* fhandler.cc (fhandler_base::open): When creating a file on a
filesystem supporting ACLs, create the file with WRITE_DAC access.
Explain why.
* fhandler_disk_file.cc (fhandler_disk_file::mkdir): Ditto for
directories.
* fhandler_socket.cc (fhandler_socket::bind): Ditto for sockets.
* path.cc (symlink_worker): Ditto for symlinks.
* security.cc (get_file_sd): Always call GetSecurityInfo for directories
on XP and Server 2003. Improve comment to explain why.
(set_file_attribute): Explicitely cast mode_t value to bool in call to
get_file_sd.
* wincap.h (wincaps::use_get_sec_info_on_dirs): New element.
* wincap.cc: Implement above element throughout.
