When set, this bit causes the EXPLAIN QUERY PLAN output to show the idxNum
value in hex rather than in decimal. This is purely a debugging aid.

in a separately allocated Subquery object. This reduces the memory requirements
for SrcItem and makes the code run faster. It also provides an expansion path
for subquery processing that does not burden simple queries. The current
checking mostly works, but there are still issues that need to be tracked
down and fixed.

be more descriptive of what it contains, and ensures that a subroutine is
not inlines so that sqlite3WhereBegin() runs slightly faster.
