Logical replication support for TRUNCATE

Browse Source 
Update the built-in logical replication system to make use of the
previously added logical decoding for TRUNCATE support.  Add the
required truncate callback to pgoutput and a new logical replication
protocol message.

Publications get a new attribute to determine whether to replicate
truncate actions.  When updating a publication via pg_dump from an older
version, this is not set, thus preserving the previous behavior.
