01e9ccbd9c Back out just a portion of Alfred's last commit. Remove the MBUF_CHECK
(WITNESS) for code paths that always call uma_zalloc_arg() shortly
after where the check was, because uma_zalloc_arg() already does
a similar check.

No objections from Alfred.  Thanks Alfred.

55db762b76 Extend versrcreach by checking against the rt_flags for RTF_REJECT and
RTF_BLACKHOLE as well.

To quote the submitter:

 The uRPF loose-check implementation by the industry vendors, at least on Cisco
 and possibly Juniper, will fail the check if the route of the source address
 is pointed to Null0 (on Juniper, discard or reject route). What this means is,
 even if uRPF Loose-check finds the route, if the route is pointed to blackhole,
 uRPF loose-check must fail. This allows people to utilize uRPF loose-check mode
 as a pseudo-packet-firewall without using any manual filtering configuration --
 one can simply inject a IGP or BGP prefix with next-hop set to a static route
 that directs to null/discard facility. This results in uRPF Loose-check failing
 on all packets with source addresses that are within the range of the nullroute.

9906740e39 Add support for ignoring locking failures. This is only enabled when
you've specified a directory.  It is intended to be used in building
custom releases over NFS where locking may be unreliable at best and
there is no contention that the locking is designed to arbitrate.
Other uses of this flag are discouraged.  Document same in usage and
man page (including the warning about unwise).

24412bd1af Two style related changes:
(1) use strlcpy instead of strncpy since the use here of the latter
    was incorrect.
(2) Move 'N' case into proper sorted order (sorted the same way that
    ls sorts its args).

46e38ce826 Don't sync the file system on panic by default. This seems to basically
work very infrequently, and often results in a compound panic which
confuses debugging; locking/SMP have made the layering violation (and
risks) of this more obvious over time.

fd32d93b97 Unify db_stack_trace_cmd(). All it did was look up the thread given
the thread ID and call db_trace_thread().
Since arm has all the logic in db_stack_trace_cmd(), rename the
new DB_COMMAND function to db_stack_trace to avoid conflicts on
arm.
While here, have db_stack_trace parse its own arguments so that
we can use a more natural radix for IDs. If the ID is not a thread
ID, or more precisely when no thread exists with the ID, try if
there's a process with that ID and return the first thread in it.
This makes it easier to print stack traces from the ps output.

3f25cbddc2 Move the initialization and teardown of pmaps to the vmspace zone's
init and fini handlers.  Our vm system removes all userland mappings at
exit prior to calling pmap_release.  It just so happens that we might
as well reuse the pmap for the next process since the userland slate
has already been wiped clean.

However.  There is a functional benefit to this as well.  For platforms
that share userland and kernel context in the same pmap, it means that
the kernel portion of a pmap remains valid after the vmspace has been
freed (process exit) and while it is in uma's cache.  This is significant
for i386 SMP systems with kernel context borrowing because it avoids
a LOT of IPIs from the pmap_lazyfix() cleanup in the usual case.

239c9e601a Currently if a mount point is not accessible by the calling user,
invalid information will be printed if the -t flag is specified.

$ df -t ufs
Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/ad0s1a    495726   139944   316124    31%    /
/dev/ad0s1e    253678     6438   226946     3%    /tmp
/dev/ad0s1f  56206340 13594248 38115586    26%    /usr
/dev/ad0s1d    694126    19812   618784     3%    /var
/dev/ad0s1d    694126    19812   618784     3%    /var
$

Note that the mount point which is not accessible shows
up as the previous file system that was printed. The reason
for this is that df -t will call statfs(2) on the pathname
supplied by getfsstat(2).

This is done to refresh the file system statistics in the
event that a previous file system had a long delay in
providing its stats.

This change affects the df utility in the following ways:
o Teach df has to deal with statfs(2) failing. If statfs(2)
  fails, fall back on the possibly stale stats provided by
  the initial call to getfsstat(2).
o Print a warning that the fs stats could possibly be stale
o Modify the man page and document this new behavior
  as a bug.
