Fixup handling of roaming and xmit parameters to support 1/2 and 1/4-width channel modes: o usurp 'h' mode flag for half-width channels o add 'q' mode flag for quarter-width channels o rewrite rate parameter parsing to handle fractional values o merge mode loops to eliminate ordering assumptions o replace 0x80 with IEEE80211_RATE_MCS
