pg_waldump: Preparatory refactoring for tar archive WAL decoding.
Several refactoring steps in preparation for adding tar archive WAL
decoding support to pg_waldump:
- Move XLogDumpPrivate and related declarations into a new pg_waldump.h
header, allowing a second source file to share them.
- Factor out required_read_len() so the read-size calculation can be
reused for both regular WAL files and tar-archived WAL.
- Move the WAL segment size variable into XLogDumpPrivate and rename it
to segsize, making it accessible to the archive streamer code.
