vm: replace vm-region with address-space
...
address-space is a non-recursive data structure, which contains a flat list of vm_areas representing
mapped vm-objects.
userspace programs can no longer create sub-address-spaces. instead, they can reserve portions of
the address space, and use that reserved space to create mappings.

vm: add vm-region to manage userspace virtual memory address spaces
...
vm-region supports creating nested regions of virtual memory, each with their
own memory protection restrictions.
vm-objects can be mapped into a vm-region, making the underlying memory
accessible. all mappings are lazy: page tables are not updated until the
mapped memory is accessed.
