migrate Podman to containers/common/libimage

Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.

Note that I tried to leave bread crumbs for changed tests.

Miscellaneous changes:

 * Some errors yield different messages which required to alter some
   tests.

 * I fixed some pre-existing issues in the code.  Others were marked as
   `//TODO`s to prevent the PR from exploding.

 * The `NamesHistory` of an image is returned as is from the storage.
   Previously, we did some filtering which I think is undesirable.
   Instead we should return the data as stored in the storage.

 * Touched handlers use the ABI interfaces where possible.

 * Local image resolution: previously Podman would match "foo" on
   "myfoo".  This behaviour has been changed and Podman will now
   only match on repository boundaries such that "foo" would match
   "my/foo" but not "myfoo".  I consider the old behaviour to be a
   bug, at the very least an exotic corner case.

 * Futhermore, "foo:none" does *not* resolve to a local image "foo"
   without tag anymore.  It's a hill I am (almost) willing to die on.

 * `image prune` prints the IDs of pruned images.  Previously, in some
   cases, the names were printed instead.  The API clearly states ID,
   so we should stick to it.

 * Compat endpoint image removal with _force_ deletes the entire not
   only the specified tag.
