Refactor to create generic WAL page read callback
Previously we didn’t have a generic WAL page read callback function,
surprisingly. Logical decoding has logical_read_local_xlog_page(), which was
actually generic, so move that to xlogfunc.c and rename to
read_local_xlog_page().
Maintain logical_read_local_xlog_page() so existing callers still work.
As requested by Michael Paquier, Alvaro Herrera and Andres Freund
