jonathan a44b6c74de Add emulation of ultrix mount(2). Sufficient to NFS-mount filesystems 
using a NetBSD kernel in an ultrix root filesystem.

Move wait emulation to the old (v7) wait syscall number, as that's
what the  Ultrix ufs_mount binary uses.

jonathan 6a363a1101 Add emulation of Ultrix select: before calling native sys_select(), 
limit the number of FDs to select on to the maximum supported by NetBSD --
which is as many FDs as the emul_ultrix process can have open, anyway.

Add emulation of Ultrix getmnt(2) in ultrix_fs.c

Add partial emulation of Ultrix tty ioctl()s in ultrix_ioctl.c, derived
from compat/sunos/sunos_ioctl.c.  Ultrix libc's ``isatty()'' now works
in compat_emul processes.
