core: provide thread exec times via TRACE service
...
This patch enable clients of core's TRACE service to obtain the
execution times of trace subjects (i.e., threads). The execution time is
delivered as part of the 'Subject_info' structure.
Right now, the feature is available solely on NOVA. On all other base
platforms, the returned execution times are 0.

...
This patch installs the parent endpoint selector and the PD's CNode into
a PD at its creation time. Furthermore, it initializes the IPC buffer
for the main thread of the new component.

sel4: use core_printf for non-core components
...
This allows us to see debug messages printed at the eary initialization
of init (before init is able to obtain the regular LOG session). This
will be reverted as soon as the initialziation of the non-core base
environment works.

sel4: don't use base-common.mk in test roottask
...
To build core and other Genode components, we will need to extend the
base-common.mk library with additions that conflict with the
minimalistic root-task environment of test/sel4. To preserve the
minimalistic root task, we need to decouple it from the base-common
library.
