Roman Khimov c2b3ee3d8e core: move basic chain creation into a package of its own
This allows to reuse it across different packages.

testchain can't be used because of circular dependencies.

Init() is not changed except for filepath.Join() use instead of direct string
appends which is a better approach anyway. rootpath is required because
current directory will change from package to package.
