The CBE repository contained a lot of Genode-specific code despite the fact that the CBE core logic is not bound to Genode in any way. Therefore the Genode-specific CBE code is moved to the 'gems' repository to form part of Genode mainline. The remaining CBE code becomes a port in Genode instead of being invoked as sub-repository. The commit combines the following work steps: * add all files removed from CBE repository * add CBE port files * make all CBE libs and targets build again * make all CBE run scripts succeed again * make all CBE recipes build again * make CBE autopilot succeed again * let CBE autopilot use 'libsparcrypto' contrib dir and Genode build dir instead of '.ci' dir in CBE contrib dir (remove '.ci' dir from CBE repo) * let CBE autopilot always check for all ports * make CBE autopilot directly executable * fix license headers in all Genode CBE files * remove unused VFS replay component * remove unused CBE test * remove unused external crypto * remove unused files in run dir * remove unused external trust anchor * add cbe_tester test to autopilot list * get rid of directories 'include/cbe_*' and 'include/utils' Fixes #3937
