* OpenBSD: BSS is immutable so mark it as mutable so that mprotect RWX works
see: mimmutable(1)

* OpenBSD does not have mcontext_t
<signal.h> provides `typedef struct sigcontext ucontext_t;'.
take register names from <machine/signal.h>, which provides struct
sigcontext.

* OpenBSD uses major.minor for shared libs, so properly dlopen libGL.so
* OpenBSD remove redefinition of swap16
* OpenBSD: SDL2 controller detection
Use sdl_open_joystick() to open controllers on startup instead of
SDL_JOYDEVICEADDED event, which never gets detected.
* OpenBSD does not have mcontext_t but linux does
* cmake: use c++17
* Use std::size
* Use std::make_unique
* Use std::clamp
* Use structured binding
* Use [[fallthrough]]
* Use enable_if_t/is_enum_v/is_integral_v/is_same_v
* Use if constexpr
* Use try_emplace
* Use auto for iterators
* Use inline variables
actual aica arm clock seems to be 22.5792 MHz, which means 512 cycles
per sample at 44.1 KHz (from 256)
fixes vf4 audio hiccup in character selection screen
delegate to previous signal handler, proper abort for win32
arm32: use builtin gcc __clear_cache
dyna/driver.cpp: no need for a code buffer in win32, cleanup
* Add audio arm64 cpp into Xcode project
* Build universal binary for SDL2 also
* Add vixl aarch64 dependency + build arm64 in cmake
* hardcode pagesize for M1 CPU
* Use `MAP_JIT` and toggle between RX and RW
* add pthread.h for cmake
* Disable audio dynarec temporary
* Enable aica arm dynarec
* Supports `br` with condition
* Dynamic linker flag for libSDL2.a since Homebrew path is different on arm (for xcodeproj)
* Fallback path for Intel
* de-dup for arm64, allow cross compilation on both Intel and Apple Silicon Mac
* Rename WriteProtect() to JITWriteProtect(), Move JITWriteProtect from arm7_rec to arm7_rec_arm64
* Remove CodeCache memset
* Remove keyboard_device.cpp from xcodeproj
* Use hard tab
* Update libchdr to support compiling on M1 (thanks @scribam)
