c7462ce712 kernel/process: Make Process a WaitObject
Process instances can be waited upon for state changes. This is also
utilized by svcResetSignal, which will be modified in an upcoming
change. This simply puts all of the WaitObject related machinery in
place.

a3aa7aaf0b kernel/readable_event: Add member function for enforcing a strict reset contract
svcResetSignal relies on the event instance to have already been
signaled before attempting to reset it. If this isn't the case, then an
error code has to be returned.

a543c35962 kernel/svc: Implement svcSignalEvent()
This function simply does a handle table lookup for a writable event
instance identified by the given handle value. If a writable event
cannot be found for the given handle, then an invalid handle error is
returned. If a writable event is found, then it simply signals the
event, as one would expect.

2a1f59b301 kernel/svc: Implement svcCreateEvent()
svcCreateEvent operates by creating both a readable and writable event
and then attempts to add both to the current process' handle table.

If adding either of the events to the handle table fails, then the
relevant error from the handle table is returned.

If adding the readable event after the writable event to the table
fails, then the writable event is removed from the handle table and the
relevant error from the handle table is returned.

Note that since we do not currently test resource limits, we don't check
the resource limit table yet.

5eb057f422 kernel/object: Amend handle types to distinguish between readable and writable events
Two kernel object should absolutely never have the same handle ID type.
This can cause incorrect behavior when it comes to retrieving object
types from the handle table. In this case it allows converting a
WritableEvent into a ReadableEvent and vice-versa, which is undefined
behavior, since the object types are not the same.

This also corrects ClearEvent() to check both kernel types like the
kernel itself does.

7fe27de26e svc: Use the current process' handle table for retrieving the process instance to act upon
The kernel uses the handle table of the current process to retrieve the
process that should be used to retrieve certain information. To someone
not familiar with the kernel, this might raise the question of "Ok,
sounds nice, but doesn't this make it impossible to retrieve information
about the current process?".

No, it doesn't, because HandleTable instances in the kernel have the
notion of a "pseudo-handle", where certain values allow the kernel to
lookup objects outside of a given handle table. Currently, there's only
a pseudo-handle for the current process (0xFFFF8001) and a pseudo-handle
for the current thread (0xFFFF8000), so to retrieve the current process,
one would just pass 0xFFFF8001 into svcGetInfo.

The lookup itself in the handle table would be something like:

template <typename T>
T* Lookup(Handle handle) {
    if (handle == PSEUDO_HANDLE_CURRENT_PROCESS) {
        return CurrentProcess();
    }

    if (handle == PSUEDO_HANDLE_CURRENT_THREAD) {
        return CurrentThread();
    }

    return static_cast<T*>(&objects[handle]);
}

which, as is shown, allows accessing the current process or current
thread, even if those two objects aren't actually within the HandleTable
instance.

6712e7402c svc: Reorganize svcGetInfo, handle more error cases for existing implemented info categories
Our implementation of svcGetInfo was slightly incorrect in that we
weren't doing proper error checking everywhere. Instead, reorganize it
to be similar to how the kernel seems to do it.

db4523f1ec filesystem: De-globalize registered_cache_union
We can just return a new instance of this when it's requested. This only
ever holds pointers to the existing registed caches, so it's not a large
object. Plus, this also gets rid of the need to keep around a separate
member function just to properly clear out the union.

Gets rid of one of five globals in the filesystem code.

This is the same behavior-wise as DeleteDirectoryRecursively, with the
only difference being that it doesn't delete the top level directory in

  - some_dir/

  - OtherFile.txt

The end result is just:
