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

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.
* Correctly handle -a.
* -A isn't supported.
* Show all closed 1-to-1 and 1-to-many style sockets.
* Show all listening 1-to-many style sockets.
* Use consistent formatting for -W.

starting from netgraph import in 1999.
netstat(8) used pointer to node as node address, oops. That didn't
work, we need the node ID in brackets to successfully address a node.
We can't look into ng_node, due to inability to include netgraph/netgraph.h
in userland code. So let the node make a hint for a userland, storing
the node ID in its private data.

kernel changes than querying the kernel via sysctl (the default), but
useful when investigating crashes or live kernel state via firewire.

otherwise sign extension leads to unlikely values when in the negative

The type used to hold routing statistics is arguably also incorrect.

No plans to MFC this, as it changes the netstat sysctl ABI.

Update netstat to get the correct pointer using kvm_read()
as well.
This not only fixes the ABI problem depending on the kernel
option but also permits the tunable to overwrite the kernel
option at boot time up to MAXFIBS, enlarging the number of
FIBs without having to recompile. So people could just use
GENERIC now.

X-MFC: not possible
Match the bracketing in netstat.
Since the cleanup of MROUTING, ports have broken because they
expect to include <netinet/ip_mroute.h> without including
<sys/queue.h>. Fix breakage at source.
The real fix, of course, is to fix the MROUTING APIs by blowing them
away and replacing them with something else...
