(handler_pty_slave::open_setup): Reflect argument change in pinfo::set_ctty. (handler_pty_master::open_setup): Define new function. (fhandler_pty_master::cleanup): Clear handles as a flag that the destructor does not have to do "close" operations. (fhandler_pty_master::close): Ditto. (fhandler_pty_master::~fhandler_pty_master): Define new method. (fhandler_pty_master::ioctl): Reflect name/arg change for ioctl_termios. (fhandler_pty_master::setup): Allocate tty here. Rely on handles being returned from allocated test rather than opening them here. Avoid setting _need_nl here since it is already zeroed in the constructor. Set up device information with DEV_TTYM_MAJOR. * path.h (path_conv &operator =): Take a const argument. (path_conv::dup): Ditto. (pathconv_arg::PC_OPEN): New enum. (pathconv_arg::PC_CTTY): Ditto.

Avoid keeping the lock since the allocation of the tty should be sufficient to prevent multiple access. (tty::not_allocated): Clarify comment. Rename. Return handles when an unused tty is found. Simply test for existing tty. (tty::exists): Rewrite to use `not_allocated'. * tty.h (NTTYS): Reset down to actual number supported by devices.in. (tty::not_allocated): Declare new function. (tty_list::allocate): Pass out read/write tty handles. Zero them when not found. * fhandler_proc.cc: Reflect name change from FH_PTYM -> FH_PTMX. * pinfo.h (pinfo::set_ctty): Reduce/reorder arguments passed in. * pinfo.cc (pinfo::set_ctty): Ditto. Just use tc() built into the passed-in fhandler_termios pointer. Return true if ctty is assigned. * syscalls.cc (open): Call build_fh_pc with PC_OPEN flag. Set PC_CTTY if appropriate. (stat_worker): Remove is_dev_tty () stuff.

(fhandler_dev_floppy::open): Rearrange comment. (fhandler_dev_floppy::dup): New method. (fhandler_dev_floppy::get_current_position): New inline method. Use instead of former current_position were appropriate. (fhandler_dev_floppy::raw_read): Move here. Drop EOF handling. (fhandler_dev_floppy::raw_write): Move here. Drop EOF handling. (fhandler_dev_floppy::lseek): Remove useless conditions. Convert sector_aligned_offset to LARGE_INTEGER to improve SetFilePointer call.
