MFC r257532 (by adrian):

Fix this build for clang.

MFC r259730:

To avoid having to explicitly test COMPILER_TYPE for setting
clang-specific or gcc-specific flags, introduce the following new
variables for use in Makefiles:

CFLAGS.clang
CFLAGS.gcc
CXXFLAGS.clang
CXXFLAGS.gcc

In bsd.sys.mk, these get appended to the regular CFLAGS or CXXFLAGS for
the right compiler.

MFC r259913:

For libstand and sys/boot, split off gcc-only flags into CFLAGS.gcc.

MFC r259927:

Fix pc98 build, by also forcing COMPILER_TYPE in sys/boot/pc98/boot2's
Makefile.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Fixed missing or broken library dependencies.

Update for vaps:
o do not force monitor mode; the wlanX ifnet must be an ahdemo mode vap
o move channel change work before marking ifnet up to avoid churning
the state machine
o change default ifnet name to "wlan0"

update for recent mesh additions

Approved by: re (kib)

Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.

Authentication and encryption are not implemented.

There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).

A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.

Drivers that support mesh networks right now are: ath, ral and mwl.

More information at: http://wiki.freebsd.org/WifiMesh

Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.

Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.

fix typo

Cleanups to prepare this code for wider use (likely merged into hostapd):
o add (required) cmd line args to specify the set of ifnet's to monitor
for WDS discovery msgs; "any" is a wildcard
o change the default script run on wds vap create to the "null script"
o auto-daemonize; add -f option to force foreground operation
o add -P option for integration with rc.d (implementation missing, tba)
o use syslog; default to log up to LOG_INFO, -t (terse) gives you up to
LOG_ERR, and -v (verbose) gives you up to LOG_DEBUG
o scan for existing vaps on startup to recover existing state
o correct some types

no more need for -p option to wlanwds; it knows how to find the parent now

o remove the -p option; use the %parent pointer sysctl to find the parent ifnet
o remove the -b option; users can just embed the bridge ifnet in the script
o add -j option to create wds vaps on join/rejoin ops

revamp after 1/2 and 1/4 rate changes

for adhoc and ahdemo modes try to find the "bss node": use the bssid
unless it's not setup or zero's; this may not work as the bssid of
the ibss isn't certain to the "right mac address" but for many cases
it is

make -o handling like athstats

o fix identification of ahdemo mode
o split out code to get the bssid for use in the future
o include more information in error diags when unable to collect sta info/stats

simple scripts to demonstrate tdma setup

add tool to calculate air time for 802.11 packets

eliminate hardwired lists; use the media type to autoconfig

use new sysctl to generate a fake radar event

Flush stdout after each line to make piping to another command easier.

o add indirect array for field indices as the # stats is > 127 and doesn't
fit in a signed char
o change default output to something more useful for sta mode
o futz w/ various field names and widths; need to do full pass over this stuff

update for new events

Add new directories, scripts and wlanwds. Introduced with vap support.

Add missing 't'.

Due to the recent "aircrack-ptw" WEP cracking discovery, I thought
that it might be worth fixing a couple of bugs in wesside and making
it use the new cracking technique. I think this enhancement makes
the tool quite usable. It is possible to recover keys in only a
couple of minutes.

* Fix ACKs. Firmware will ACK data [just set the MAC addr correctly].
* Fix RX routines. Process all packets read().
* Use aircrack-ptw [built-in] rather than external aircrack.
* Log data in pcap format so that it may be used by others [e.g. aircrack-ng].
