libpq-be-fe-helpers.h: wrap new cancel APIs
Commit 61461a300c1c introduced new functions to libpq for cancelling
queries. This commit introduces a helper function that backend-side
libraries and extensions can use to invoke those. This function takes a
timeout and can itself be interrupted while it is waiting for a cancel
request to be sent and processed, instead of being blocked.
This replaces the usage of the old functions in postgres_fdw and dblink.
Finally, it also adds some test coverage for the cancel support in
postgres_fdw.
