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

scandir usage in
- lwsws conf.c
- lws plugin support
and
- lws plugin apis for dl
are converted to us libuv apis so they can work cross-platform easily.
lws itself remains not requiring libuv, although it's an option.
- LWS_WITH_LWSWS
- LWS_WITH_PLUGINS
now force LWS_WITH_LIBUV if selected... both of these are new features
only in master atm and both are off by default in CMake.
There's a complication libuv can be too old to offer the necessary apis,
this is the case in Travis Trusty instance. In that case, UV_VERSION_MAJOR ==0,
then the unix-only plugin implementation is used instead.

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.

Add a test html button that will send 9KB of junk to confirm it
https://github.com/warmcat/libwebsockets/issues/480
permessage-deflate now checks the protocol rx buffer size for being
>=128, if not, permessage-deflate is disabled on that connection.
If it is >=128 but less than the zlib decompress buffer size, the
zlib decompress buffer size for that connection is reduced to the
nearest power of two of the protocol rx buf size.
To test this, dumb_increment is left violating the >= 128 rx buffer
size and permessage-deflte can be seen to be disabled on his
connections in the test html.

Fix building libwebsockets with the musl C libary.
<sys/cdefs.h> is an internal glibc header and should be avoided in user code.
__P() was used for compatibility with some old K&R C compilers, when there were
no prototypes (which were introduced to C with C89). As supporting legacy
non-ANSI compilers is nowadays not necessary anymore get rid of the unnecessary
function prototype using __P().
polarssl is the old name for mbedtls. Unfortunately the two are confused in eg,
Fedora. For our purposes, polarssl or mbedtls < 2.0 has includes in
/usr/include/polarssl and polarssl_ apis and we call that "polarssl".
polarssl or mbedtls >=2.0 has includes in /usr/include/mbedtls and mbedtls_ apis,
we call that "mbedtls".
This has to be spelled out clearly because eg Fedora has a package "mbedtls" which
is 1.3.x and has the polarssl_ apis and include path. We will deal with that as
"polarssl" despite the package name then.
This patch lets you use LWS_USE_POLARSSL or LWS_USE_MBEDTLS and set the include and
library path like this
cmake .. -DLWS_USE_POLARSSL=1 -DLWS_POLARSSL_INCLUDE_DIRS=/usr/include -DLWS_POLARSSL_LIBRARIES=/usr/lib64/libmbedtls.so.9
This patch adds the cmake support and adapts [private-]libwebsockets.h but doesn't
modify the apis in ssl[-*].c yet.

Most of ssl.c is under a #ifdef for client or server disabled...
let's get rid of it and have CMake just build the appropriate
files

This makes a start on the LibWebSockets WebServer.
The app cmake build support and JSON config parsing are implemented and
the app can start, create the vhosts, listen and serve file:// mounts on
them.

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).

This takes tha callback and binds the lws_context to the SSL_CTX so we can
get the lws_context in the callback.
It just logs the incoming hostname atm.

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.
