Move DeleteAfterReboot, Move, and ReplaceFile to base namespace

Rename ReplaceFileAndGetError (only used once) to ReplaceFile (used 5 times) and have each of those callers specify NULL for the output error if they don't care.

Remove InsertBeforeExtension from file_util.cc which seems to be unused.
