* bx: Small platform detection/usage improvements
* Use BX_PLATFORM_POSIX where needed
The semaphone implementation already uses BX_PLATFORM_POSIX to include
<pthread.h> on all the POSIX platforms; do the same also in other places
for consistency. This is done also for <sched.h>, which is a POSIX API,
and sched_yield() from it is already guarded by BX_PLATFORM_POSIX.
* Drop support for GNU libc older than 2.12
glibc 2.12 was released on 2010, and at this point any supported Linux
distro has that version or way greather than that.

* bx: fix <pthread/pthread.h> include on Hurd
<pthread/pthread.h> does not exist, the standard <pthread.h> does exist
so switch to it.
* osd/modules/file: use dirent::d_type on any GNU libc platform
This BSD extension is provided by GNU libc, so enable its usage with
that C library.
* osd/modules/file: use <pty.h> on any GNU libc platform
openpty() is implemented by GNU libc for all the OSes, so include
<pty.h> when using that C library.
* osd/modules/file: cast dirent::d_name to const char* before using it
According to POSIX [1], the type of dirent::d_name is loosely defined
as "char d_name[]", as array with an undefined size. In particular, few
ways are seen in the wild:
(a) "char d_name[size]", i.e. as proper array with a full size
(b) "char d_name[1]"/"char d_name[0]", i.e. as C flexible arrays
Regardless of its type, dirent::d_name is used as if it was a classic
const char *, i.e. as pointer to a null-terminated string.
util::string_format() uses C++ templates to collect all the arguments,
and thus it will use the actual type of dirent::d_name. In case of (a)
there is no issue, however for (b) the result is that only the first
character is used.
To ensure that dirent::d_name is fully used, explicitly cast it to
const char * before passing it to util::string_format(), so the whole
string is used.

* Sync with bgfx upstream revision b91d0b6
* Sync with bx upstream revision d60912b
* Sync with bimg upstream revision bd81f60
* Add astc-codec decoder
* Rename VertexDecl to VertexLayout
* Rename UniformType enum Int1 to Sampler.
* Add NVN stub
* Fix unused-const-variable error on macOS
* Drop redundant explicit language parameters
buildoptions_cpp are only applied to c++ files and buildoptions_objcpp are only
applied to objective c++ files. As such, hardcoding -x offers no benefit while
preventing overrides (such as one needed by 3rdparty/bgfx/src/renderer_vk.cpp on
macOS) from working.
* Re-introduce -x c++ in places where C code is compiled as C++ to prevent clang from throwing a warning
* Build bgfx as Objective-C++ on macOS
It is needed due to included headers
* Enable Direct3D12 and Vulkan bgfx rendering backends
* Enable building of spirv shaders
* Properly escape /c in cmd call
* Comment out dx12 bgfx renderer
* Honor VERBOSE setting during shaders build
* Only invert hlsl shader XYZ_TO_sRGB matrix for opengl
* Add spirv shaders
* OpenGL ES needs transposed matrix too
* Metal needs transposed matrix as well
