After convertion to g_strdup, the helpers now always return success. Remove the return value to simplify the callers. Note that many occurences of these is in the code generated by gendispatch.pl. Since gendispatch aggregates many cases together a incremental conversion would require more invasive changes to gendispatch for the time of coversion which doesn't make sense. Also in many cases the helper was the last place where the 'error:' label was used and thus also those conversions must be included in this patch.

Few events emit optional strings. We need to allocate the container for it first. Note that remote_nonnull_string is used as the type as the internal part of the string is nonnull if the container is present.

Move calls to virTypedParamsSerialize earlier in the event dispatch functions so that we don't have to call 'xdr_free' afterwards. This is possible as virTypedParamsSerialize cleans up after itself if it fails.
