Sam Leffler 47ee60ebbe Regulatory fixups: 
o add missing channel flags for ECM, indoor, and outdoor constraints
o use HT capabilities to short-circuit HT20/HT40 channel construction
o rewrite 1/2 and 1/4 width channel handling yet again; previously
  we assumed there was a full-width version of the channel in the
  calibration table but that's not always true (e.g. for the Public
  Safety Band), now we first check the calibration table for the
  exact channel we want then fall back to the heuristics we used before
o fix HT channel construction; wasn't adjusting band edges for HT40
  channel bandwidth requirements
