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.
This commit introduces a new memory model that supports true shared memory with separate permissions for remote and local processes, implements svcQueryMemory and completes svcGetInfo further, adds IPC support with the IpcRequest and IpcResponse classes.
