f2e5dead7e [#398] pilorama: Disallow applying same operations 
1. In redo() we save the old state.
2. If we do redo() for the same operation twice, the old state will be
   overritten with the new one.
3. This in turn affects undo() and subsequent isAncestor() check.

1f4061c0e2 [#285] blobonicza: Optimize upperPowerOfTwo() 
The real reason is this:
```
pkg/local_object_storage/blobovnicza/sizes.go:36:69
    revive empty-block: this block is empty, you can remove it
```

Didn't want to make this function longer or to add `nolint`, thus this
change. To justify:

e9461686b8 [#274] wc: Resolve possible deadlock 
If operation with WC are _fast enough_ (e.g. `Init` failed and `Close` is
called immediately) there is a race and a deadlock that do not allow finish
(and start, in fact) an initialization routine because of taken `modeMtx`
and also do not allow finish `Close` call because of awaiting initialization
finish. So do stop initialization _before_ any mutex is taken.
