Add wal_recycle and wal_init_zero GUCs.
On at least ZFS, it can be beneficial to create new WAL files every time and not to bother zero-filling them. Since it's not clear which other filesystems might benefit from one or both of those things, add individual GUCs to control those two behaviors independently and make only very general statements in the docs.
