Make dblink interruptible, via new libpqsrv APIs.
This replaces dblink's blocking libpq calls, allowing cancellation and
allowing DROP DATABASE (of a database not involved in the query). Apart
from explicit dblink_cancel_query() calls, dblink still doesn't cancel
the remote side. The replacement for the blocking calls consists of
new, general-purpose query execution wrappers in the libpqsrv facility.
Out-of-tree extensions should adopt these.
The original commit d3c5f37dd543498cc7c678815d3921823beec9e9 did not
back-patch. Back-patch now to v16-v13, bringing coverage to all supported
versions. This back-patch omits the orignal's refactoring in postgres_fdw.
