File::Locate::Iterator::FileMap -- shared mmaps for File::Locate::Iterator

This is an internal part of File::Locate::Iterator. A FileMap object holds a file mmapped by File::Map and will re-use it rather than mapping the same file a second time.

This module shouldn't exist, since File::Map is in a much better position to share read-only mmaps, and can do so across threads too. Almost every read-only mmap will want to share. Straightforward cases like an mmap of a whole file should definitely share.
