* IPC refactor part 2: Use ReplyAndReceive on HLE services and remove special handling from kernel * Fix for applet transfer memory + some nits * Keep handles if possible to avoid server handle table exhaustion * Fix IPC ZeroFill bug * am: Correctly implement CreateManagedDisplayLayer and implement CreateManagedDisplaySeparableLayer CreateManagedDisplaySeparableLayer is requires since 10.x+ when appletResourceUserId != 0 * Make it exit properly * Make ServiceNotImplementedException show the full message again * Allow yielding execution to avoid starving other threads * Only wait if active * Merge IVirtualMemoryManager and IAddressSpaceManager * Fix Ro loading data from the wrong process Co-authored-by: Thog <me@thog.eu>
