secchan: Don't let queued packets exhaust memory.

The ofproto code was queuing OpenFlow messages to connections without
limiting the maximum number that could be queued at a time.  Thus, the
backlog could grow without bound and exhaust all system memory.

This commit introduces a cap on the maximum number of queued messages
in two different categories: packet-in messages and replies to OpenFlow
requests.
