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.

Even for endpoints that currently do not need options (such as
Subsz and Varz), I added some options and a return of error so that
we don't break the API if we ever need to add options for those.
In tests, replaced all code doing http.Get, etc.. with a readBody
helper function.
Combine server functions and monitor handler tests in one test
with a for loop to try both modes on a given test.
Still need to add Connz.
Fixes#612 by adding a new Varz method to the Server. This can be used
by processes embedding gnatsd to access the Varz struct without relying
on the HTTP API. This starts with just Varz but the same pattern could
be expanded to other monitoring APIs in the future.
If server requires TLS and clients are connecting, and a Connz
request is made while clients are still in TLS Handshake, the
call to tls.Conn.ConnectionState() would block for the duration
of the handshake. This would cause the overall http request to
take too long.
We will now not try to gather TLSVersion and TLSCipher from a
client that is still in TLS handshake.
Resolves#600
gnatsd currently uses a global logger. This can cause some problems
(especially around the config-reload work), but global variables are
also just an anti-pattern in general. The current behavior is
particularly surprising because the global logger is configured through
calls to the Server.
This addresses issue #500 by removing the global logger and making it a
field on Server.
Fixes#304
Changes the non-ASCII curly quotes in the HTML to use the regular ASCII double quotes. Also adds a test to check for the existence of non-ASCII characters in that same HTML.
