Convert remaining single line fprintf() to warn_report()

Convert any remaining uses of fprintf(stderr, "warning:"...
to use warn_report() instead. This helps standardise on a single
method of printing warnings to the user.

All of the warnings were changed using this command:
  find ./* -type f -exec sed -i 's|fprintf(.*".*warning[,:] |warn_report("|Ig' {} +

The #include lines and chagnes to the test Makefile were manually
updated to allow the code to compile.
