18e5607211 New opcode OP_ChngCntRow used to output the result of PRAGMA change_count. 
Only this new opcode, and not OP_ResultRow, checks for foreign key errors.
Faster performance, and now also works with RETURNING.

2053f313bf Lexer and grammar rules for a RETURNING clause on DELETE/INSERT/UPDATE. 
Actually making this work, though, will involve a lot more code which will
likely slow down processing for the common case where there is no
RETURNING clause.  Furthermore, RETURNING seems to be of limited usefulness
and it is not standard SQL.  So we abandon it here.  These experimental
changes are parked in a branch as an historical reference.  If circumstances
changes, we might take up the cause again some day.

Have a single such list for infrequently used sub-objects is more efficient
than doing an a separate check for each kind of sub-object.

37114fbfcc Change the unions of the Table.addColOffset field from characters to bytes. 
This makes the query that implements ALTER TABLE ADD COLUMN more complex and
slightly slower, but also makes CREATE TABLE statement parsing faster by
avoiding a call to sqlite3UtfCharLen().  Since, CREATE TABLE parsing is far
more common than ALTER TABLE, this is a net win for performance.
