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
