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
