so that the new behaviour is now default.
Solves the "infinite loop in diversion" problem when more than one diversion
is active.
Man page changes follow.
The new code is in -stable as the NON default option.
printf() of "Out of mbuf clusters - adjust NMBCLUSTERS or increase
maxusers" so that the message is more informative and so that it will
appear in the kernel message buffer.
the alloc is not M_DONTWAIT, then panic with "Out of mbuf clusters".
Callers that specify M_WAIT can't deal with getting a NULL buffer, so this
is a more graceful failure than randomly page faulting in the socket code
or elsewhere.
miscconfigured case) if the port is the console. This fixes several
bugs:
- if all sioprobe()s failed, then the console driver followed null
pointers in cdevsw[].
- if the sioprobe() for the console failed but another sioprobe()
succeeded, then init hung early when the console couldn't be
opened.
- it was silly for the console to not be there after printing boot
messages on it.
Bugs introduced by this are hopefully no worse than old ones caused
by forcing the success of the `cn' level probe.
Only complain about an irq mismatch in the probe if the configured
irq doesn't become active, and then print the bitmap of irqs that
became active (including clock irqs) instead of just the first
(not including clock irqs).

probe and intialisation. This will ultimately remove the grubby (but
functional) hack that copies a real-mode function into low memory
early in locore.s.
layer does not like the null shmid_ds buffer pointer. The emulation layer
returned an error without ever calling FreeBSD's shmctl, so the segments
were not being deleted when the reference count went to zero."

readrpc/writerpc, since they assume it's already been done. This could
break if the first read/write access to a nfs filesystem was an exec() or
mmap() instead of a read(), write() syscall. (or statfs()).
nfs_getpages() could return an errno (EOPNOTSUPP) instead of a VM_PAGER_*
return code. Some layout tweaks for the get/putpages code.
an (over?) conservative assumption about what the client can store in it's
buffer cache using a signed 32-bit 512-byte block number index. Otherwise
it's possible for some file access when maxfilesize = 0 (eg: /usr is nfs
mounted and doing an execve())

XXX It might make sense to do a preemptive nfs_fsinfo() call at mount time.
it just makes more work. We pass a copy of the uid/gid with the
credentials. (although, this may need to be revisited if a non AUTHUNIX
authentication method (such as NFSKERB) ever gets implemented).
