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.

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.

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.

It's finally here, we're executing code completely natively. This is something that would completely break the project if it wasn't possible.
