that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).
There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.
Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

attempting to export the non-root of a filesystem with -alldirs. This
pilot error seems to be very common, and the "could not remount" error
message doesn't give much hints about the real reason. See the old PR
below for an example.
While i was at it, make it possible to entirely omit the often
annoying error message in that case by specifying the "quiet" exports
flag. This allows to specify something like
/cdrom -alldirs,ro,quiet <where to export to>
which will silently fail if nothing is mounted under /cdrom, but do
the rigth thing as soon as you mount something.
While doing this, i've put the embedded example in the exports(5) man
page into a subsection of its own as it ought to be.
Thanks for Paul Southworth for reminding me about this problem.

/etc/exports. Oversized lines were unlikely due to the large 10k
limit, but any found would cause mountd to exit with an error. Also
fix one or two compiler warnings.
It does not help modern compilers, and some may take some hit from it.
(I also found several functions that listed *every* of its 10 local vars with
"register" -- just how many free registers do people think machines have?)
spares (the size of the field was changed from u_short to u_int to
reflect what it really ends up being). Accordingly, change users of
xucred to set and check this field as appropriate. In the kernel,
this is being done inside the new cru2x() routine which takes a
`struct ucred' and fills out a `struct xucred' according to the
former. This also has the pleasant sideaffect of removing some
duplicate code.
