DAP.yy: use cmdlineDASpecs; DevMgr: add attachAllUnattachedDevicesFromCmdlineReq

This method wraps around attachAllUnattachedDevicesFromReq and supplies
it with a sh_ptr<> collection of all DASpecs parsed by the DAP parser
from the cmdline.

The initialization sequence now correctly initializes all DAP specs
given on the cmdline again.
