We aren't sure if this new code and the old sound code will co-exist in a
kernel, so the device pcm0 line is left commented out in LINT.

While i was at it, also fixed a broken return value for the VT_RELDISP
ioctl, iff the third arg was legally VT_TRUE, but the destination
screen was in process mode so the actual switch had to be deferred.
This was breaking the ability to directly toggle between two X servers
running on two VTs, since the server getting the bogus error return
was running wild, and competing with the other one for the hardware.
(Sigh, this was a very long-standing bug.)
if necessary. This removes the need to malloc large fd_set's for selecting
on high fd's (larger than FD_SETSIZE at libc compile time).
The syscall adaptive stuff only happens on the very first call. SIGSYS
is masked, and if the call to poll fails with ENOSYS, then we use select
for the life of the program. If poll does not fail with ENOSYS, then we
always use poll and skip the once-off signal masking gunk.
This may be overkill, but it saved my neck a few times while working on
multiple different sets of kernel sources, some with poll, some without.
reopen it after strip has finished. This makes it work when
/usr/bin/strip replaces the file rather than doing an in-place edit
(such as the binutils-2.8 strip, which is a variation of objcopy).
This is necessary if install(1) and strip(1) are going to cooperate
on an ELF system.
sys/poll.h). Just provide a link, it's close enough. :-) In an ideal
world the prototype for poll() would be in <poll.h> but some code seems
to expect it in <sys/poll.h>, so we can't win there.
adapted from NetBSD.. However, there are some differences in the tty
system that are big enough to cause their code to not fit comfortably.

detail is passed back and forwards). This mostly came from NetBSD, except
that our interfaces have changed a lot and this funciton is in a different
part of the kernel.
