a496700b3a lws_snprintf
Thanks to Fabrice Gilot for reporting the problem that led to uncovering this.

Due to a misunderstanding of the return value of snprintf (it is not truncated according
to the max size passed in) in several places relying on snprintf to truncate the length
overflows are possible.

This patch wraps snprintf with a new lws_snprintf() which does truncate its length to allow
the buffer limiting scheme to work properly.

All users should update with these fixes.

e35d91a860 per-vhost headers and lwsws conf support
This l;ets you add per-vhost arbitrary headers on served files, eg

     "headers": [{
        "X-Content-Type-Options": "nosniff",
        "X-XSS-Protection": "1; mode=block",
        "x-frame-options": "SAMEORIGIN"
        }],

95fff47a91 client-add-PUSH-http-body-capability
Support HTTP body sending on client connections.

Add demo to test-client.

Run the normal test server, then

$ libwebsockets-test-client http://localhost:7681/formtest -o

It will post the string "hello" to the POST test using application/x-www-form-urlencoded

https://github.com/warmcat/libwebsockets/issues/598

Also ensures any of the Client HTTP transient modes will call back LWS_CALLBACK_CLOSED_CLIENT_HTTP
if they close

f32d25051c ws ping pong on idle connections
This adds a new member to the context creation info struct "ws_ping_pong_interval".

If nonzero, it sets the number of seconds that established ws connections are
allowed to be idle before a PING is forced to be sent.  If zero (the default) then
tracking of idle connection is disabled for backwards compatibility.

Timeouts cover both the period between decision to send the ping and it being
sent (because it needs the socket to become writeable), and the period between
the ping being sent and the PONG coming back.

INFO debug logs are issues when the timeout stuff is operating.

You can test the server side by running the test server hacked to set ws_ping_pong_interval
and debug log mask of 15.  Both the mirror protocol and the server-status protocol are
idle if nothing is happening and will trigger the PING / PONG testing.  (You can also
test using lwsws and /etc/lwsws/conf with "ws-pingpong-secs": "20" in the global section)

For client, run the test client with -n -P 20 for 20s interval.  -n stops the test client
writing using the mirror protocol, so it will be idle and trigger the PING / PONGs.

The timeout interval may be up to +10s late, as lws checks for affected connections every
10s.
