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
This is a follow-up commit to "Increase default warning level", which
overrides Genode's new default warning level for targets contained in
higher-level repositories. By explicitly whitelisting all those targets,
we can selectively adjust them to the new strictness over time - by
looking out for 'CC_CXX_WARN_STRICT' in the target description files.
Issue #465
