c1fd2cfed2 Make sure the size parameter to read and write VFS methods in the unix VFS 
do not become too big or go negative.  This was not actually possible in the
current code.  The checks are added to make sure some future bug does not
make it possible.

0094f37e1f Avoid calling sqlite3BtreeEnter() in a corner case where the corresponding database handle mutex (sqlite3.mutex) may not be held. This prevents a potential deadlock or crash that can occur if the backup API, shared-cache mode and SQLITE_HAVE_CODEC are all in use.

a9e3fc05f5 Fix some corner case behavior in the new ORDER BY optimization logic. 
Remove the SQLITE_OrderByIdx bit from the 
SQLITE_TESTCTRL_OPTIMIZATIONS mask, since enabling it caused many
TH3 tests to fail when the NO_OPT configuration parameter was engaged,
and since there really isn't any need to turn that optimization off.
The SQLITE_OrderByIdxJoin bit remains.
