Description:
------------
As with many other things, SQLite have very limited support for collations and relies on the host application to implement anything non trivial [1]. For example, an Unicode collations (like accent insensitive collations, for example) will have to be implemented in the application.

I would like to add a PDO_sqlite::sqliteCreateCollation() using the same technique as PDO_sqlite::sqliteCreateFunction() and PDO_sqlite::sqliteCreateAggregate(): allow the application to register a PHP callback as a new collation.

[1] http://www.sqlite.org/faq.html#q18

Test script:
---------------
$db = new pdo('sqlite::memory:');

$db->sqliteCreateCollation('MYCOLLATE', function($a, $b) { return strnatcmp($a, $b); });

// This will return results in the natural order ("P1", "P2", "P10").
$result = $db->query('SELECT name FROM foobar ORDER BY name COLLATE MYCOLLATE');

Request #60871 is related.  It adds the same functionality to the SQLite3 class (not PDO).
