Fix mmap copying
Instead of attempting to map large files into memory at once, we map
chunks of at most `PHP_STREAM_MMAP_MAX` bytes, and repeat that until we
hit the point where `php_stream_seek()` fails (see bug 54902), and copy
the rest of the file by reading and writing small chunks.
We also fix the mapping behavior for zero bytes on Windows, which did
not error (as with `mmap()`), but would have mapped the remaining file.
