nbtree: Rename BT_RESERVED_OFFSET_MASK.
The mask was added by commit 8224de4f, which introduced INCLUDE nbtree
indexes. The status bits really were reserved initially. We now use 2
out of 4 of the bits for additional tuple metadata, though. Rename the
mask to BT_STATUS_OFFSET_MASK.
Also consolidate related nbtree.h code comments about the format of
pivot tuples and posting list tuples.
