bb.utils: remove old portage remnants

The following utility functions were removed.  Note that in this particular
case we're bypassing a proper deprecation process, as these functions are
clearly not utilized, are obvious remnants of old ways of doing things, and
some of which do not even function properly.

- tokenize
- evaluate
- flatten
- relparse

- ververify
- isjustname
- isspecific
- catpkgsplit
- pkgsplit
- pkgcmp
- dep_parenreduce
- dep_opconvert
