66d20a9429 Fix GroupMutex and Clock Rescaling
This commit mainly fixes GroupMutex and clock rescaling. In addition, clock rescaling is no longer performed if the CNTFRQ_EL0 of the host device is same as that of the Switch (19.2MHz) which is fairly common on higher end devices.

694c8ef4e2 Addition of Conditional Variables
This commit adds working conditional variables, in addition to the mutex and threading implementation. It directly depends on the memory optimization from the previous commit to be able to perform atomic operations on the mutex.

03b65bd90a Optimize Memory Implementation using Shared Memory
This commit further improves the memory implementation by using shared memory for all allocations so we won't have to depend on a kernel call for doing any host <-> guest memory transfers.

d02267c34f Add support for threads and mutexes
This commit adds support for threading and mutexes. However, there is also a basis of conditional variables but these don't work due to the lack of a shared memory model between the guest and host. So, conditional variables will be deferred to after the shared memory model is in place.

2aebf04b4b guest: Add memory barrier after saving context
Forces all registers to be saved before signalling to the kernel that we
are ready; without this the kernel may read incorrect context data
causing undefined behaviour.

00cdc1fd6f Refactor the memory implementation and add Regions
This commit does a major refactor of the memory implementation, it forms a memory map which is far cleaner than trying to access it through a handle table lookup. In addition, it creates a common interface for all memory kernel objects: KMemory from which all other kernel memory objects inherit. This allows doing resizing, permission change, etc without casting to the base memory type.

81dba3da4b KProcess: Use process_{read, write}_vm to access guest memory
This is much quicker than pread/write however we now need to abide by the
regions permissions, so fallback to pread/write if read/write vm fails.

65018aedbc Complete making the kernel thread-safe #2 + Fix Shared Memory Implementation
This commit makes the kernel completely thread-safe and fixes an issue that caused libNX games to not work due to an error with KSharedMemory. In addition, implement GroupMutex to allow the kernel threads to run in parallel but still allow them to not overlap with the JNI thread.

de6d8d8f48 Work on making the kernel thread-safe #1 + add asynchronous ROM scanning
This commit makes the kernel thread safe in some instances (but not fully) and showcases the significantly improved performance over the ptrace method used prior. In addition, scanning for ROMs is now done asynchronously.

970dde8c27 Move from ptrace to junction branching and make kernel multithreaded
This commit is a huge step in the direction of better performance, as we move from ptrace to junction branching and have kernel call overhead similar to that of a native kernel call! In addition, this sets the base for the kernel to go fully multi-threaded. However, the kernel is currently not thread-safe and therefore this commit currently causes a crash.
