Refactor some repetitive SLRU code
Functions to bootstrap and zero pages in various SLRU callers were
fairly duplicative. We can slash almost two hundred lines with a couple
of simple helpers:
- SimpleLruZeroAndWritePage: Does the equivalent of SimpleLruZeroPage
followed by flushing the page to disk
- XLogSimpleInsertInt64: Does a XLogBeginInsert followed by XLogInsert
of a trivial record whose data is just an int64.
