This patch changes mac80211's Kconfig/Makefile to:
* select between the PID and the SIMPLE rate control
algorithm as default
* always allow tri-state for the rate control algorithms,
building those that are selected 'y' into the mac80211
module (if that is a module, otherwise all into the kernel)
* force the default rate control algorithm to be built into
mac80211
It also makes both rate control algorithms proper modules again
with MODULE_LICENSE etc.
Only if EMBEDDED is the user allowed to select "NONE" as default
which will cause no algorithm to be selected, this will work
only when the driver brings one itself (e.g. iwlwifi drivers).

Add a new rate control algorithm based on a PID controller. It samples the
percentage of failed frames over time, feeds the result into the controller and
uses its output to control the TX rate.

Move some code out of rc80211_simple since it's probably needed for all rate
selection algorithms, and fix iwlwifi accordingly. While at it, clean up the
rate_control_get_rate() interface.

Too frequently people do not have module autoloading enabled
or fail to install the rate control module correctly, hence
their hardware probing fails due to no rate control algorithm
being available. This makes the 'simple' algorithm built into
the mac80211 module unless EMBEDDED is enabled in which case
it can be disabled (eg. if the wanted driver requires another
rate control algorithm.)

Removes the management interface since it is only required
for hostapd/userspace MLME, will not be in the final tree
at least in this form and hostapd/userspace MLME currently
do not work against this tree anyway.

I think these can go with rate control just as well and it makes
ieee80211.c more readable.
