an sqlite3 connection pointer, which the xBestIndex method might not have
access to.

column X. location(X) returns NULL if X is not an ordinary table column or
if SQLite cannot figure out the location because it is using a covering index.

no function calls or subqueries. This is a partial reversal of
check-in [c9104b59]. Co-routines are still preferred if the outer
query has a complex result set, but for simple results sets, query flattening
is used. Check-in [4464f40ccd7] is completely backed
out due to this change.

sqlite3ExprListAppend(). Include a new test case that shows this sometimes
does happen.

SQLITE_CONFIG_SMALL_MALLOC configuration option that provides a hint to SQLite
that large memory allocations should be avoided.
