25d71454d1 kernel/svc: Log svcBreak parameters 
Given if we hit here all is lost, we should probably be logging the
break reason code and associated information to distinguish between the
causes.

3476f5b4d3 kernel/object: Tighten object against data races 
Despite being covered by a global mutex, we should still ensure that the
class handles its reference counts properly. This avoids potential
shenanigans when it comes to data races.

Given this is the root object that drives quite a bit of the kernel
object hierarchy, ensuring we always have the correct behavior (and no
races) is a good thing.

Fixed a bunch of race conditions when running in multicore mode.

a9877c8f65 Kernel/SVC: Don't reschedule the current core when creating a new thread. 
The current core may have nothing to do with the core where the new thread was scheduled to run. In case it's the same core, then the following PrepareReshedule call will take care of that.

84b542c386 Kernel/Threads: Lock the HLE mutex when executing the wakeup callback. 
Another thread might be in the middle of a reschedule, thus altering the state of the schedulers.

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.

5224cc49c4 Kernel/Mutex: Don't duplicate threads in the mutex waiter list. 
Exit from AddMutexWaiter early if the thread is already waiting for a mutex owned by the owner thread.

This accounts for the possibility of a thread that is waiting on a condition variable being awakened twice in a row.

Also added more validation asserts.

This should fix one of the random crashes in Breath Of The Wild.

e850ff63bc scheduler: Make HaveReadyThreads() a const member function 
This function doesn't modify instance state, so the const qualifier can

da2f00ab7d client_port: Make all data members private 
These members don't need to be entirely exposed, we can instead expose
an API to operate on them without directly needing to mutate them

We can also guard against overflow/API misuse this way as well, given
active_sessions is an unsigned value.

2feb1a8ba6 kernel/event: Make data members private 
Instead we can simply provide accessors to the required data instead of
giving external read/write access to the variables directly.

7a77d0a71e address_arbiter: Return by value from GetThreadsWaitingOnAddress()

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).

Lioncash
2beda7c2b3 kernel/process: Use accessors instead of class members for referencing segment array 
Using member variables for referencing the segments array increases the
size of the class in memory for little benefit. The same behavior can be
achieved through the use of accessors that just return the relevant
segment.
