Subject: [PATCH] Update TravisCI to goclean script.

This commit causes TravisCI to run several tools on each pull request and
commit to help ensure the code quality remains high.  This includes gofmt,
goimports, golint, go vet, the race detector, and coverage stats.

Also, it instructs TravisCI to use nicer container-based builds.
