The state-tracking of WAL reading in various places was pretty messy, mostly because the ancient physical-replication WAL reading code wasn't using the XLogReader abstraction. This led to some untidy code. Make it prettier by creating two additional supporting structs, WALSegmentContext and WALOpenSegment which keep track of WAL-reading state. This makes code cleaner, as well as supports more future cleanup.
