274245c881 Create a mechanism for looking up a device_t associated with an ofw/fdt
xref handle, and for registering that association.  Also use the same data
for faster translations between node and xref handles.

Now when fdt properties contain &othernode references, a driver can find
the device instance that corresponds to &othernode, and thus can use
interfaces provided by that instance.

e562d2dad7 Enable lock annotations on HEAD when using Clang.

b2d6fddee7 Add lock annotations to <sys/cdefs.h>.
Clang has support for annotating mutexes and code that uses mutexes to
validate certain aspects of thread safety:

- Whether acquiring/releasing locks is done properly (e.g., whether you
  unlock a mutex before leaving a function).
- Whether a lock is held while reading/writing data from/to memory.

Analysis is performed at the function level. Functions can be annotated
to indicate they:

- (try to) pick up a lock,
- release a lock,
- can only be called when (not) holding a lock,
- assert that a lock is held.

Variables and structure members can be annotated to indicate that they
are guarded by a certain lock. In C++, these annotations can refer
to both global variables, but also other class/structure members. In C,
it is only possible to refer to global variables.

This change adds wrappers for the annotations used by Clang to
<sys/cdefs.h>. They currently have no effect, but this is on purpose.
This change will be merged back to FreeBSD 9 and 10, which means we can
safely experiment with these annotations on HEAD without making it
harder to port changes back.

c26544aa7f Make SOCK_RAW sockets to be truly raw, not modifying received and sent
packets at all. Swapping byte order on SOCK_RAW was actually a bug, an
artifact from the BSD network stack, that used to convert a packet to
native byte order once it is received by kernel.

Other operating systems didn't follow this, and later other BSD
descendants fixed this, leaving us alone with the bug. Now it is
clear that we should fix the bug.

for removal are:
- No code in tree uses this possibility.
- The documentation ifmib(4) doesn't say that such possibility
  exist. The example provided in manual page only reads data.
- On many interfaces the feature simply doesn't work, since they
  do accounting in hardware, and overwrite if_data on tick.

4c98655ece The "SUB" instruction used in getcc() actually does 'x -= y' so use the
proper constraint for 'x'. The "+r" constraint indicates that 'x' is an

- use proper __FreeBSD_version check and more importantly check for __am64__
  to be defined.  Whether the FreeBSD(_version) checks are needed is a
  different question.
- cast uint64_t to uintmax_t and use %jx for printing.

Note: there are more values that could be printed in that status function
	but leave that for the future;  printf doesn't seem to be the right
	way to do it anyway.
Note: there is more breakage related to i40e_allocate_dma*() having
