base: resolve dead lock in weak pointer templates
...
This commit eliminates the mutual interlaced taking of destruction lock,
list lock and weak pointer locks that could lead to a dead-lock situation
when a lock pointer was tried to construct while a weak object is in
destruction progress.
Now, all weak pointers are invalidated and dequeued at the very
beginning of the weak object's destruction. Moreover, before a weak pointer
gets invalidated during destruction of a weak object, it gets dequeued, and
the list lock is freed again to avoid the former dead-lock.

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.

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.
