newblue: add format attributes; fix related warnings
A bug kept us from diagnosing non-constant format strings. Cleaning
those up led to a few custom log functions, which can each be tagged
with a special attribute to get clang to do extended format string
checking.
This CL adds said attribute, and cleans up places where we had incorrect
format strings
