Subject: [PATCH v6 1/8] Refactor: pg_waldump: Move some declarations to new
pg_waldump.h
This change prepares for a second source file in this directory to
support reading WAL from tar files. Common structures, declarations,
and functions are being exported through this include file so
they can be used in both files.
