6bbfef9004 Fill sin6_scope_id in sockaddr_in6 before passing it from the kernel to 
userland via routing socket or sysctl.  This eliminates the following
KAME-specific sin6_scope_id handling routine from each userland utility:

 sin6.sin6_scope_id = ntohs(*(u_int16_t *)&sin6.sin6_addr.s6_addr[2]);

This behavior can be controlled by net.inet6.ip6.deembed_scopeid.  This is
set to 1 by default (sin6_scope_id will be filled in the kernel).

504a74fa90 Show the number of times we block waiting for mbufs. 
Machines can stall out because mbufs are low, however sometimes we won't
see "requests denied", instead we see user land processes or kernel threads
blocking waiting for mbufs because they set M_WAIT.  These consumers do not
see errors, only stalling.

Unfortunately until now, netstat did not export this information
so you could have experienced an mbuf shortage and have no way of
seeing it unless you happen to run netstat at the exact time of the
shortage and see "in use" = "max".

By exporting the number of times processes are blocked, we can
effectively see how often non-interrupt context threads are effectively
"denied".

d6d3f01e0a Merge the projects/pf/head branch, that was worked on for last six months, 
into head. The most significant achievements in the new code:

 o Fine grained locking, thus much better performance.
 o Fixes to many problems in pf, that were specific to FreeBSD port.

New code doesn't have that many ifdefs and much less OpenBSDisms, thus
is more attractive to our developers.

  Those interested in details, can browse through SVN log of the
projects/pf/head branch. And for reference, here is exact list of
revisions merged:

09fe63205c - Updated TOE support in the kernel. 
- Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs.
  These are available as t3_tom and t4_tom modules that augment cxgb(4)
  and cxgbe(4) respectively.  The cxgb/cxgbe drivers continue to work as
  usual with or without these extra features.

- iWARP driver for Terminator 3 ASIC (kernel verbs).  T4 iWARP in the
  works and will follow soon.

Build-tested with make universe.

30s overview
============
What interfaces support TCP offload?  Look for TOE4 and/or TOE6 in the
capabilities of an interface:
# ifconfig -m | grep TOE

Enable/disable TCP offload on an interface (just like any other ifnet
capability):
# ifconfig cxgbe0 toe
# ifconfig cxgbe0 -toe

Which connections are offloaded?  Look for toe4 and/or toe6 in the
output of netstat and sockstat:
# netstat -np tcp | grep toe
# sockstat -46c | grep toe

6aa83769fd After r232745, which makes sure __bswap16(), ntohs() and htons() return 
__uint16_t, we can partially undo r228668.

Note the remark "Work around a clang false positive with format string
warnings and ntohs macros (see LLVM PR 11313)" was actually incorrect.

Before r232745, on some arches, the ntohs() macros did in fact return
int, not uint16_t, so clang was right in warning about the %hu format
string.

07b202a847 Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to 
get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.

Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang       (disables -Werror)
- NO_WCAST_ALIGN.clang  (disables -Wcast-align)
- NO_WFORMAT.clang	(disables -Wformat and friends)
- CLANG_NO_IAS		(disables integrated assembler)
- CLANG_OPT_SMALL	(adds flags for extra small size optimizations)

As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf!  For clang, use the following:

CC=clang
CXX=clang++
CPP=clang-cpp

b3608ae18f Replace index() and rindex() calls with strchr() and strrchr(). 
The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.
