- 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

This will allow to signal multiple servers at once to go in
that mode and not have their client reconnect to one of the
servers in the group.

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.

- Config reload tests have been modified to not rely on symlink.
- Close logger on shutdown (for Windows tests cleanup)

Needed to use filepath, not path for Join/Base in order for that
to work. Tests were actually failing on Windows and now they pass.

The added option writes a file in the specified directory called <exename>_<pid>.ports which
contains a JSON representation of ports that the gnatsd has opened.
This change is intended to facilitate testing by having ports be specified with a -1, so
they are auto assigned and allow tests to locate and connect to the launched gnatsd(s).
The one for route was already changed. Changing the one for
client handshake and TLS timeout.

When a route connection is created, the server will keep track
of the client structure in a special map until the route protocol
completes. This is meant so that if the server is shutdown before
the route is registered in routes map, the server can kick out
the connection's readLoop.
The route connection was correctly removed on success, but was
not for route connections that were not registered and dropped.
This was not causing any issue, but for correctness, doing the
removal now when server removes a route connection.

I noticed that when running the test suite, there would be a file
server/log1.txt left. This file is created by one of the config
reload test. Running this test individually was doing the proper
cleanup. I noticed that the Signal test that was checking
that files could be rotated was causing this side effect.
It turns out that none of the config reload tests were disabling
the signal handler (NoSigs=true), and since the go routine would
be left running, running the TestSignalToReOpenLogFile() test
would interact with an already finished test.
I put a thread dump in handleSignals() to track all tests that
were causing this function to start the go routine because NoSigs
was not set to true. I fixed all those tests. At this time, there
are only 2 tests that need to start the signal handler.
I have also fixed the code so that the signal handler routine select
on a server quitCh that is closed on shutdown so that this go routine
exit and is waiting on using the grWG wait group.
This is the result of flapping tests in go-nats that were caused
by a defect (see PR https://github.com/nats-io/go-nats/pull/348).
However, during debugging, I realize that there were also things
that were not quite right in the server side. This change should
make it the notification of cluster topology changes to clients
more robust.
