drh 8c74a8ca5b Fix for ticket #136: Added the OP_RenameCursor VDBE instruction and used it 
to make cursor numbers right on nested subqueries.  Also added OP_Gosub and
OP_Return but have not actually used them for anything yet. (CVS 727)

drh 2f2c01e51d Fix for ticket #92: Correct the sqliteExprCompare() function so that is takes 
into account the iTable and iColumn fields of the Expr structure.  Otherwise,

drh 0bb28106be Fix for tickets #32 and #33: Generate the names of the result set early, before 
doing the flattening optimization or evaluating subqueries.  Otherwise, the
result set column names are generated incorrectly or after they are needed. (CVS 553)

drh 417be79cd1 VIEWs are bound to tables when they are used, not when they are first 
entered.  This works around the problem of what to do if a table is deleted
that a view refers to. (CVS 415)
