Mutex: Changed behavior to always release mutex for all threads.
SVC: SleepThread should yield to the next ready thread.

arm_dyncom_interpreter: Get rid of unused var warnings

MSVC fast.
GLFW: Add an error callback before calling glfwInit()

It will print a message to know what happened in case something went wrong in a GLFW call.

Also replace every printf() in the glfw emu-window by ERROR_LOG().
