652cc4b6dc Merge all recent changes from trunk, 
including the fix for the OP_SCopy-vs-OP_Copy problem.

a1f7c0a21c Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter 
database corruption, they will set the UnpackedRecord.isCorrupt field and
return 0.  The sqlite3BtreeMovetoUnpacked() routine detects this and returns
SQLITE_CORRUPT, causing the corruption to be reported back to the top-level.

28935364ef If the SQLITE_ENABLE_CURSOR_HINTS macro is defined, then invoke the 
sqlite3BtreeCursorHint() interface to provide hints to the storage engine
about rows that need not be returned.  Hints can be disabled using
SQLITE_TESTCTRL_OPTIMIZATIONS with SQLITE_CursorHints (0x2000).  Cursor
hints are not used by the built-in storage engine of SQLite but might
be useful to applications that provide their own storage engine.  The
current code is work-in-progrss and contains bugs.
