This changes the LOG macro to be varadic removing the need for all callsites to have double bracketing and allows for future improvement on how we use the logging macros. The callsites were changed with coccinelle and the changes checked by hand. Compile tested for several frontends but not all. A formatting annotation has also been added which allows the compiler to check the parameters and types passed to the logging.
