It's not ideal but (I think) better than it was before. The width is
limited to within 8..16.
and released. It should use `spcl' consistently in both cases,
otherwise shift/control/alt state may not be correctly set/reset.
(Even with this fix, you can still make syscons confused and fail to
change internal state if you really want to, by installing a really
arcane and artificial keymap.)

chown(). Previously, it wasn't marked for null chown()'s. We
permit null chown()s as a special case of "appropriate privilege"
- everyone has enough priviilege to not change ids (this is a better
argument than the one I gave for rev.1.13, that null changes aren't
really changes). However, POSIX.1 requires the update independently
of whether anything has changed.
Clear both the setuid and the setgid bits upon successful completion
of non-null chown()s by non-root. Previously, the setuid bit was
only changed for non-null changes of the uid, etc. POSIX.1 requires
clearing both unless the call was made by a process with "appropriate
privilege", in which case altering the bits is implementation-defined.
We define appropriate privilege as `process is root, or the change
is null', and the implementation-defined behaviour as not altering
the bits. There is no interpretation that permits clearing only
one of the bits.

but were missing prefixes so gas assembled them bogusly), and
rearranging a loop to test at the end.
better hack in ffs_vfsops.c. The hack here restricted the maximum file
size to 2^39 bytes (512GB). fs_bsize * 2^31 - 1 (16TB for the default
blocksize of 8K) would have been better. There is no good way to remove
this limit on old BSD4.4 file systems.

and SIGALRM to interrupt the system call, instead of restarting them.
Also try to get rid of some potential races Bruce didn't like; hopefully
they aren't a problem (potential or otherwise) now.
