Fix an awful bug inside our COMPAT_43TTY code.
When I migrated tty_compat.c to MPSAFE TTY, I just hooked it up to the
build and fixed it until it compiled and somewhat worked. It turns out
this was not the smartest thing, because the old TTY layer also had a
field called t_flags, which contained a set of sgtty flags.
This means our current COMPAT_43TTY code overwrites the TTY flags,
causing all strange problems to occur. Fix this code to use a new struct
member called t_compatflags. This commit may cause kern/127054 to be
fixed, but this still has to be tested/confirmed by the originator. It
has to be fixed anyway.
