app-eselect/eselect-wine: add 2.0.0, unkeyworded for testing

Complete rewrite but for notable bits:
- removes register/deregister, can auto-update without this
- no longer touch files in /usr at runtime wrt bug #632576, in this
  case it was particularly invasive doing *many* modifications to
  /usr/bin and /usr/share/man
- handle /usr/lib/wine fwiw wrt bug #657748 (installed by the
  ebuild), albeit winebuild can find the right path nowadays
- fix prefix wrt bug #717470
- give feedback when switching wrt bug #874612
- tries harder to not unexpectedly switch variant/version, and
  no longer need ebuild checks wrt bug #881035
- no longer hardcodes variants and so can support any random ones,
  i.e. an overlay can do wine-tkg or wine-myfunnyfork
- --all, --vanilla, etc.. options were removed, but can still
  perform similar actions (see `help`)
- `list` can now show selections for all variants at once
- `unset` removed, not seeing a motivation (esp if not polluting /usr)
- half+ the original size, and switches variant noticeably faster

Still experimental and subject to changes, so unkeyworded for now.
See README.rst for more notes, or the tarball's impl.rst for details.

ebuild itself needs some nonsense largely caused by being difficult
to get rid of the old eselect plus portage limitations.
