Router routing table management. Table route hashes. Status codes changed.

We now manage routing table actions using dedicated functions run on
either registry or services in the registry.

Routing table now uses Route.Hash() instead of maintaining its own hash
struct filed which previously performed these operations.

Various names of variables have been changed to make them more concise.
