Now we have eliminated all uses of vm_area_desc->vm_flags, eliminate this field, and have mmap_prepare users utilise the vma_flags_t vm_area_desc->vma_flags field only. As part of this change we alter is_shared_maywrite() to accept a vma_flags_t parameter, and introduce is_shared_maywrite_vm_flags() for use with legacy vm_flags_t flags. We also update struct mmap_state to add a union between vma_flags and vm_flags temporarily until the mmap logic is also converted to using vma_flags_t. Also update the VMA userland tests to reflect this change.
