cfg80211 API for channels/bitrates, mac80211 and driver conversion
This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.

11 * This regulatory domain control implementation is known to be incomplete

13 * reworked in the not-too-distant future.
14 *
15 * For now, drivers wishing to control which channels are and aren't available
16 * are advised as follows:
17 * - set the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag
18 * - continue to include *ALL* possible channels in the modes registered
19 * through ieee80211_register_hwmode()
20 * - for each allowable ieee80211_channel structure registered in the above
21 * call, set the flag member to some meaningful value such as
22 * IEEE80211_CHAN_W_SCAN | IEEE80211_CHAN_W_ACTIVE_SCAN |
23 * IEEE80211_CHAN_W_IBSS.
24 * - leave flag as 0 for non-allowable channels
25 *
26 * The usual implementation is for a driver to read a device EEPROM to
27 * determine which regulatory domain it should be operating under, then
28 * looking up the allowable channels in a driver-local table, then performing
29 * the above.
