We have several tests that perform multiple sub-actions that are
expected to fail. Asserting that an error occurred, then clearing
it up to prepare for the next action, turned into enough
boilerplate that it was sometimes forgotten (for example, a number
of tests added to test-qmp-input-visitor.c in d88f5fd leaked err).
Worse, if an error is not reset to NULL, we risk invalidating
later use of that error (passing a non-NULL err into a function
is generally a bad idea). Encapsulate the boilerplate into a
single helper function error_free_or_abort(), and consistently
use it.
The new function is added into error.c for use everywhere,
although it is anticipated that testsuites will be the main
client.
