* alBufferData instead of alBufferDataStatic for small audio file on Apple (#19227)
* changes AudioCache to use alBufferData instead of alBufferDataStatic
(also makes test 19 faster to trigger openal bugs faster)
The original problem: CrashIfClientProvidedBogusAudioBufferList
https://github.com/cocos2d/cocos2d-x/issues/18948
is not happening anymore, but there's still a not very frequent issue
that makes OpenAL crash with a call stack like this.
AudioCache::readDataTask > alBufferData > CleanUpDeadBufferList
It happes more frequently when the device is "cold", which means after
half an hour of not using the device (locked).
I could not find the actual source code for iOS OpenAL, so I used the
macOS versions:
https://opensource.apple.com/source/OpenAL/OpenAL-48.7/Source/OpenAL/oalImp.cpp.auto.html
They seem to use CAGuard.h to make sure the dead buffer list
has no threading issues. I'm worried because the CAGuard code I found
has macos and win32 define but no iOS, so I'm not sure. I guess the
iOS version is different and has the guard.
I could not find a place in the code that's unprotected by the locks
except the InitializeBufferMap() which should not be called more than
once from cocos, and there's a workaround in AudioEngine-impl for it.
I reduced the occurence of the CleanUpDeadBufferList crash by moving
the guard in ~AudioCache to cover the alDeleteBuffers call.

2. Uses only one libwebsockets context, multiple wsi instances to avoid multi-thread issues
3. Uses lws_create_vhost to create multiple virtual host, different protocols works
* Adds openssl include path to xcode project configuration.
* mac doesn’t depend on curl
* ca file path should be full path.
* More bug fixes like which in https://github.com/cocos2d/cocos2d-x/pull/6986
* Remove curl dependence for mac
* Updates Andorid.mk
* [win32] Adds wss support for win32, and updates openssl, libcurl, libwebsockets libraries.
* Updates external/config.json to 118.
* [win32] Updates cocos/2d/libcocos2d.vcxproj to fix compilation error while building in release mode.
* Linux support websocket ssl connection.

* Use the VS 2015 libraries for MSVC 14
When compiling with MSVC 14, the linker cannot find `libpng-2015.lib`, `libtiff-2015.lib`, `libjpeg-2015.lib` and `libglfw-2015.lib`. This commit fixes that problem
* Remove the -2015 suffix from the non-MSVC 14 part on libchipmunk
* Fix Linux compiler errors
Check If we are on Windows then check for VS 2015.
- Added c++_shared (LLVM) to Android toolchain options. Fixed AndroidNdkGdb.cmake.
- Fixed includes when not using prebuilt libs. Added option to use sources in external when not using prebuilt libs.
- Added option in CMake to be able build Box2D without using it as physics library in cocos2d-x (similar to what is done in the Visual Studio solution).
Now build system looks more maintanable.
I test with mac, going to test with other platforms.
* All prebuilt libs config moved to
cmake/Modules/CocosUsePrebuiltLibs.cmake
* Wrap plain find_package to our cocos_find_package. It will not try to
call find_package if USE_PREBUILT_LIBS and <pkg>_FOUND set to true.
* Other small fixes.
1. Add cmake module for finding minizip in system
2. Check that system installed minizip recent enough for us
3. As right minizip exists only for MSYS2 (mingw), use our embedded version on all other platforms
4. Correctly include minizip as <minizip/unzip.h> if it is found from system (make it compatible to current build system, so by default all should stay same)
5. Remove one unused include of unzip.h
* should be included as simple "tinyxml2.h", but on some files was "tinyxml2/tinyxml2.h", replace this.
* Add cmake/Modules/FindTinyXML2.cmake
* As tinyxml2 for now has not prebuilt, instead sources included, add their as subdirectory if USE_PREBUILT_LIBS
* cmake/Modules/FindChipmunk.cmake now can find prebuilt chipmunk libs
* follow USE_CHIPMUNK variable (although at the moment cocos can't build without chipmunk)
* come cleanups and formatting
* introduce config variable USE_PREBUILT_LIBS (default: ON). When OFF, cmake will not use prebuilt libs, only try find system installed libraries.
* FindGLFW3.cmake now search our prebuilt library (if USE_PREBULT_LIBS)
* FindFreetype.cmake also
This and next changes should simplify our CMakeLists.txt files and USE_PREBUILT_LIBS config allow external package developers to integrate cocos to their packaging system.
