See vfs.git#work.tty-ioctl. Completely untested, should seriously
clean the things up wrt compat. Remaining problems (aside of the bugs
introduced in it, of course):
* TIOCSERGSTRUCT must die; it's present only in amiserial and it's
_vile_; look at what it copies out and weep.
See vfs.git#work.tty-ioctl. Completely untested, should seriously
