28f17017ee Fix a potential null-pointer dereference and crash in the case where one 
thread is calling sqlite3_column_text() and another thread is calling
sqlite3_step() on the same prepared statement at the same instant.

a7c90c42ea 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.
