves.
  This avoids the need to extract the fieldtable from the message
  unnecessarily.
