c740608242 docment the new sound drivers in LINT and add the necessary files to 
files.i386.

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.

acb902182f Fix the broken VT_WAITACTIVE ioctl for the case where the third arg 
was 0.

PR:		4164
Submitted by:	Joe Traister <traister@mojozone.org>

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.)

755b925e24 Addf flags 0x10 to the sio0 line, so it is available as a potential 
console.  This features backwards-compatibility to the era when sio(4)
was always available for a console.

27262cac33 Add __getcwd() syscall, and have getcwd() take a shot at it. 
If your kernel doesn't support __getcwd() or if __getcwd() cannot
deliver because of cache expiry, it does the canonical thing.

7822f1c624 Add a __getcwd() syscall. This is intentionally undocumented, but all 
it does is to try to figure the pwd out from the vfs namecache, and
return a reversed string to it.  libc:getcwd() is responsible for
flipping it back.

535db1806c Call poll(2) from within the resolver but adapt to older kernels without it 
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.

387dcb61ff When calling strip, temporarily close the file, call strip and then 
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.

c4ea5f72e6 SYSV has both <poll.h> and <sys/poll.h>. (poll.h merely #includes 
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.
