L4Re::Util::Dataspace_svr

[Daniel Müller]

Hello,

L4Re::Util::Dataspace_svr's copy functionality is not very flexible. It 
only works for local dataspaces which I believe is insufficient.

The problem is the "if (!src_cap.id_received())" construct in the 
L4Re::Dataspace_::Copy case in the dispatch method. Imo this should be 
something comparable to the validate_ds() method used in region_mapping_svr.
