Merge support for capabilities from lp:~jakub/helenos/caps

This commit introduces capabilities as task-local names for references to kernel
objects. Kernel objects are reference-counted wrappers for a select group of
objects allocated in and by the kernel that can be made accessible to userspace
in a controlled way via integer handles.

So far, a kernel object encapsulates either an irq_t or a phone_t.

Support for the former lead to the removal of kernel-assigned devnos and
unsecure deregistration of IRQs in which a random task was able to unregister
some other task's IRQ.
