CreateOverwriteContrecordRecord(), UpdateFullPageWrites(), PerformRecoveryXLogAction(), and CleanupAfterArchiveRecovery() are moved somewhat later in StartupXLOG(). This is preparatory work for a future patch that wants to allow recovery to end at one time and only later start to allow WAL writes. To do that, it's necessary to separate code that has to do with allowing WAL writes from other things that need to happen simply because recovery is ending, such as initializing shared memory data structures that depend on information that might not be accurate before redo is complete. This commit does not achieve that goal, but it is a step in that direction. For example, there are a few different bits of code that write things into WAL once we have finished recovery, and with this change, those bits of code are closer to each other than previously, with fewer unrelated bits of code interspersed.
