1) This makes lwsws run a parent process with the original permissions.
But this process is only able to respond to SIGHUP, it doesn't do anything
else.
2) You can send this parent process a SIGHUP now to cause it to
- close listening sockets in existing lwsws processes
- mark those processes as to exit when the number of active connections
on the falls to zero
- spawn a fresh child process from scratch, using latest configuration
file content, latest plugins, etc. It can now reopen listening sockets
if it chooses to, or open different listen ports or whatever.
Notes:
1) lws_context_destroy() has been split into two pieces... the reason for
the split is the first part closes the per-vhost protocols, but since
they may have created libuv objects in the per-vhost protocol storage,
these cannot be freed until after the loop has been run.
That's the purpose of the second part of the context destruction,
lws_context_destroy2().
For compatibility, if you are not using libuv, the first part calls the
second part. However if you are using libuv, you must now call the
second part from your own main.c after the first part.

This fixes a problem where the check for the existing pw was
skipped when a logged-in user is changing his password.
It's not good but because the user has to be logged in, it only affected
the situation someone changes his password on his logged in session.
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.
