Steve Reinhardt 2e47aaabc0 Add hook to call map() on Process from python.
This enables configuration scripts to set up mappings
from process virtual addresses to specific physical
addresses in SE mode.  This feature is needed to
support modeling of user-accessible memories or
devices in SE mode, avoiding the complexities of FS
mode and the need to write a device driver.
