The only files which should be including vma.h are the implementation files for the core VMA logic - vma.c, vma_init.c, and vma_exec.c. This is in order to allow for userland testing of core VMA logic. In this cases, vma_internal.h and vma.h are included, providing both the dependencies upon which the core VMA logic requires and its declarations. Userland testable VMA logic is achieved by having separate vma_internal.h implementations for userland and kernel. Callers other than the core VMA implementation should include internal.h instead. This header does not need to include vma_internal.h as it only contains the vma.h declarations, for which the includes already present suffice. Update code to reflect this, update comments to reflect the fact there are 3 VMA implementation files and document things more clearly. While we're here, slightly improve the language of the comment describing vma_exec.c. No functional change intended.
