c5986c7bf7 kernel/server_session: Add IsSession() member function
Allows querying the inverse of IsDomain() to make things more readable.
This will likely also be usable in the event of implementing
ConvertDomainToSession().

9f6aa5cda8 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.

3485963fec 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.

a063b51094 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.

5fe52770ea 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.

cbf854666d 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.

8f493f43e7 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.

6082427cbd scheduler: Make HaveReadyThreads() a const member function
This function doesn't modify instance state, so the const qualifier can

5fcac98ec8 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.

11eadbccc9 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.

6f3a3ed8c5 kernel/thread: Fix potential crashes introduced in 3bcf090d37
This amends cases where crashes can occur that were missed due to the

don't exist).

73f162a5b0 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.

fa173d1874 kernel/thread: Make GetFreeThreadLocalSlot()'s loop indices size_t
