Namesys is a very useful submodule. Given a ValueStore and a Datastore it can resolve and publish /ipns/ paths. This functionality does not need to be sequestered inside go-ipfs as it can and should be used without IPFS, for example, for implementing lightweight IPNS publishing services or for resolving /ipns/ paths. "keystore" extraction was necessary, as there is a dependency to it in namesys. Keystore is also a useful module by itself within the stack. Fixes #6537
