John C. Vernaleo c2ed8ffc2b Add goclean.sh script from btcd.
This commit corrects various things found by the static checkers
(comments, unkeyed fields, return after some if/else).

Add generated files and legacy files to the whitelist to be ignored.

Catch .travis.yml up with btcd so goclean can be run.
