This gets the libuv stuff plumbed in and working.
Currently it's only workable for some service thread, and there
is an isolated valgrind problem left

libuv wants to sign off on all libuv 'handles' that will close, and
callback to do the close confirmation asynchronously. The wsi close function
is adapted when libuv is in use to work with libuv accordingly and exit the uv
loop the number of remaining wsi is zero.

This just lets you build lws 1.6 without pthreads if your OS / toolchain
makes that possible, in the case you don't build the test apps
(libwebsockets-test-server-pthreads needs it)

This adds support for multithreaded service to lws without adding any
threading or locking code in the library.
At context creation time you can request split the service part of the
context into n service domains, which are load-balanced so that the most
idle one gets the next listen socket accept.
There's a single listen socket on one port still.
User code may then spawn n threads doing n service loops / poll()s
simultaneously. Locking is only required (I think) in the existing
FD lock callbacks already handled by the pthreads server example,
and that locking takes place in user code. So the library remains
completely agnostic about the threading / locking scheme.
And by default, it's completely compatible with one service thread
so no changes are required by people uninterested in multithreaded
service.
However for people interested in extremely lightweight mass http[s]/
ws[s] service with minimum provisioning, the library can now do
everything out of the box.
To test it, just try
$ libwebsockets-test-server-pthreads -j 8
where -j controls the number of service threads

Sort the list of source files before passing them to the kernel-doc
script so that it always outputs the discovered functions and
structures in the same order.
This is the initial push of a fuzzing proxy we will use for testing lws.
Run libwebsockets-test-fuzxy and the test server if it's local.
Then run the test client with
http_proxy=localhost:8880 libwebsockets-test-client localhost (or whatever)
Right now he only fuzzes one thing but he is operational as a proxy.
If we enabled libev support, generate a test server variant that uses it.
Libev has sets its face against fixing its warnings and says -Werror is
"stupid". So we work around it for the problems their apis cause in
Travis.

It saves us ~4KB of lwsl_info / _debug etc strings.
The test app comes in at 114KB then, including 19KB of html, png and ico assets.

Extend the cleanout caused by wsi having a context pointer
into the public api.
There's no point keeping the 1.5 compatibility work,
we have changed the api in several places and
rebuilt wasn't going to be enough a while ago.

This changeset adds a few preprocessor macros to lws_config.h to allow
a user of libwebsockets to determine at compile time which version of
lws they are compiling against.
This exposes the already existing LWS_LIBRARY_VERSION_MAJOR and _MINOR
values, and adds LWS_LIBRARY_VERSION_PATCH. This suggests that future
minor bugfix release versions of lws would be e.g. 1.6.0 -> 1.6.1 rather
than the style used previously: 1.2 -> 1.21.
The way this is currently set up means new minor revisions (with
_PATCH==0) always end with .0 but I could change this if preferred.
The most important addition is LWS_LIBRARY_VERSION_NUMBER, which
produces a number of the form 1005001 for version 1.5.1 - i.e. each part
major, minor, patch can extend from 0-999. This macro allows a very easy
compile time comparison of version numbers.
This is off by default, use
-D LWS_WITH_OLD_API_WRAPPERS=1
on cmake to get the old api names exported from the library as wrappers
around the new api names.
This allows the library to continue to be compatible with apps that are
not rebuilt with the new libwebsockets.h api compatibility defines.

You have to explicitly disable LWS_WITHOUT_BUILTIN_SHA1 Cmake option
alomg with SSL to disable SSL
cmake .. -DLWS_WITH_SSL=OFF -DLWS_WITHOUT_BUILTIN_SHA1=OFF
This makes that implicit with disabling SSL.

Improvemed patches to address travis and appveyor build errors
Reduced WINVER and _WIN32_WINNT to 0x0501 to be less restrictive
Refined CMakeLists.txt to allow for normal Windows and MinGW-specific OpenSSL certificate generation
Simplified include path to gettimeofday.h
Removed unnecessary list(APPEND LWS_LIBRARIES zlib_internal) export
Added back #include <windows.h> to gettimeofday.c to fix build for normal Windows
Made sure that pollfd gets defined on libwebsockets side when _WIN32_WINNT < 0x0600
Made sure that WINVER and _WIN32_WINNT don't get overridden by libwebsockets headers when already set to something greater than 0x0501
Added missing declaration of WSAPoll function for WINVER < 0x0600 in libwebsockets.h, eliminated invalid usages of pollfd instead of libwebsocket_pollfd in test-server.c
Cleaned up duplicate content in gettimeofday.c, removed header inclusions from gettimeofday.h and fixed include order in test-echo.c, test-ping.c and test-server.c to enable build with normal Windows and MinGW
Re-enabled debug_level in test-echo.c and made sure that the call to lws_set_log_level() is also active under Windows (just like in test-server.c); replaced all WIN32 occurrences by _WIN32 in test-echo.c, test-ping.c, and test-server.c
Removed build-msys.sh and added new section about how to build libwebsockets using MinGW to README.build.md
Commit 173e9c4e made LWS_SEND_BUFFER_SIZE a multiple of a certain
value returned by _LWS_PAD_SIZE macro. This macro expanded to
"sizeof(void *)" on non-x86_64 architectures, which made it
unsuitable to use LWS_SEND_BUFFER_SIZE in preprocessor #if
expressions in the library user code.
This patch preserves the padding logic since commit 173e9c4e but
makes it more preprocessor-friendly for applications using
libwebsockets by setting _LWS_PAD_SIZE to the size of "void *"
determined by cmake when libwebsockets is configured for the
target platform.
