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.

vm: add vm-object to represent non-contiguous physical memory allocations
...
vm-object can be used to demand-allocate non-contiguous physical memory, and
will provide an api for userspace programs to do the same. unless a vm-object
is created in-place (i.e. to represent a specific area of physical memory),
its memory pages are only allocated when the object is mapped AND someone
attempts to access the memory.
