SPM: Implementation error codes update

Even SPM care only about the error code returned from implementation
functions is successful or not, the returned error code still can be
logged somewhere for debug/logging purpose. 'bool' is not a good
candidate for the return type, in case the implementation has rich
internal error codes.

Create an implementation error code base, and implementation could
expand its own error codes base on this base.
