Similar to r260026, disable warning about unused functions for
ieee80211_adhoc.c, ieee80211_hostap.c and ieee80211_sta.c.

MFC r260026:

Disable warning about unused functions for ieee80211_crypto.c and
ieee80211_mesh.c for now.

Allow IEEE80211_SUPPORT_SUPERG to be defined _and_ have a working wlan
module.

Fix 'make depend'.

Fix the situation where net80211 is built with IEEE80211_SUPPORT_TDMA but a module
is used.

Although the module _builds_, it fails to load because of a missing symbol from
ieee80211_tdma.c.

Specifics:

* Always build ieee80211_tdma.c in the module;
* only compile in the code if IEEE80211_SUPPORT_TDMA is defined.

Fix a typo, it is MPDU not MDPU.

Fix an undefined behaviour if the desired ratectl algo is not available.
This can happen if the algos are built as modules but are not loaded. If
the selected ratectl algo is not available, try to load it (The load
module functions does nothing currently). Add a dummy ratectl algo which
always selects the first available rate. Use that one if the desired algo
is not available.

Add ieee80211_{amrr,rssadapt}.c.

MFC after: 1 month

net80211 rate control framework (net80211 ratectl).

This framework allows drivers to abstract the rate control algorithm and
just feed the framework with the usable parameters. The rate control
framework will now deal with passing the parameters to the selected
algorithm. Right now we have AMRR (the default) and RSSADAPT but there's
no way to select one with ifconfig, yet.
The objective is to have more rate control algorithms in the net80211
stack so all drivers[0] can use it. Ideally, we'll have the well-known
sample rate control algorithm in the net80211 at some point so all
drivers can use it (not just ath).

[0] all drivers that do rate control in software, that is.

adds opt_inet6.h to fix a error during compiling wlan as a module.

Reviewed by: sam

After r193232 rt_tables in vnet.h are no longer indirectly dependent on
the ROUTETABLES kernel option thus there is no need to include opt_route.h
anymore in all consumers of vnet.h and no longer depend on it for module
builds.

Remove the hidden include in flowtable.h as well and leave the two
explicit #includes in ip_input.c and ip_output.c.

update for r192468 (monitor mode changes)

Submitted by: jkim

Rather than using hidden includes (with cicular dependencies),
directly include only the header files needed. This reduces the
unneeded spamming of various headers into lots of files.

For now, this leaves us with very few modules including vnet.h
and thus needing to depend on opt_route.h.

add ddb support (default to off unless built with the kernel)

Per email to arch@ a little while ago (that was greeted with silence),
prefer the more common > ${.TARGET} over > opt_foo.h in modules

enable IEEE80211_AMDPU_AGE by default

Multi-bss (aka vap) support for 802.11 devices.

Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral). Also there
no longer are separate wlan_scan* modules; this functionality is now
bundled into the wlan module.

Add new files in the net80211 changes.

Add a value to the define I forgot, for the purity's sake.

Now that we have COMPAT_FREEBSD6 officially, use it from opt_compat.h.

Let modules use the kernel's opt_*.h files if built along with
the kernel by wrapping all targets for fake opt_*.h files in
.if defined(KERNBUILDDIR). Thus, such fake files won't be
created at all if modules are built with the kernel.

Some modules undergo cleanup like removing unused or unneeded
options or .h files, without which they wouldn't build this way
or the other.
