mm: move internal core VMA manipulation functions to own file
This patch introduces vma.c and moves internal core VMA manipulation
functions to this file from mmap.c.
This allows us to isolate VMA functionality in a single place such that we
can create userspace testing code that invokes this functionality in an
environment where we can implement simple unit tests of core
functionality.
This patch ensures that core VMA functionality is explicitly marked as
such by its presence in mm/vma.h.
It also places the header includes required by vma.c in vma_internal.h,
which is simply imported by vma.c. This makes the VMA functionality
testable, as userland testing code can simply stub out functionality as
required.
