This patch attempts to clean up kvmctl so that it can be more easily made to

For dispatch, it's using a simple array as suggested by Avi.
For x86, we'll have two tables, a pio_table and an mmio_table. For PPC we can

The memory size is currently hardcoded into the linker script (end_of_memory).
This prevents the memory size from being specified dynamically in kvmctl.

tests.
