4da41613c3 [#378] shard: Initialize GC processes on Init
`Shard.Init` method creates a new GC instance from shard configuration and
starts GC's workers through `init` call. In initial implementation GC
routines are indefinite and can be killed only with by application shutdown.

13087dc3dd [#378] shard: Implement skeleton of internal GC
Shard's GC component consists of:
 * asynchronous remover that periodically wake up and removes all garbage
   objects from the shard, and goes to sleep for particular time interval;
 * external event listener that distributes jobs between workers;
 * group of workers that can handle a single job related to particular
   external event.

Remover and event listener represents go-routines which are started by
`init` method (calls from `Shard.Init`). In initial version all event
handlers are interrupted: this means that next event of the same type will
interrupt previous handling and start the new one.

GC is fully encapsulated in Shard. All GC configurations are reflected in
Shard's configuration.

7c3f828893 [#219] metabase: Count parent references in Delete operation
Delete operation of Metabase is performed on group of objects. The set being
removed can contain descendants of a common parent. In the case when all
descendants of a parent object are deleted, it must also be deleted from
the metabase. In the previous implementation, this was not done due to the
chosen approach to counting references to the parent.

a2c2241356 [#379] storage engine: Inhume object in one shard
In previous implementation StorageEngine.Inhume operation forced Shard
.Inhume call on all internal shards. There is a need to inhume object in a
single shard. To achieve this, Inhume operation is performed in next steps:

 1. iterate over sorted shards, check object presence through Exists call;
 2. if object exists at any shard in step 1 => inhume it and return on
    success;
 3. if no shards contain the object => iterate over sorted shards again and
    try to inhume the object at first possible shard;
 4. if all Inhume calls are failed => return an error.

e6f2d84736 [#246] blobovnivza: Fix deadlock on concurrent evict and open new blobovnicza
Deadlock occurs when `getActivate` function opens new blobovnicza and that
invokes evict in LRU cache of open blobovniczas. `getActivate` makes
`activeMtx.Lock()` and then cache evict makes `activeMtx.RLock()` and deadlock
happens.

Fix contains two steps:
- add separate mutex to open blobovniczas (1),
- split single Lock outside of `updateAndGet` (2).

As for the (1) `bbolt.Open()` locks when it tries to open the same file from
two threads. So separate mutex will prevent that.

As for the (2) `updateAndGet` function contains from two parts. At first it
checks if required blobovnicza is ready and it returns it. In this case we can
use the simple RLock. But then there is an option when we should open new
blobovnicza and update map of active blobovniczas.

In this case we call `openBlobovnicza` without activeMtx lock. Cache evict
happens there and it won't cause deadlock.

Then we lock activeMtx to update the map of active blobovniczas. Concurrency can
happen there. However `openBlobovnicza` will not open the same blobovnicza twice,
so we can make one more check if opened blobovnicza was activated while thread was
locked in activeMtx. If so, then return active blobovnicza, else finish activation.

91bea44a1a [#245] blobovnicza: Fix initializing dimensional buckets
In previous implementation Blobovnicza could incorrectly initialize
dimensional buckets: if SmallSizeLimit = 2 ^ X + Y && Y < 2 ^ X, then
largest dimensional bucket was [2 ^ (X - 1) : 2 ^ X]. This was caused by an
incorrect condition for stopping the iterator along the dimensional
boundaries.

eaae5a5dd7 [#229] blobovnicza: Store objects in a binary format
In previous implementation Blobovnicza's stored objects in protocol format
which did not allow working with externally compressed objects. To achieve
this goal, operations Get and Put no longer work with the structure of the
object, but only with abstract binary data. Operation GetRange has become
incorrect in its original purpose to receive the payload range. In this
regard, BlobStor receives the payload range of the object through Get
operation. In the future either Blobovnicza will learn to compress objects
by itself, or the GetRange operation will be eliminated.

There is a need to support single blobovnicza in blobovnicza tree. This can
be achieved with a width of 1, and a depth of 0 or 1. With depth = 1 one
redundant directory is created, inside which there is a blobovnicza. If the
depth is zero, the blobobnivza will be in the root path. Fix negative

With the transition to static weights of shards, it is no longer

However, since the set of engine shards is dynamic, there is still a
need to control multiple access to this set. The same mutex is used

03fed8ca59 [#160] Update metabase with new root and phy flags processing
Now root and phy (leaf) filters work like flags. They work with
any matcher and any value. So meta-storage sets `true` value for
all root and phy objects and puts them into separate bucket.

We also do not work with inversion anymore, so it either added
to the bucket or not. We don't need to store both options.
This is the reason `selectAll` function is changed a bit. Now
it performs some low-level parsing from primary bucket and root
bucket.

200fdbd361 [#149] metabase: Do not write virtual objects to the primary index
In the previous implementation of the metabase, it was necessary to write
virtual objects to the primary index to be able to select them. In this
approach, virtual objects can be obtained directly using Head operation.
This has a side effect in handling object operations that do not expect to
receive a virtual object header in a single operation. With recent changes,
it is no longer necessary to have records of virtual objects in the primary
index, so this no longer happens for system integrity.

77e80f517f [#142] metabase: Store header value index in a tree leaf
In the previous implementation of the metabase, the unique value of the
header was assigned a bucket, the elements of which were leaves with a
key-address and an empty value. This approach was relatively efficient in
terms of write speed. However, a large number of buckets led to a rapid
increase in the database volume (~4GB for 100K objects with unique
attributes). An approach is presented with storing indexes on the value of
headers in the leaves of the tree, where the keys are the unique values ​​of
the header, and the values ​​are a serialized list of addresses (gob
encoding is temporarily used for serialization).

The new approach gave a good result in saving space (~350MB), however, it
significantly reduced the write speed with an increase in the number of
objects (~ 80x after 100K objects).

e48f8a189e [#142] metabase: Replace exclusive select with the inclusive one
The previous metabase implementation took an exclusionary approach: filters
narrowed the set of all objects to those that match all filters. An
inclusive approach is presented. In it, when traversing the indexed headers,
the object becomes a candidate for selection. If at least one of the
subsequent filters is not passed, the object ceases to be a candidate. At
the end of the traversal, the remaining candidates are added to the
resulting sample. The borderline case of no filters is handled in a special
way: all stored objects are added to the resulting selection.

Presented inclusive approach showed better performance in most scenarios
(although not all).
