Alexander Boettcher ecaf09a41b nova: extent ec_ctrl in kernel and base-nova
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.
