Fixup handling of roaming and xmit parameters to support 1/2 and 1/4-width

Browse Source 
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
