Now alphabet contracts use signature collection to make
a vote. All inner ring nodes votes for some list of validators
the same way as they vote fore new epoch or new container.
As soon as list is accepted by alphabet contracts, each of them
votes for one candidate from the list.

In previous implementation placement traverser processed incorrectly with
local placement build. Also entity incorrectly traversed the placement
vectors for fixed number read operations until success. The erroneous

ErrEACLNotFound error was defined in implementation package. EACL validator

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.

Revert commit 0faa40e4 to increase the disk space consumed by the
metabase in favor of the speed of index updates.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
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.

a mismatch in the previous filter.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
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).

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).
