[MINOR] Resolve a number of miscellaneous build warnings

This change resolves a number of build warnings that have accumulated, before 
2.x. It does not address a large number of deprecation warnings, especially 
related to the Accumulator API. That will happen separately.

Closes #13377 from srowen/BuildWarnings.
