Fix non-constant format string in calls to Printf-like functions

Browse Source 
In a few places, we call Printf-like functions, but for the format we
use either non-format messages (which is not tidy, but okay), or
variable messages (which can be problematic if they contain %-format
directives).

The patch fixes the calls by either moving to Print-like functions, or
using `Printf("%s", message)` instead.

These were found by a combination of `go vet` (which complains about
"non-constant format string in call"), and manual inspection.
