Change the sqlite3BtreeKeySize() interface into sqlite3BtreeIntegerKey() and

make it only work for table btrees. Change sqlite3BtreeDataSize() into
sqlite3BtreePayloadSize() and make it work for all btrees. Combine
sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() into a single
sqlite3BtreePayloadFetch() routine. These changes seem to make the
b-tree interface more rational and they reduce both binary size and
CPU usage.
