The expiration epoch is the _last_ valid epoch for an entity. Also, clarify
the expiration epoch meaning for tombstones and regular objects.

field.

implementation into conformity with the NeoFS API protocol.

Remove `signature` and `util/signature` packages. Re-implement their
functionality in new `crypto` package. Generalize the approach of
digital signature computation and verification by adding `Signer` and
`PublicKey` primitives similar to standard `crypto` package. Support
already exising in protocol signature schemes.

with corresponding message. Implement `ObjectLocked` and
`IrregularObjectLock` errors in `apistatus` package.

Allow `SignOption` to set 2 parameters:
1. Default signature scheme, which is used in case scheme is
unspecified.
2. Restrict scheme option which also checks that scheme is either
unspecified or equal to the restricted scheme. This is only used
for verification and is necessary because some of the signatures
are used in smart-contracts.
Also provide signature struct to sign/verify functions in helpers.
The constant names differ a bit from those in API because of linter
complaints.

This is done to prevent import cycles when `object` package needs any other
that requires `object.ID` or `object.Address`.
