Merged MAP and VIRTMEM/PHYSMEM capabilities into one.

Browse Source 
VIRTMEM and PHYSMEM are theoretically separate resources to be
protected than a MAP resource, which is meant to protect the syscall
privileges.

In practice MAP is always used together with a VIRTMEM and a PHYSMEM
resource, therefore reach VIRTMEM/PHYSMEM resource is now merged with
the MAP capability, combining the micro-permission bits.
