fix the return value of LdrLoadImage, make use of __declspec(dllexport), speed up blitting, add dummy TEB, redesign the syscall interface, fix stack alignent so movaps doesn't crash, implement a shitload of win32, implement a simple shell, add bink as video.exe 😎, minor kmain.c cleanup, HAL now supports power-off events, implemented \b in hal_screen.c, fix many deadlocks, add wait for exit event for processes, completely new error codes, small readme changes.
