This function was very obfuscated. I hope the newer version is more
clear, but IMHO it keeps being bad because:
- Its name is confusing because it checks both the graveyard and the
garbage.
- It has no interface. We use that function in several metabase methods,
it just returns some 'magic' uint8 numbers and has no doc comment, I
mean it's ridiculous.
- It checks out for 'the node being in incorrect state' for some reason
but that result isn't used further. I kept a comment about that but it
has no logic for me.

`fmt.Errorf can be replaced with errors.New` and `fmt.Sprintf can be replaced with string addition`

Most of the time it exits, e.g. when it is per-container and use on each
object PUT. Bbolt implementation first tries to create bucket and then
returns it if it exists. Create operation uses cursor and thus is not
very lightweight, we can avoid it.

- Meta now supports (and requires) inc/dec labeled counters
- The new logic counter is incremented on `Put` operations and is
decremented on `Inhume` and `Delete` operations that are performed on
_stored_ objects only
- Allow force counters sync. "Force" mode should be used on metabase resync
and should not be used on a regular meta start
