Fix the synml fragmentation support problem detected on some phones
such as the Nokia E61.
This affected most phones/devices that use SyncML with the vcard/vcalendar
format.
Fix from Christoph Kaulich, thanks.
- 24518: prevent deleting of accounts via SyncML and to read private flag from the DB if missing
- 24531: Merge SyncML patches from Patrick Bihan-Faou plus some other SyncML fixes from trunk
- 24555: fixed bug introduced by my commit r24522 (included in 24531): egw could not deal with LDAP Ids
- 24571: fixed typo reported by Thomas Hoth on the developer list, causing calendar sync in trunk to fail if the clients wants categories
