Adds a convenient way to directly get the value of a URL
argument like ...?x=y&v=1, regardless of position in the
parameter list.

This makes it easy for user code to choose the size of the per-thread
buffer used by various things in lws, including file transfer chunking.
Previously it was 4096, if you leave info.pt_serv_buf_size as zero that
is still the default.
With some caveats, you can increase transfer efficiency by increasing it
to, eg, 128KiB, if that makes sense for your memory situation.

Also add lwsws "enable-client-ssl": "1" vhost option to match.
Client cert iclient ssl is not supported in lwsws, if someone wants it, it can be added.

If OOT lws plugins will be packaged as separate projects,
they're going to want to install their plugins somewhere
that makes sense for the package instead of one big lws
plugin dir.
This patch changes info to have a const char ** to a NULL
terminated array of directories it should search for
plugins. lwsws knows about this and you can add to the
dir array using config fragments like
{
"global": {
"plugin-dir": "/usr/local/share/coherent-timeline/plugins"
}
}
if the config fragment in /etc/lwsws/conf.d/ is also managed by the
package with the plugin, it can very cleanly add and remove itself
from lwsws based on package install status.

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.

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.

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.

After discussion here
https://libwebsockets.org/pipermail/libwebsockets/2016-April/002268.html
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.

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.

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.
