Avoid use of printf()/fprintf()

Use one of the following functions where appropriate:

* puts() (whenever we print hard coded strings to stdout)
* fputs() (whenever we print hard coded strings to a stream)
* putchar() (whenever we print a single character to stdout)
* fputc() (whenever we print a single character to a stream)
* strncpy() (whenever we copy hard coded strings to a buffer)

This removes the overhead introduced by the format string parser and
reduces the number of false positive C-format strings spotted by
xgettext(1)'s heuristics.
