b808d77771 Faster implementation for sqlite3VdbeIntValue() and sqlite3VdbeRealValue().

34d04d64f0 Ensure that the sqlite3_value_text() interface returns a buffer that is long 
enough to hold the complete string plus the zero terminator even when the
input is a zeroblob.  Fix for a problem detected by OSS-Fuzz.

cb3cabd01b Refactor the sqlite3BtreeKey() and sqlite3BtreeData() internal interfaces 
into sqlite3BtreePayload() and sqlite3BtreePayloadChecked(), respectively.
This is a continuation of the optimization started by check-in
[2d831074cf].  The result is a slightly smaller and faster binary.

fc7f27b9d2 Change the way TK_SELECT_COLUMN is handled so that the subquery is only 
generated once even if part of the vector comparison is used for indexing
and the other part is now.  This change also is a pathway to vector assignment
in UPDATE statements.

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.
