Better don't allow builtins for the kernel.
Added missing newline.
[eco32,mmix] Bugfix in vga update.
Fixed CPU-time accounting for the case where we don't switch.
Better validate the cursor in VESA.
Don't use LAPIC for bus-speed-detection if it's not available.
uimng: ensure that the screenMode is set for the active client.
Prevent that one can map the same region twice in one process.
Fixed race conditions in channel.
Fixed fd closing in uimng.

We could optimize that by e.g. using the property that we always
get the smallest free fd and thus do a dup() to see how many fds
we already have. But I think it isn't worth it.
Take care that the current client might have no screen.
Return errno if mmap failed, not -ENOMEM.
ts: show CPU a thread is currently running on.
Improved priority adjustment scheme.

Now we do that based on the blocking time instead of the CPU
time, which behaves much better if someone creates a large
amount of CPU intensive threads (previously, the system was
basically dead in this case). For details, see comments.
Additionally, processes receive the minimum priority of all their
threads and inherit this priority to created threads and child
processes (bad guys are likely to spawn more bad guys ;)).
[eco32,mmix] fixed warnings.
