This patch adds the ability to specify a RelFileNode and optional BlockNum to limit output of
pg_waldump records to only those which match the given criteria. This should be more performant
than `pg_waldump | grep` as well as more reliable given specific variations in output style
depending on how the blocks are specified.

This currently affects only the main fork, but we could presumably add the option to filter by fork
as well, if that is considered useful.
