Back-patch bgworker API changes to 9.3.
Commit 7f7485a0cde92aa4ba235a1ffe4dda0ca0b6cc9a made these changes
in master; per discussion, backport the API changes (but not the
functional changes), so that people don't get used to the 9.3 API
only to see it get broken in the next release. There are already
some people coding to the original 9.3 API, and this will cause
minor breakage, but there will be even more if we wait until next
year to roll out these changes.
