Python 3 no longer doesn't support encoding/decoding hexadecimal numbers using
the `str.format` method. The backwards compatible new method (using the
binascii module/methods) is a comparable means of converting to/from
hexadecimal format.
In short, the functional change is the following:
* `foo.decode('hex')` -> `binascii.unhexlify(foo)`
* `foo.encode('hex')` -> `binascii.hexlify(foo)`
While here, move the dpkt import in `cryptodev.py` down per PEP8, so it comes
after the standard library provided imports.

Summary:
PowerPC kernels are fully position independent, just like kernel modules.
The same fixups that are done for modules therefore need to be done to the
kernel, else symbol resolution in, e.g., DTrace, cannot resolve the kernel
symbols, so only addresses in the kernel are printed, while kernel module
symbols are printed.
Test Plan:
Run lockstat on powerpc64. Note symbols are resolved for kernel and
modules.

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"
in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header
pollution substantially.
EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).
As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions. The remainder of the patch addresses
adding appropriate includes to fix those files.
LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by
sys/mutex.h since r326106 (but silently protected by header pollution prior
to this change).
No functional change (intended). Of course, any out of tree modules that
relied on header pollution for sys/eventhandler.h, sys/lock.h, or
sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.
Currently such routes are added with a link-level IFA, which is
plain wrong. Only after the insertion they get fixed by the special
link_rtrequest() ifa handler. This behaviour complicates routing code
and makes ifa selection more complex.
Streamline this process by explicitly moving link_rtrequest() logic
to the pre-insertion rt_getifa_fib() ifa selector. Avoid calling all
this logic in the loopback route case by explicitly specifying
proper rt_ifa inside the ifa_maintain_loopback_route().§

FDT data is sometimes used to configure usb devices which are hardwired into
an embedded system. Because the devices are instantiated by the usb
enumeration process rather than by ofwbus iterating through the fdt data, it
is somewhat difficult for a usb driver to locate fdt data that belongs to
it. In the past, various ad-hoc methods have been used, which can lead to
errors such applying configuration that should apply only to a hardwired
device onto a similar device attached by the user at runtime. For example,
if the user adds an ethernet device that uses the same driver as the builtin
ethernet, both devices might end up with the same MAC address.
These changes add a new usb_fdt_get_node() helper function that a driver can
use to locate FDT data that belongs to a single unique instance of the
device. This function locates the proper FDT data using the mechanism
detailed in the standard "usb-device.txt" binding document [1].
There is also a new usb_fdt_get_mac_addr() function, used to retrieve the
mac address for a given device instance from the fdt data. It uses
usb_fdt_get_node() to locate the right node in the FDT data, and attempts to
obtain the mac-address or local-mac-address property (in that order, the
same as linux does it).
The existing if_smsc driver is modified to use the new functions, both as an
example and for testing the new functions. Rpi and rpi2 boards use this
driver and provide the mac address via the fdt data.

Apparently, there is more code trying to call pmap_remove() early,
mostly to free preloaded memory. Instead of moving all deallocations
to the point where a scheduler is initialized, add missed setup of
thread0 di init at hammer_time().
The code in pmap_delayed_invl_start_u() is modified to not ever take
the thread lock if the thread priority is less or equal to PVM. Since
thread0 starts at priority 0, and then is reset to PVM at
proc0_init(), this eliminates taking the thread lock during early
boot.
While there, fix off by one in comparision of the base priority.

The `zfs userspace` squashes all entries with unresolved numeric

Fix this by falling to a numerical comparison when either one
of string values is not found. This then compares any numerical
values after all with a name resolved.

It was found during building llvm that the page pv lock pool was seeing very
high contention. Since the pmap is already NUMA aware, it was surmised that
the domains were referencing similar pages in the different domains. This
reduces contention to the point of noise in a lockstat(8) run (~51% down to
under 5%), reducing build times by up to 20%.
This doesn't do a perfect domain alignment, just a best-guess based on
hardware available, that the domain is roughly specified in the upper bits
of the PA. Trying to be more clever would more than likely result in
reduced performance just on the work needed.

memguard(9) wants to avoid reuse of freed addresses for as long as
possible. Previously it maintained a racily updated cursor which was
passed to vmem_xalloc(9) as the minimum address. However, vmem will
not in general return the lowest free address in the arena, so this
trick only really works until the cursor has wrapped around the first
time.

This is described in the vmem paper: "directs vmem to use the next free
segment after the one previously allocated." The implementation adds a
new boundary tag type, M_CURSOR, which is linked into the segment list
and precedes the segment following the previous M_NEXTFIT allocation.
The cursor is used to locate the next free segment satisfying the
allocation constraints.
This implementation isn't O(1) since busy tags aren't coalesced, and we
may potentially scan the entire segment list during an M_NEXTFIT
allocation.

When we are checking the status of the fingerprint on a vnode using the
per-MAC-policy syscall, we do not need an exclusive lock on the vnode.
Even if there is more than one thread requesting the status at the same time,
the worst we can end up doing is processing the file more than once.
This can potentially be improved in the future with offloading the fingerprint
evaluation to a separate thread and blocking until the update completes. But
for now the race is acceptable.
