error: Functions to report warnings and informational messages

Add warn_report(), warn_vreport() for reporting warnings, and
info_report(), info_vreport() for informational messages.

These are implemented them with a helper function factored out of
error_vreport(), suitably generalized. This patch makes no changes
to the output of the original error_report() function.
