DevMgr: Rename at/detachAll*Req():

We've renamed these now to better reflect what they do.
* attachAllSenseDevicesFromSpecsReq=>attachAllUnattachedDevicesFromReq
* detachAllSenseDevicesReq=>detachAllAttachedDeviceRoles

This is also the first step in changing
attachAllUnattachedDevicesFrom to accept a sh_ptr<> to a collection
of DeviceAttachmentSpecs. This will enable us to unify the underlying
spec attachment logic and just create several front-ends for attaching
specs from multiple sources.
