Replace is_fs_device with is_fs_special throughout.unlabeled-1.88.2

* Makefile.in (DLL_OFILES): Add fhandler_fifo.o.
* devices.h (fh_devices): Renumber some minor numbers to fit in 8 bits.
* dtable.cc (dtable::build_fhandler): Handle FH_FIFO.  Set errno to ENODEV if
device not found.
* dtable::find_fifo: Define new function.
* dtable.h (dtable::find_fifo): Declare new function.
* fhandler.cc (fhandler_base::device_access_denied): Fix O_RDONLY test.
(fhandler_base::write): Use output file handle for writing.
(fhandler_base::fstat): Use is_fs_special rather than is_fs_device.
* fhandler.h (fhandler_base::is_fs_special): Rename from is_fs_device.
(fhandler_pipe): Make private elements protected so that fhandler_fifo can use
them too.
(fhandler_pipe::create): New function derived from make_pipe.
(fhandler_fifo): Add more needed elements.
(fhandler_pty_master::slave): Add to track slave device.
(fhandler_pty_master::get_unit): Define.
* fhandler_tty.cc (fhandler_tty_master::init): Register slave device.
(fhandler_pty_master::open): Ditto.
(symlink_info::parse_device): Handle fifo specially.
* pinfo.cc (_pinfo::commune_recv): Initial fifo implementation.
(_pinfo::commune_send): Ditto.
* pinfo.h (picom): Add PICOM_FIFO.
* pipe.cc (fhandler_pipe::close): Close input handle here specifically.
(fhandler_pipe::create): Rename from make_pipe.  Create fhandlers rather than
fds.
(pipe): Use fhandler_pipe::create to create pipe.
(_pipe): Ditto.
* syscalls.cc (mknod): Accommodate fifos.
