Build tools are updated to support building with Visual Studion 2019 toolset ClangCL (LLVM clang-cl):
- In CMake builds, use of unsupported option "-std=c++0x" is avoided
- Tool genconf recognizes availability of ClangCL toolset and proposes it in the list
- Tool genproj recognizes new compiler specification VCVER=vclang and generates VS 2019 projects for it
Note that vclang configuration puts binaries to folder "vc14" as it is compatible with vc14 CRT.
Code is updated to build with Clang for Windows without errors and warnings:
- In BVH classes, pure virtual destructors are replaced by empty ones, to avoid bogus compiler warning
- In .lex files, pragmas are added to disable warnings in parser code
- In OSD, signature of function _osd_wnt_set_error() is corrected to avoid warning on incorrect use of va_args (undefined behavior)
- In OSD_Host, OSD_Parallel_TBB, warnings on usage of deprecated function are disabled
- In Quantity_ColorRGBA and ViewerTest_CmdParser, incorrect use of predefined macro __FUNCTION__ assuming it was a string literal is avoided
- In Standard_Macro.hxx, code is reordered to handle Clang for Windows appropriately
- In AdvApp2Var_SysBase.hxx, inclusion of obsolete (MSVC-specific) header file is replaced by Standard_TypeDef.hxx
- In Standard_ErrorHandler.hxx, empty statements added to avoid warning on unused class fields
- In IVtkDraw and ViewerTest, interface is corrected to use actual type avoiding unnecessary type casts
Off-topic: corrections of some errors (uninitialized class fields) reported by VS Code Analysis in TKernel
Handled __EMSCRIPTEN__ macros to:
- Workaround atomics (__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 is undefined, but GCC atomics are provided).
- Suppress non-standard header <sys/signal.h> warning.
- Return OSD_LinuxREDHAT.
- Avoid inclusion of XLib headers.
- Skip fontconfig library.
- Enable EGL+GLES path (translated by Emscripten into WebGL).
- Skip eglCreatePbufferSurface() not implemented by Emscripten EGL.

by defining Light properties accessors as macros instead of functions
('[]' : Index expression must be constant).

depth-stencil attachment on WebGL 1.0 + GL_WEBGL_depth_texture extension.

to handle use case, when Immediate Layer is drawn directly into window buffer,
which is not sRGB-ready.

"endl" manipulator for Message_Messenger is renamed to "Message_EndLine".
The following entities from std namespace are now used

std::cin,std::endl,std::ends,std::flush,std::setw,std::setprecision,
std::hex,std::dec.
RWMesh_CafReader - added new interface class for common workflow for reading mesh data files into XDE document.

(like front/left) for Z-up and Y-up conventions.
V3d_View::SetProj() now accepts argument for asking Y-up instead of Z-up.

CMake scripts - the option -std=c++0x has been replaced by -std=gnu++0x
for mingw to allow extensions (like _wfopen() and others).
The minimum Windows version has been set to _WIN32_WINNT=0x0501.
Invalid options "-z defs" and "-lm" have been dropped for mingw.
Flag --export-all-symbols has been added to CMAKE_SHARED_LINKER_FLAGS
to workaround missing vtable symbols when using mingw.
FreeType is now linked explicitly on Windows.
Draw::Load() - "lib" suffix is now prepended on mingw as well.
Drop redundant declaration of _TINT from OSD_WNT_1.hxx.
NCollection_UtfString::FromLocale() - platform-specific code has been moved to .cxx file.
Draw_BasicCommands - fixed incorrect mingw64 version macros.
