Specifically this is to support distributed tracking of number of account connections across clusters.
Gateways may not work yet based on attempts to only generate payloads when we know there is outside interest.

- If/when splitting buffer to pass to queueOutbound(), it has to
be include full protocol.
- Fix counting of total queue subs
- Fix tests
- Send RS- if no plain sub interest even if there is queue sub
interest.
- Removed a one-liner function

- Solve RS+ with wildcards
- Solve issue with messages not send to remote gateways queue subs
if there was a qsub on local server.
- Made rcache a perAccountCache since it is now used by routes and
gateways
- Order outbound gateways only on RTT updates
- Print a server's gateway name on startup
- Augment/add some tests
- Update TLS handling: when connecting, use hostname for ServerName
if url is not IP, otherwise use a hostname that we saved when
parsing/adding URLs for the remote gateway.
- Send big buffer in chunks if needed.
- Add caching for qsubs match

Start the lame duck mode in a go routine in the signal handler
because I think we want to be able to shutdown the server while
in that mode.
Kept the closing as a loop in the lameDuckMode() function (did
not use a timer).

When receiving SIGUSR2 signal (or -sl ldm) the server stops
accepting new clients, closes routes connections and spread the
closing of client connections based on a config lame duck duration
(default is 30sec). This will help preventing a storm of client
reconnect when a server needs to be shutdown.

- Use stack buffers
- Ensure that buffer size is no greater than 90% of max_pending
- Added test with low max_pending

- Removed un-needed lock/unlock
- Buffer SUBs/UNSUBs protocols and ensure flushing when buffer
gets to a certain size (otherwise route would get disconnected
with high number of subscriptions)
