Message:

This is the evil commit. In particular, it does:

• introduces more powerful pseudo code for userspace IRQ top-half handlers
• changes the internals of IRQ dispatching
• simplifies the kernel's i8042 driver
• adapts the uspace i8042 driver to make use of the new pseudocode
• breaks all other architectures except ia32
• breaks almost all existing drivers
• breaks switching between uspace and kernel drivers
