* Start refactoring kernel a bit and import some changes from kernel decoupling PR * kernel: Put output always at the start in Syscall functions * kernel: Rewrite GetThreadContext3 to use a structure and to be accurate * kernel: make KernelTransfer use generic types and simplify * Fix some warning and do not use getters on MemoryInfo * Address gdkchan's comment * GetThreadContext3: use correct pause flag
