mac80211: better rate control algorithm selection
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).
