0135b328ed Kernel/Thread: Always use the threadsafe option when scheduling wakeups.
WakeAfterDelay might be called from any host thread, so err on the side of caution and use the thread-safe CoreTiming::ScheduleEventThreadsafe.

Note that CoreTiming is still far from thread-safe, there may be more things we have to work on for it to be up to par with what we want.

e93fa7f2cc kernel/thread: Fix potential crashes introduced in 26de4bb521
This amends cases where crashes can occur that were missed due to the
odd way the previous code was set up (using 3DS memory regions that
don't exist).

6058c84b79 kernel/thread: Make GetFreeThreadLocalSlot()'s loop indices size_t
Avoids using a u32 to compare against a range of size_t, which can be a
source of warnings. While we're at it, compress a std::tie into a
structured binding.

fac0e42b2f kernel/thread: Make GetFreeThreadLocalSlot() reference parameter a const reference
This function only reads the data being referenced, it doesn't modify
it, so we can turn the reference into a const reference.

9a50a4f2cc kernel/thread: Make GetFreeThreadLocalSlot() internally linked
This function isn't used outside of this translation unit, so we can

bf45092c61 kernel: Move object class to its own source files
General moving to keep kernel object types separate from the direct
kernel code. Also essentially a preliminary cleanup before eliminating
global kernel state in the kernel code.

a2304fad16 kernel: Remove unnecessary includes
Removes unnecessary direct dependencies in some headers and also gets
rid of indirect dependencies that were being relied on to be included.

dbfe82773d thread: Convert ThreadStatus into an enum class
Makes the thread status strongly typed, so implicit conversions can't
happen. It also makes it easier to catch mistakes at compile time.

3a4841e403 core: Don't construct instance of Core::System, just to access its live instance
This would result in a lot of allocations and related object
construction, just to toss it all away immediately after the call.

These are definitely not intentional, and it was intended that all of
these should have been accessing the static function GetInstance()
through the name itself, not constructed instances.

9cd87a6352 Kernel/Threads: A thread waking up by timeout from a WaitProcessWideKey may already have an assigned lock owner.
This situation may happen like so:
Thread 1 with low priority calls WaitProcessWideKey with timeout.
Thread 2 with high priority calls WaitProcessWideKey without timeout.
Thread 3 calls SignalProcessWideKey
- Thread 2 acquires the lock and awakens.
- Thread 1 can't acquire the lock and is put to sleep with the lock owner being Thread 2.
Thread 1's timeout expires, with the lock owner still being set to Thread 2.

46572d027d Kernel: Implemented mutex priority inheritance.
Verified with a hwtest and implemented based on reverse engineering.

Thread A's priority will get bumped to the highest priority among all the threads that are waiting for a mutex that A holds.
Once A releases the mutex and ownership is transferred to B, A's priority will return to normal and B's priority will be bumped.

e81a2080eb Kernel: Corrected the implementation of svcArbitrateLock and svcArbitrateUnlock.
Switch mutexes are no longer kernel objects, they are managed in userland and only use the kernel to handle the contention case.
Mutex addresses store a special flag value (0x40000000) to notify the guest code that there are still some threads waiting for the mutex to be released. This flag is updated when a thread calls ArbitrateUnlock.

TODO:
* Fix svcWaitProcessWideKey
* Fix svcSignalProcessWideKey
* Remove the Mutex class.

94ee8fc97b Kernel/IPC: Add a small delay after each SyncRequest to prevent thread starvation.
Ported from citra PR #3091

The delay specified here is from a Nintendo 3DS, and should be measured in a Nintendo Switch.

This change is enough to prevent Puyo Puyo Tetris's main thread starvation.
