[libvirt] [PATCH 1/2] test: Refactor setting of dummy error handlers



Multiple tests need to register a function to quiesce errors from
libvirt when using a connection and doing negative tests. Each of those
tests had a static function to do so. This can be replaced by a utility
function that enables the errors when debug is enabledd.

This patch adds virtTestQuiesceLibvirtErrors() and refactors test that
use private handlers.
