This isn't used anywhere and not really a generic utility, so we can get
rid of it.
This also lets us remove MathUtil.cpp, since this was the only thing
within that file.
Fixes us forgetting to add its include directories, which could result in linking to a dylib from MacPorts while using the system's header, and failing to link because they use different function names
Added AchievementSettings in Config with RA_INTEGRATION_ENABLED, RA_USERNAME, and RA_API_TOKEN. Includes code to load and store from Achievements.ini file in config folder.
This fixes a crash when recording fifologs, as the mutex is acquired when BPWritten calls AfterFrameEvent::Trigger, but then acquired again when FifoRecorder::EndFrame calls m_end_of_frame_event.reset(). std::mutex does not allow calling lock() if the thread already owns the mutex, while std::recursive_mutex does allow this.
This is a regression from #11522 (which introduced the HookableEvent system).
This second stack leads to JNI problems on Android, because ART fetches
the address and size of the original stack using pthread functions
(see GetThreadStack in art/runtime/thread.cc), and (presumably) treats
stack addresses outside of the original stack as invalid. (What I don't
understand is why some JNI operations on the CPU thread work fine
despite this but others don't.)
Instead of creating a second stack, let's borrow the approach ART uses:
Use pthread functions to find out the stack's address and size, then
install guard pages at an appropriate location. This lets us get rid
of a workaround we had in the MsgAlert function.
Because we're no longer choosing the stack size ourselves, I've made some
tweaks to where the put the guard pages. Previously we had a stack of
2 MiB and a safe zone of 512 KiB. We now accept stacks as small as 512 KiB
(used on macOS) and use a safe zone of 256 KiB. I feel like this should
be fine, but haven't done much testing beyond "it seems to work".
By the way, on Windows it was already the case that we didn't create
a second stack... But there was a bug in the implementation!
The code for protecting the stack has to run on the CPU thread, since
it's the CPU thread's stack we want to protect, but it was actually
running on EmuThread. This commit fixes that, since now this bug
matters on other operating systems too.
