  "read_size".
- Changed some int vars in map_ptr() needed to be int32 vars.
- All callers expect map_ptr() to return back the full "len" bytes,
  so we never shorten this value, even near EOF--the read will
  just get zero-padded, as needed.
- Die with an error if someone calls map_ptr() with a len < 0, or
  if read_size is computed as a value < 0.

- Added define for MAX_BLOCK_SIZE.
- Reorder the variables in the structure defs to sort by size.
- Some vars in map_struct needed to be int32 instead of int.

  be improved in the future because it blocks options such as
  --block-size=N, but without this rule the user could specify
  something like --files-from=FILE or --backup-dir=DIR and have
  it affect files outside the desired SUBDIR restriction.

- Strip "::ffff:" from the start of an IP from SSH_CONNECTION.
