There's no reason to not have the mounts linked list init also in the info
struct, rather than provide as a paramater to lws_create_vhost(). Now
is a good time to normalize that since this api only exists in master.
This also allows oldstyle "do everything at context creation time in one
vhost" guys to leverage mounts.
Also there's no reason the mounts linked-list pointer and all uses in lws
are non-const, so make them all explicitly const *.
Update the info struct docs to clarify which members are used when creating
a vhost and which for context creation.

This demonstrates how to do a 303 redirect on POST and provide
the results there, in both libwebsockets-test-server and the
plugin version.

Ah a real bug... well done coverity, that could have been nasty.
readlink unusually doesn't NUL terminate the result... take care about it.

This allows mounts to define the caching policy of the files inside them.
Support is added in lwsws for controlling it from the config files.
The api for serializing a mount struct opaquely is removed and lws_http_mount struct
made public... it was getting out of control trying to hide the options.

Even if no ah available, we will be on the ah waiting list and get triggered
when one is freed and we're next in line.

This trades off a couple of wsi pointers for vastly increased speed
for the callback when writeable "all protocol" variants when there
are many kinds of wsi active.

Chrome deals with it without on desktop, but Android chrome
waits for the connection to time out before actioning the
redirect, since it feels there might be html payload coming.

This adds the ability to store apache-compatible logs to a file given at
vhost-creation time.
lwsws conf can set it per-vhost using "access-log": "<filepath>"
The feature defaults to disabled at cmake, it can be set independently but
LWS_WITH_LWSWS set it on.

This
1) fixes the vhost changes on master
2) works around the ah pool changes
3) fixes some other build problems that appeared
4) hacks out physical flow control for internal streams
5) updates the advertised protocol to h2 needed by, eg, chrome 51
That gets it able to serve small (<4K, ie, one packet) files over http2

This adds support for dynamically loaded plugins at runtime, which
can expose their own protocols or extensions transparently.
With these changes lwsws defaults to OFF in cmake, and if enabled it
automatically enables plugins and libuv support.

This patch splits out some lws_context members into a new lws_vhost struct.
- ssl state and options per vhost
- SSL_CTX for serving and client per vhost
- protocols[] per vhost
- extensions[] per vhost
lws_context maintains a linked list of lws_vhosts.
The same lws_context_creation_info struct is used to regulate both the
context creation and to create vhosts: for backward compatibility if you
didn't provide the new LWS_SERVER_OPTION_EXPLICIT_VHOSTS option, then
a default vhost is created at context creation time using the same info
data as the context itself.
If you will have multiple vhosts though, you should give the
LWS_SERVER_OPTION_EXPLICIT_VHOSTS option at context creation time,
create the context first and then the vhosts afterwards using
lws_create_vhost(contest, &info);
Although there is a lot of housekeeping to implement this change, there
is almost no additional overhead if you don't use multiple vhosts and
very little api impact (no changes to test apps).

Adds lws_check_opt() to regularize multibit flag checking.
There's a new context creation flag LWS_SERVER_OPTION_DO_SSL_GLOBAL_INIT,
this is included automatically if you give any other SSL-related option flag.
If you give no SSL-related option flag, nor this one directly, then even
though SSL support may be compiled in, it is never initialized nor used for the
whole lifetime of the lws context.
Conversely in order to prepare the context to use SSL, even though, eg, you
are not listening on SSL but will use SSL client connections later, you can
give this flag explicitly to make sure SSL is initialized.

If you enable -DLWS_WITH_HTTP_PROXY=1 at cmake, the test server has a
new URI path http://localhost:7681/proxytest If you visit here, a client
connection to http://example.com:80 is spawned, and the results piped on
to your original connection.
Also with LWS_WITH_HTTP_PROXY enabled at cmake, lws wants to link to an
additional library, "libhubbub". This allows lws to do html rewriting on the
fly, adjusting proxied urls in a lightweight and fast way.
Move the socket bind to interface code out of server into
libwebsockets.c and make a private api for it.

Originally this was alright in wsi->u.hdr, because ah implied header
processing. But since we allowed ah to be held across http
keep-alive transactions if we saw we had more header data, it means
we were trying to read this union member out of scope after it had
transitioned.
Moving the more_rx_waiting member to be a 1-bit bifield in the wsi
solves it and lets us check the state any time later at http
transaction completion.
