The pciconf command fails to emit newlines when particular ecap field
values are seen. Fix them up. This has been seen on several systems at
$JOB. The documentation for PCI capabilities says that capability
type 0 should not be used once the spec for PCI capabilities was
published, but that seems more wishful-thinking than reality. pciconf
also chooses not to print fields related to field values that are
zero, but it seems several of these fields are zero on actual
hardware.

This simplifies life a bit, by not requiring us to repease the
declaration for every file where we want static probe points.
It also makes the gcc6 build happy.
There are several NFSv4.1/4.2 server operation functions which
have unneeded checks for the NFSv4 root being set up.
The checks are not needed because the operations always follow
a Sequence operation, which performs the check.
This patch deletes these checks, simplifying the code so
that a future patch that fixes the checks to conform with
RFC5661 Sec. 2.6 will be less extension.

The current WPA build assumes a flat namespace. However the latest sources
from w1.fi now have a duplicate config.c, in two separate subdirectories.
The flat namespace will overwrite config.o with the output from the most
recently modified config.c, of which there are two of them.
This commit resolves this problem by building each component in
wpa's src subdirectory tree into its own .a archive, just as the w1.fi
upstream build as used by the port does. The advantages of this approach
are:
1. Duplicate source file names, i.e. config.c in the wpa_supplicant
direcory and another config.c in src/utils in the next wpa
will result in both compiles writing to the same .o file.
2. This restructure simplifies maintanence. A develper needs only to add
new files as identified by git status in the vendor branch to the
appropriate Makefile within the usr.sbin/wpa tree. This also reduces
time required to prepare a new import and should reduce error.
3. The new wpa build structure more closely represents the build as
performed by the upstream tarball.
This is in preparation for the next wpa update from w1.fi.

When PTI is enabled, we may have been on the trampoline stack when iret
faults. So, we have to switch back to the regular stack before
re-entering trap().
trap() has the somewhat strange behaviour of re-enabling interrupts when
handling certain kernel-mode execeptions. In particular, it was doing
this for exceptions raised during execution of iret. When switching
away from the trampoline stack, however, the thread must not be migrated
to a different CPU. Fix the problem by simply leaving interrupts
disabled during the window.

Paste's man page contains an example for a reimplementation of
nl(1). This example uses the command line
sed = myfile | paste -s -d '\t\n' - -
in order to concatenate consecutive lines with an intervening tab.
However, the way the example uses the switches -s and -d and two `dash`
input files is redundant. There are in fact two equivalent but simpler
ways to achieve the desired result:
sed = myfile | paste -s -d '\t\n' -
uses the same style as the previous example, while
sed = myfile | paste - -
is arguably even simpler and illustrates the final sentence of the

Even if the clock is flagged with AW_CLK_SET_PARENT the current parent
freq might be enough to get a correct divisor.
So test first if we can get the expected freq before changing the parent
freq.
The functionality to detect a newly created link after processing a
single packet is decoupled from the packet processing. Every new
packet is processed asynchronously and will reset the indicator, hence
the function is unusable. I made a Google search for third party code,
which uses the function, and failed to find one.
That's why the function should be removed: It unusable and unused.
A much simplified API/ABI will remain in anything below 14.

Changes:
1. add spinlock to bw_meter
If two contexts read and modify bw_meter values
it might happen that these are corrupted.
Guard only code fragments which do read-and-modify.
Context which only do "reads" are not done inside
spinlock block. The only sideffect that can happen is
an 1-p;acket outdated value reported back to userspace.
2. replace all locks with a single RWLOCK
Multiple locks caused a performance issue in routing
hot path, when two of them had to be taken. All locks
were replaced with single RWLOCK which makes the hot
path able to take only shared access to lock most of
the times.
All configuration routines have to take exclusive lock
(as it was done before) but these operation are very rare
compared to packet routing.
3. redesign MFC expire and UPCALL expire
Use generic kthread and cv_wait/cv_signal for deferring
work. Previously, upcalls could be sent from two contexts
which complicated the design. All upcall sending is now
done in a kthread which allows hot path to work more
efficient in some rare cases.
4. replace mutex-guarded linked list with lock free buf_ring
All message and data is now passed over lockless buf_ring.
This allowed to remove some heavy locking when linked
lists were used.
The Linux client is now attempting to use the Secinfo_no_name
operation for NFSv4.1/4.2 mounts. Although it does not seem to
mind the NFSERR_NOTSUPP reply, adding support for it seems
reasonable.
I also noticed that "savflag" needed to be 64bits in
nfsrvd_secinfo() since nd_flag in now 64bits, so I changed
the declaration of it there. I also added code to set "vp" NULL
after performing Secinfo/Secinfo_no_name, since these
operations consume the current FH, which is represented
by "vp" in nfsrvd_compound().
Fixing when the server replies NFSERR_WRONGSEC so that
it conforms to RFC5661 Sec. 2.6 still needs to be done
in a future commit.
