Turns out, nothing should be changed in our implementation because
nil-check is done implicitly by type casts or type switches.

`storage.Seek()` is rather expensive and we need only last updated value
of gas per block in `PostPersist()`.

Problem: with StateRootInHeader setting on only one header of height N+1
can be added to the chain of height N, because we need local stateroot
to verify headers (which is calculated for the last stored block N).
Thus, adding chunk of headers starting from the current chain's heigh
is impossible and (*Blockchain).AddHeaders doesn't have much sense.
Solution: verify header.PrevStateRoot only for header N+1. Rest of the
headers should be added without PrevStateRoot verification.
For `nft-nd-nns` example only `namestate.go` file was compiled which is
certainly not what we want.

If a method is known at compile time we can still check
if it is present in the list of methods of at least one contract.

On many occassions we can determine at compile-time if contract config lacks
some properties it needs. This includes all native contract invocations
through stdlib, as both hashes and methods are known at compile-time
there.

(*NEO).GetCandidates along with getCandidatesCall use candidates sorted
by serialized ECPoint bytes.
(*NEO).computeCommitteeMembers use candidates sorted by votes, and then
by deserialized ECPoint, i.e. using default ECPoint comparator.
Update neofs-api-go to `v1.27.1`.
Add `WithURIAddress` client option.
Stop using `V2` abstractions outside
of the `api-go` library.

This is not a problem in practice, as all keys are prefixed
by a contract ID. However in theory it can lead to a different
state root after new portion of changes thus this fix.
This has the drawback of traversing expression each time the argument is
used. However this is not the case in our syscall/native wrappers.
The old behaviour can be restored by explicit local assignment.
