<li>Added the [PRAGMA foreign_key_check] command.
<li>Added new extended error codes for all SQLITE_CONSTRAINT errors
<li>Added SQL functions [unicode(A)] and [char(X1,...,XN)].



<li>Improved optimization of queries containing aggregate min() or max().
<li>Enhance virtual tables so that they can potentially use an index when
    the WHERE clause contains the IN operator.
<li>Allow indices to be used for sorting even if prior terms of the index
    are constrained by IN operators in the WHERE clause.
<li>Enhance the [PRAGMA table_info] command so that the "pk" column is an
    increasing integer to show the order of columns in the primary key.
