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.
