6280d075b9 [#208] Remove childfree search attribute
With updated specification of object related operation
we don't have this search attribute any more and we
should not use functions related to this attribute.

This commit breaks object service logic, however it will
be fixed later.

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.

fcb35d82cf [#165] Revert "[#142] metabase: Store header value index in a tree leaf"
Revert commit 0faa40e4 to increase the disk space consumed by the
metabase in favor of the speed of index updates.

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).
