kernel: add functions for safely (un)locking pairs of objects
...
when locking a pair of objects, the object with the lesser memory address
is always locked first. the pair is unlocked in the opposite order.

vm: region: improve locking rules and semantics; implement region killing
...
the rules around acquiring locks have been strictly defined and
implemented, and general lock usage has been improved, to fix and
prevent several different issues.
a vm-region is now destroyed in two separate steps:
1. it is "killed": all mappings are unmapped and deleted, the
region is removed from its parent, and the region and all of
its sub-regions are marked as "dead", preventing any
further actions from being performed with the region.
2. it is "destroyed": the vm-region object is de-allocated when
the last reference/handle is closed. the references that this
region holds to any sub-regions are also released, meaning
these regions may also be de-allocated too.

include/mango within libmango.

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.
