c4645dacfb Merge the latest trunk changes (especially "PRAGMA busy_timeout" and the 
ORDER BY query planner optimizations) into the sessions branch.

7e5418e4a4 Add more bits to the bit vector that is used to disable optimizations for 
built-in test.  Add specific bit patterns to disable ORDER BY using an
index in general and for joins.  Use macros to test for bits in the 
disabled-optimization bit vector, in order to make the code clearer.

097ce2caab Add a bit to the SQLITE_TESTCTRL_OPTIMIZATIONS setting that will disable 
affinity when writing to any index, regardless of whether or not the index
is on a manifestation of a view.  This allows better testing of the fix
