rxrpc: Turn connection #defines into enums and put outside struct def
Turn the connection event and state #define lists into enums and move outside of the struct definition. Whilst we're at it, change _SERVER to _SERVICE in those identifiers and add EV_ into the event name to distinguish them from flags and states. Also add a symbol indicating the number of states and use that in the state text array. Signed-off-by: David Howells <dhowells@redhat.com>
