Field with object revision number was introduced for the future, however, at
the moment it is not used anywhere. This commit removes field Version from
SystemHeader message. It can be added back later without losing API
backward compatibility.

In previous version of the format ExtendedHeader consisted of one field
Value, defined by oneof mechanism. Such a definition format give complete
freedom when composing an object header, however, it did not allow strictly
structuring the header format at the level of type syntax. Since the object
has a well-defined structure in the system, this commit replaces the
definition through oneof with a set of fields. As a consequence, storing a
set of extended headers of the new type in the general header became
redundant, so the repeated keyword was removed.

This commit replaces Transform message with SplitHeader in oneof definition
of Value field of Header message. The latter, unlike the first, carries
complete information about the generation of the object by splitting the
payload. As a result, the message is deleted as no longer used.

This commit defines SplitHeader message that encapsulates data about
spawning the object through a payload splitting. Message fields contain
information about the hierarchy in the split-chain as well as information
about the origin object.

This commit merges object system header fields ID and CID into field Address
of type refs.Address. This will allow you to reuse an already existing type
of object reference without duplication and simplify taking the address
from the object body

In previous version of the format Object message included moment of creation
in two epoch times: NeoFS and Unix. Since unix is not processed in the
system, this commit narrows the time point of object creation to the system
epoch number. The object.CreationPoint message has therefore been deleted
as no longer used

In previous version of the format Object message included two header fields:
SystemHeader and list of ExtendedHeader. Due to the fact that all headers
were not encapsulated in a single message, some messages were forced to use
Object to convey the full header of the object (e.g. object.HeadResponse).
To resolve this semantic inconsistency, this commit defines a Header
message, consisting of a system and an extended portion. As a result, the
Object now consists of two fields - Header and Payload.

The naming Header obscures its semantic meaning precisely as a subclass of
the general object header. To clarify the layers of typing object headers,
this commit renames the message to ExtendedHeader. As a result, the Headers
field in the Object has been renamed to ExtendedHeaders.

The name of object.UserHeader message implies its use by the user. However,
the attributes of an object can also be set internally by the system. To
generalize the intended purpose of the message, this commit renames it to an
Attribute (like container.Attribute).

This commit replaces Range message definition closer to where it is used. In
the future, only the types associated with the structure of the object will
be defined in types.proto file.
