Minor style and simplification cleanups

Browse Source 
This patch does various minor style and simplification cleanups, fixing things
detected by tools such as go vet, gofmt -s, and golint.

There are no functional changes, this change is purely cosmetic, but will
enable us to run those tools more regularly now that their output is clean.
