The test apps are intended to be adapted into user code freely,
this relicenses them public domain to make that clear.
Fixes and improvements are of course still welcome.
LICENSE clarifies now that some sources also have a more liberal license,
it was always told in the source itself but now it's summarized.

Since struct lws (wsi) now has his own context pointer,
we were able to remove the need for passing context
almost everywhere in the apis.
In turn, that means there's no real use for context being
passed to every callback; in the rare cases context is
needed user code can get it with lws_get_ctx(wsi)

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 nukes all the oldstyle prefixes except in the compatibility code.
struct libwebsockets becomes struct lws too.
The api docs are updated accordingly as are the READMEs that mention
those apis.

Change all internal uses of rationalized public apis to reflect the
new names.
Theer are a few things that got changed as side effect of search/replace
matches, but these are almost all internal. I added a compatibility define
for the public enum that got renamed.
Theoretically existing code should not notice the difference from these
two patches. And new code will find the new names.

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
under load, writing packet sizes to the socket that are normally fine
can do partial writes, eg asking to write 4096 may only take 2800 of
it and return 2800 from the actual send.
Until now lws assumed that if it was safe to send, it could take any
size buffer, that's not the case under load.
This patch changes lws_write to return the amount actually taken...
that and the meaning of it becomes tricky when dealing with
compressed links, the amount taken and the amount sent differ. Also
there is no way to recover at the moment from a protocol-encoded
frame only being partially accepted... however for http file send
content it can and does recover now.
Small frames don't have to take any care about it but large atomic
sends (> 2K) have been seen to fail under load.

Fixed so that the build options for the CMake project works:
- The test apps used the LWS_NO_EXTENSIONS define, so they needed lws_config.h included when building using CMake.
- Rename some options so that individual test apps can be turned off.
- Separate building the test-client/test-server and compiling the server/client parts into the lib.
- Don't include server or client specific sources into the build if they shouldn't be built.
- Added an error if both client and server parts are excluded at the same time (makes no sense).
- Removed duplicate install targets for the test apps.
- Commented out the WITH_LIBCRYPTO option since it isn't used at the moment.
- Define LWS_DLL and LWS_INTERNAL when websockets_shared is compiled.
- The websocket_shared target compiles to websocket.lib / websocket.dll
(websocket.lib contains the exported functions for websocket.dll, and is
the file that is linked to when a program wants to use the dll)
- The websocket target compiles to websocket_static.lib on windows.
- Replaced any "extern" with "LWS_EXTERN" on libwebsockets.h for proper
DLL function exports.
- Created a LIB_LIST with all the libwebsocket dependencies, instead of
multiple calls to target_link_libraries, only one call is made for both
the static and shared library version. This makes it easy to add other
variants if wanted in the future.
- Added ZLIB as a dependency for the libs, so that the build order will be
correct at all times.
- Added a dependency for the websockets lib to the test apps, so it is
built before them.
- Fixed the test-server-extpoll app to include the emulated_poll, and link
to winsock on Windows.
- Removed the global export of libwebsocket_internal_extensions, and added
a function libwebsocket_get_internal_extensions() that returns it
instead. Using the global would not work with the DLL export on Windows.
*** This patch changes an API all apps use ***
Context creation parameters are getting a bit out of control, this
patch creates a struct to contain them.
All the test apps are updated accordingly.

- Finalized CMake support (tested on windows only so far).
- Uses a generated lws_config.h that is included in
private-libwebsocket to pass defines, only used if CMAKE_BUILD is set.
- Support for SSL on Windows.
- Initial support for CyaSSL replacement of OpenSSL (This has been added
to my older CMake-fork but haven't been tested on this version yet).
- Fixed windows build (see below for details).
- Fixed at least the 32-bit Debug build for the existing Visual Studio
Project. (Not to keen fixing all the others when we have CMake support
anyway (which can generate much better project files)...)
- BUGFIXES:
- handshake.c
- used C99 definition of handshake_0405 function
- libwebsocket.c
- syslog not available on windows, put in ifdefs.
- Fixed previous known crash bug on Windows where WSAPoll in
Ws2_32.dll would not be present, causing the poll function pointer
being set to NULL.
- Uninitialized variable context->listen_service_extraseen would
result in stack overflow because of infinite recursion. Fixed by
initializing in libwebsocket_create_context
- SO_REUSADDR means something different on Windows compared to Unix.
- Setting a socket to nonblocking is done differently on Windows.
(This should probably broken out into a helper function instead)
- lwsl_emit_syslog -> lwsl_emit_stderr on Windows.
- private-libwebsocket.h
- PATH_MAX is not available on Windows, define as MAX_PATH
- Always define LWS_NO_DAEMONIZE on windows.
- Don't define lws_latency as inline that does nothing. inline is not
support by the Microsoft compiler, replaced with an empty define
instead. (It's __inline in MSVC)
- server.c
- Fixed nonblock call on windows
- test-ping.c
- Don't use C99 features (Microsoft compiler does not support it).
- Move non-win32 headers into ifdefs.
- Skip use of sighandler on Windows.
- test-server.c
- ifdef syslog parts on Windows.
The new --without-extensions config flag completely removes all code
and data related to extensions from the build throughout the library
when given.

This adds 05 support, and -v switches on test-client and test-ping
to allow setting their ietf protocol version to 4 or 5.
It also optimizes the masking to us a function pointer, which
takes some conditionals out of the fast path.

I?aki pointed out the dummy host field used in client test and ping
is not valid http. This patch changes it to use the actual host
name and adds an api to collect that from the context cheaply.
