gives machine unique values from the firmware.
* The kernel is more likely to be unique than /bin/ls (but no need to
stuff many megabytes into /dev/random, so hash it).
* Change ordering to give larger variance across reboots to reduce
predictability.
Merge ether_ipfw_chk() and part of bridge_pfil() into
unified ipfw_check_frame() function called by PFIL.
This change was suggested by rwatson? @ DevSummit.
Remove ipfw headers from ether/bridge code since they are unneeded now.
Note this thange introduce some (temporary) performance penalty since
PFIL read lock has to be acquired for every link-level packet.

- Move mwlfw from {amd64,i386}/conf/NOTES to sys/conf/NOTES (mwl(4) is
already present in sys/conf/NOTES).
- Remove duplicate mwl(4) entries from {amd64,i386}/conf/NOTES.
- While here, add a description to the sfxge line in amd64/conf/NOTES.
all in one command, with no permissions race.
2. Simplify the rotation logic by cd'ing into the directory, with a test
to make sure that it succeeds.
3. Remove any files numbered higher than entropy_save_num. This helps when
the user reduces the number, and may be useful for other purposes down
the road.
4. Simplify the rotation logic by first testing the common case (it's a
regular file) then testing if something else exists with the same name
using elif. Also switch from using jot to simpler countdown format.
5. Fix logger lines and error messages to be more consistent, and wrap the
code more consistently in the 80 column range. The "not a regular file"
error message was mistakenly wrapped entirely in "quotes" which caused
logger to include line-wrapping whitespace. Change that to wrap only
the variables in quotes, which is both consistent and works better.
6. Update copyright to reflect the fact that changes were made this year.

For NFSv4 ACLs, this sort of situation would result in duplicated

- Provide missing function that can do hashing of arbitrary sized buffer.
- Refetch lookup3.c and do only minimal edits to it, so that diff between
our jenkins_hash.c and lookup3.c is minimal.
- Add declarations for jenkins_hash(), jenkins_hash32() to sys/hash.h.
- Document these functions in hash(9)

PR submitter suggested adding it to acl(3) instead, but I don't think
pointing ordinary users at section 3 is a good idea.

with multicast bit set. FreeBSD refuses to install such
entries since 9.0, and this broke installations running
Microsoft NLB, which are violating standards.

0 - loader hints in environment only;
1 - static hints only
2 - fallback mode (Dynamic KENV with fallback to kernel environment)
Add kern.hintmode write handler, accept only value 2. That will switch
static KENV to dynamic. So it will be possible to change device hints.

__BEGIN_DECLS and __END_DECLS in cdefs.h take care of the
__cplusplus mangling issues so most of the definitions
were redundant.
In the few places where they were not redundant we should
use BSD style instead of the guards used upstream.

C++ mangling will cause trouble with variables like __rpc_xdr
in xdr.h so rename this to XDR.
While here add proper C++ guards to RPC headers.

warnings in sys/gnu/fs/xfs. The only warnings that still need to be
suppressed are those about array bound overruns of flexible array
members in xfs_dir2_{block,sf}.c, which are too expensive (in terms of
cascading code changes) to fix.
