[TYPO3-core] Bug 3552: Uninitialized array causes problems in PHP5

This is a CVS patch request
(my first since SVN - could anyone point me to a thread where it has been
discussed how to commit now (i know svn update/commit - just not if we have to
use special branches or whatever)

Bugtracker reference:

When a new section get's added to a Flexform (doesn't matter if it was handcrafted
or made using the TV Flexform-Wizard (Mapper)) it doesn't get added to the flexform
XML in the database instantly.
It rather get's added when the first field's of this section-element get submitted
(meaning on next submit).
This causes a problem with PHP5. While the flexform-field get's checked by t3lib_tcemain
(function "checkValue") a problem get's caused while calling method "checkValue_flex_procInData_travDS"

Here in line 1950 an array-key is accessed which doesn't exist at this moment because
the flexform look still like:

        <sheet index="sDEF">
            <language index="lDEF">
                <field index="field_section">
                    <el index="el">

from this code:

The third passed variable "$dataVAlues_current" is the flexform-xml array which got directly
fetched from the database. As I noticed before the values of the section-element will only be
available in $dataValues and not in the record fetched from DB.

This doesn't cause problems in PHP4 as the error:
"Fatal error: Cannot use string offset as an array in /home/www/cms/typo3_src-4.0/t3lib/class.t3lib_tcemain.php on line 1950"

Just get's skipped - the database get's filled with the appropriate values afterwards and the error won't
occur again.

Create a simple flexform with a section. Add an section-element to a section empty before. Don't fill
in any values but just press "Save". It will only fail in PHP5

Quite obvious. See the attached patch.
