first round of commits for proper 11b/g protection support:

- use the newly introduced ieee80211_get_rts() and
  ieee80211_get_cts_to_self() functions.
- use CTS-to-self instead of RTS/CTS to protect OFDM frames in
  a mixed 11b/g BSS.
- make sure multicast frames are sent using CCK modulation.

remove support for 5GHz radios in ral(4) RT2560 and ural(4).
i'm not aware of any such adapters on the market and 11a code
is known to be broken.

some cleanup while i'm here.
