fdeea1dfac [#2057] meta: Fix concurrent mode changes
Includes:
1. mode change read lock operation in every exported method that r/w the
underlying database;
2. returning `ErrDegradedMode` logical error if any exported method is
called in degraded (without a metabase) mode.

From the `Bucket.ForEach` doc:
```
The provided function must not modify the bucket; this will result in undefined behavior.

ad47e2a985 [#1658] meta: Add logic counter
- 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

6f243a2a76 [#1483] metabase: Store version
The main problem is to distinguish the case of initial initialization
and update from version 0. We can't do this at `Open`, because of
`resync_metabase` flag. Thus, the following approach was taken:
1. During `Open` check whether the metabase was initialized.
2. Check for the version in `Init` or write the new one if the metabase
   is new.
3. Update version in `Reset`.

8107c8d1a9 [#1318] metabase: Separate buckets with TS and GC marks
It allows storing information about object in both ways at the same time:
1. Metabase should know if an object is covered by a tombstone (that is
not expired yet);
2. It should be possible to physically delete objects covered by a
tombstone immediately (mark with GC) but keep tombstone knowledge.

55c94a0152 [#789] metabase: Implement Reset method
In the previous implementation of the metabase, there was no possibility of
reinitializing the metabase: clearing information about existing objects and
bringing it back to its initial state. This operation can be useful in
cases when the stored metadata about objects has lost (or possibly lost)
relevance, and you need to generate data from scratch. Also at the
initialization stage, static resources of the base were not created -
container-independent buckets.

Make `Metabase.Init` method to allocate graveyard, container-size and
to-move-it buckets in underlying BoltDB instance. Implement `Metabase.Reset`
method: it works like `Init` but clean up all static buckets and removes
other ones. Due to the logical similarity, the methods share a single piece
of code.
