The commit switches the kernel branch to r5 and updates the syscall bindings in base-nova accordingly. Beside some cleanups, r5 extents the ec_ctrl syscall to support following features: * An EC may yield its current timeslice. The timeslice gets enqueued at the end of the run queue without refreshing the left budget of the quantum. * An EC helps with the current SC another EC. Used in Genode to implement helping over a user-level lock to avoid live-lock situation. (Think of a limited priority-inheritance mechanism.) * An EC requests a new scheduler decision. Used in Genode to transfer back the potentially helping SC to the helper EC. Issue #986
