This patch makes sync work with syncml-ds-tool

Fixed SyncML initialization to create a single session on sync
initiation from the syncml-ds-tool. Tested that the sync succeeds from
the output of the contact on the PC. The QDeviceInfo class has a problem
that the QDeviceInfo::imeiCount() crashes. Hardcoded a dummy IMEI number
for the time being. There is still a problem that
QSocketNotifier::activated gets triggered at every instance. Probably
glib IO functions have to be used. Next steps: mFd gets closed after one
sync session. Also, sync results need to be handled properly
