* Check that m_display is not null to prevent crash
https://mametesters.org/view.php?id=7372
* Probe method to check if X11 is actually being used
As per: https://github.com/mamedev/mame/pull/5725#issuecomment-540004475 this will help MAME verify X11 has no inputs when X11 is not actually being used (e.g. on RetroPie where SDL display is RPI).
* Fix issue where a lightgun with no name would return nullptr
As suggested by https://github.com/mamedev/mame/pull/5725#issuecomment-539914514 , a bug in create_lightgun_device() returned nullptr if the lightgun had no name. Now it will create the device with a name using the lightgun's device index
* Change older m_display change to assert
This module can now be probed and disabled correctly if X11 is not being used. Removed the if statements that would be called every cycle (and fail silently) in favor of asserts, as MAME does not currently handle dynamic hardware configuration changes.
* Fixing semicolons in asserts that were ifs
* Removed sound CPU boot hack.
* Fixed sound CPU reset/halt behavior.
* Documented controller shift-register protocol and removed inaccurate direct port hookups.
* Removed P3/P4 ports which don't exist on real hardware.
* Added save state registration.
- moved netlists out of driver code into audio/ or machine/ as
nl_xxx.cpp files.
- identified and documented extended validation
- updated arcade, mess and nl targets
* 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
