Bug 1283052 - Remove some of the magic around mozconfig detection. r=gps The mozconfig detection logic has bitten us on many occasions in the past. The following changes are made to tentatively improve the situation: - The API is modified such that autodetection of the mozconfig has to be a conscious decision made by the caller, and not triggered any time there is no mozconfig given, which could be a conscious decision of the opposite. - mozinfo.json now stores the actual mozconfig (or lack thereof) used during configure.
