Actually the examples directory has been used as a staging for ethtool and
lthread. We also have the crypto API which is still experimental.
So I think we must decide among these 3 solutions:
	- no special directory, just mark and document an experimental state
	- put only kcp/kdp in the staging directory
	- put kcp/kdp in staging and move other experimental libs here
