Commit b3d4c70dc6 added support for CLAIM_DELEG_CUR_FH to Open.
While doing this, I noticed that CLAIM_DELEG_PREV_FH support
could be added the same way. Although I am not aware of any extant
NFSv4.1/4.2 client that uses this claim type, it seems prudent to add
support for this variant of Open to the NFSv4.1/4.2 server.
This patch does not affect mounts from extant NFSv4.1/4.2 clients,
as far as I know.

kldxref(8) is the only tool that can dump FreeBSD kernel module
metadata, with the -d option. But the command line requirements for that
are inconvenient, since parser requires that argv[1] is a directory
containing whole set of modules to generate xref file.
For -d, allow argv[0] to be a regular file, now it is possible to do e.g.
$ kldxref -d /boot/kernel/ufs.ko
to see only ufs.ko metadata.

cxgbei stores state about a target transfer in the ctl_private[] array
of a ctl_io that is freed when a target transfer (represented by the
cdw) is freed. As such, freeing a ctl_io before a cdw that references
it can result in a use after free in cxgbei. Two of the four places
freed the cdw first, and the other two freed the ctl_io first. Fix
the latter two places to free the cdw first.

At this point the directory's vnode lock is held, so blocking while
waiting for free pages makes the system more susceptible to deadlock in
low memory conditions. This is particularly problematic on NUMA systems
as UMA currently implements a strict first-touch policy.
ufsdirhash_build() already uses M_NOWAIT for other allocations and
already handled failures for the block array allocation, so just convert
to M_NOWAIT.

The following config could crash pfctl:
altq on igb0 fairq bandwidth 1Gb queue { qLink }
queue qLink fairq(default)
That happens because when we're parsing the parent queue (on igb0) it
doesn't have a parent, and the check in eval_pfqueue_fairq() checks
pa->parent rather than parent.
This was changed in eval_pfqueue_hfsc() in
1d34c9dac8, but not for fairq.

Floating states get assigned to interface 'all' (V_pfi_all), so when we
try to flush all states for an interface states originally created
through this interface are not flushed. Only if-bound states can be
flushed in this way.
Given that we track the original interface we can check if the state's
interface is 'all', and if so compare to the orig_if instead.

The most difficult NFSv4 client recovery case happens when the
lease has expired on the server. For NFSv4.0, the client will
receive a NFSERR_EXPIRED reply from the server to indicate this
has happened.
For NFSv4.1/4.2, most RPCs have a Sequence operation and, as such,
the client will receive a NFSERR_BADSESSION reply when the lease
has expired for these RPCs. The client will then call nfscl_recover()
to handle the NFSERR_BADSESSION reply. However, for the expired lease
case, the first reclaim Open will fail with NFSERR_NOGRACE.
This patch recognizes this case and calls nfscl_expireclient()
to handle the recovery from an expired lease.
This patch only affects NFSv4.1/4.2 mounts when the lease
expires on the server, due to a network partitioning that
exceeds the lease duration or similar.

Recent discussion on the nfsv4@ietf.org mailing list confirmed
that an NFSv4 server should reply to an RPC in less than 1second.
If an NFSv4 RPC requires a delegation be recalled,
the server will attempt a CB_RECALL callback.
If the client is not responsive, the RPC reply will be delayed
until the callback times out.
Without this patch, the timeout is set to 4 seconds (set in
ticks, but used as seconds), resulting in the RPC reply taking over 4sec.
This patch redefines the constant as being in milliseconds and it
implements that for a value of 800msec, to ensure the RPC
reply is sent in less than 1second.
This patch only affects mounts from clients when delegations
are enabled on the server and the client is unresponsive to callbacks.
