-  Multiple bug fixes to the row value logic that was introduced in version 3.15.0.

     syntax error.  Ticket 
     2f1b168ab4d4844.

     in the built-in instr() function.

Hashes:
 
- SQLITE_SOURCE_ID: "2016-11-28 19:13:37 bbd85d235f7037c6a033a9690534391ffeacecc8"
- SHA1 for sqlite3.c: 06d77b42a3e70609f8d4bbb97caf53652f1082cb
Changes carried forward from version 3.15.1 (2016-11-04):
-  Added SQLITE_FCNTL_WIN32_GET_HANDLE file control opcode.
-  Fix the VACUUM command so that it spills excess content to disk rather
     than holding everything in memory, and possible causing an out-of-memory
     error for larger database files.  This fixes an issue introduced by
     version 3.15.0.
-  Fix a case (present since 3.8.0 - 2013-08-26) 
     where OR-connected terms in the ON clause of a LEFT JOIN
     might cause incorrect results.  Ticket
     34a579141b2c5ac.
-  Fix a case where the use of row values in the ON clause of a LEFT JOIN
     might cause incorrect results.  Ticket
     fef4bb4bd9185ec8f.
Changes carried forward from version 3.15.0 (2016-10-14):
-  Added support for row values.
-  Allow deterministic SQL functions in the WHERE clause of a partial index.
-  Added the "modeof=filename" URI parameter on the unix VFS
-  Added support for SQLITE_DBCONFIG_MAINDBNAME.
-  Added the ability to VACUUM an ATTACH-ed database.
-  Enhancements to the command-line shell:
     
     -  Add the ".testcase" and ".check" dot-commands.
     
-  Added the --new option to the ".open" dot-command, causing
          any prior content in the database to be purged prior to
          opening.
     
 
-  Enhance the fts5vocab virtual table to handle "ORDER BY term" efficiently.
-  Miscellaneous micro-optimizations reduce CPU usage by more than 7%
     on common workloads.  Most optimization in this release has been on the
     front-end (sqlite3_prepare_v2()).
Bug Fixes:
 
-  The multiply operator now correctly detects 64-bit integer overflow
     and promotes to floating point in all corner-cases.  Fix for ticket
     1ec41379c9c1e400.
-  Correct handling of columns with redundant unique indexes when those
     columns are used on the LHS of an IN operator.  Fix for ticket
     0eab1ac759.
-  Skip NULL entries on range queries in indexes on expressions.
     Fix for ticket
     4baa46491212947.
-  Ensure that the AUTOINCREMENT counters in the sqlite_sequence
     table are initialized doing "Xfer Optimization" on "INSERT ... SELECT"
     statements.  Fix for ticket
     7b3328086a5c116c.
-  Make sure the ORDER BY LIMIT optimization 
     (from check-in 559733b09e)
     works with IN operators on INTEGER PRIMARY KEYs.  Fix for ticket
     96c1454c
