Add a simple mmap wrapper for cross-platform mmap usage Win32 has a variant of mmap that is harder to use than POSIX, but to run natively and efficiently on Win32 we need some form of it. gitfo_map_ro() provides a basic mmap function for use in locations where we need read-only random data access to large ranges of a file, such as a pack-*.idx.
