Enable persistent connections for IBMi

'db' => array(
        'driver' => 'IbmDb2',
        'database' => '*LOCAL',
        'username' => 'USER',
        'password' => 'PASSWORD',
        'persistent' => true,

        ),
        'platform_options' => array(
            'quote_identifiers' => false
        )

'persistent' accepts true/false, or can be left out

Fixing a bug that causes fatal error when a RowGateway's primary key were changed directly : refresh the select's where clause after the update query.
[#5256] allow keys with less than maximum supported key length.
fixed coding style.
Was using count($keySizes) and thought !empty($keySizes) would be clearer and missed the '!'.
fixed test, short key should be usable with blowfish.
Also test for all algorithms, just to make sure that key really is short ( < 8).
Test key needs to be shorter than the shortest supported key size, which
is 5 bytes (cast-128). Replaced it with 'four'.
It slipped because somehow on cygwin cast-128 only support 16 bytes.
Unit test ZendTest\Db\Adapter\Driver\Pdo\ResultTest::testCurrent() tests current() returns consistent results
