core: move new object system to core module

this will allow a wider range of data structures (e.g. b_error, b_stream, b_stringstream) to make use
of the new object system, and other modules and library users can use the object system without
depending on the blue-object or blue-ds modules.

blue-ds will become a simple library of data structures (string, hashmap, etc), built on top of the
core object system.
