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.

5169de72c4 base: set default cpu affinity 
Set cpu_session default affinity space already during
construction of the thread, so that main thread is placed in the cpu affinity
space as defined by the parent. Otherwise the main thread is placed potentially
outside the affinity space, typically on the first/boot CPU.

93f06dd11a nova: set invalid affinity space in thread constructor 
Otherwise affinity space is set to 1x1 and in cpu_session_component.cc the cpu
session local affinity space defined by parent is not taken because
"Location::valid()" returns true.

02c16e7106 hw: split resume_local_thread from resume_thread 
Kernel::resume_thread was restricted to core when the targeted thread was in
another domain. Now there are two kernel calls, resume_local_thread and
resume_thread, where the former is never restricted and is provided via
public kernel/interface.h and the latter is always restricted to core and
is provided via core-local kernel/core_interface.h.

fba4f54571 hw: split pause_current_thread from pause_thread 
Kernel::pause_current_thread can be implemented much simpler and is not
restricted to core threads, in contrast to Kernel::pause_thread which
also benefits from the split and can be moved to core_interface.h.
