Merge branch 'fix-printf'
Quentin Monnet says:
====================
Because the "__printf()" attributes were used only where the functions are
implemented, and not in header files, the checks have not been enforced on
all the calls to printf()-like functions, and a number of errors slipped in
bpftool over time.
This set cleans up such errors, and then moves the "__printf()" attributes
to header files, so that the checks are performed at all locations.
