According to SQLite documentation, a database connection handle
is usually returned, even if an error occurs. This behavior has
caused Qt to leak memory when opening a database is failed. Now,
even if sqlite3_open_v2() does not return SQLITE_OK, Qt tries to
release SQLite database handle by calling sqlite3_close().

When an aggregate function is used for a column in a SQL resultset then
it should ensure that the right data type is reported for that column.
This also concerns expressions when the returned column does not map
directly to a table column.

Test included for this.

Documentation for Q_DECLARE_METATYPE and qRegisterMetaType was updated
to mention requirements on registered types and how they can be
circumvented for pointer types with the new macro.

The 'real' datatype should be seen as a QVariant::Double type and not as
a QVariant::String type otherwise it does not get presented correctly
when using a non Qt application to access it.

total number of lines in the license header.

This is a source incompatible change for Q_DECLARE_METATYPE(T*),
which now requires T to be fully defined.

The consequences of this are:
 * Forward declared types can no longer be declared as a metatype.
     (though this is a very uncommon thing to do).

There is a trivial workaround where necessary.

Even though it is stated in the documentation that the SQL driver must
remain valid during the life time of QSqlQuery, there are users who don't
follow the rule. It's common that the destructor of QSqlQuery is called
after the driver is already deleted. This fix checks the validity of
the SQLite driver before QSqliteResult uses it in destructor.

If an ongoing query is not finalized before close function is
called, sqlite driver still tries to close the connection to
sqlite. In this case, sqlite reports an error to sqlite driver
which is not reported to the client. The failure in close causes
connection to sqlite unclosed and memory is not freed. This
fix tries to finalize all queries before close function is called.
The close function should succeed.
