909ab8dcd0 hw: communicate page faults via signals
Enable routing of thread events to signal contexts via
Kernel::route_thread_event.

Replace Kernel::set_pager by Kernel::route_thread_event.

In base-hw a pager object is a signal context and a pager activation
is a signal receiver. If a thread wants to start communicating its page
faults via a pager object, the thread calls Kernel::route_thread_event with
its thread ID, event ID "FAULT", and the signal context ID of the pager object.
If a pager activation wants to start handling page faults of a pager object,
the pager activation assigns the corresponding signal context to its signal
receiver. If a pager activation wants to stop handling page faults of a pager
object, the pager activation dissolves the corresponding signal context from
its signal receiver. If a thread wants to start communicating its page faults
via a pager object, the thread calls Kernel::route_thread_event with its
thread ID, event ID "FAULT", and the invalid signal context ID.

Remove Kernel::resume_faulter.

Move all page fault related code from generic kernel sources to CPU
specific cpu_support.h and cpu_support.cc.

c56927b76e hw: differ ID allocators even with same size
Previously, if two ID allocators for different kernel objects had the
same size, the kernel-object framework managed both objects types
through the same allocator instance. This is caused by the use of
unsynchronized singletons in the accessor functions and can be avoided
by creating new types through inheritance instead of using typedefs.
Anyways, this fix is a little bit ugly and should replaced by avoiding
the use of unsynchronized singletons in the future.
