Dmitry V. Levin a940d1a60f printstr: rename to printstrn, add printstr as a thin wrapper
As about half of all printstr uses cases are invocations with the last
argument set to -1, create a dedicated function for this use case.

* defs.h (printstr): Rename to printstrn.  All callers updated.
(printstr): New static inline function.  All callers updated.
