* SQL based state management. Responsible for maintaining device state

*
* Needs a number of SQL tables present:
* syncStateTable (horde_activesync_state):
* sync_timestamp: - The timestamp of last sync
* sync_key: - The syncKey for the last sync
* sync_pending: - If the last sync resulted in a MOREAVAILABLE, this
* contains a list of UIDs that still need to be sent to
* the client.
* sync_data: - Any state data that we need to track for the specific
* syncKey. Data such as current folder list on the client
* (for a FOLDERSYNC) and IMAP email UIDs (for Email
* collections during a SYNC).
* sync_devid: - The device id.
* sync_folderid:- The folder id for this sync.
* sync_user: - The user for this synckey.
* sync_mod: - The last modification stamp.
*
* syncMapTable (horde_activesync_map):
* message_uid - The server uid for the object
* sync_modtime - The time the change was received from the PIM and
* applied to the server data store.
* sync_key - The syncKey that was current at the time the change
* was received.
* sync_devid - The device id this change was done on.
* sync_user - The user that initiated the change.
*
* syncDeviceTable (horde_activesync_device):
* device_id - The unique id for this device
* device_type - The device type the PIM identifies itself with
* device_agent - The user agent string sent by the device
* device_policykey - The current policykey for this device
* device_rwstatus - The current remote wipe status for this device
*
* syncUsersTable (horde_activesync_device_users):
* device_user - A username attached to the device
* device_id - The device id
* device_policykey - The provisioned policykey for this device/user
* combination.
