Go through and fix a bunch of places where character strings were being interpreted as format strings. Most of these changes are solely to make compiling with -Wsecurity and -Wformat=2 happy, and were not
actual problems, per se.  I also added format attributes to any printf wrapper functions I found that didn't have them.  -Wsecurity and -Wmissing-format-attribute added to --enable-dev-mode.
