vm: implement private and shared address space mappings
...
whether a mapping is private or shared determines how the mapping is handled
when a task is duplicated.

kernel: msg: async messages no longer hold a pointer to the thread/port that sent them
...
this prevents a race condition where an event is sent as a port is being destroyed.
when the server gets around to handling the event, it now refers to a different port
that was created in the mean-time.

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.

handle: re-arrange handle space layout

the lowest 2 bits of handle values are no longer unused, and 0 is
now a valid handle value.
the first 64 handles are now reserved, and will not be automatically
allocated by the kernel. however, they are still valid handles, and
other handles can be moved to this area using an as-yet-unwritten
function. this is to allow support for standard POSIX file descriptors,
which require the values 0, 1, and 2.
