Add `TypeLock` value to `Type` enum. Implement `Lock` type compatible
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.

In previous implementation `Close` method of `ObjectReader` /
`ObjectRangeReader` could incorrectly return `io.ErrUnexpectedEOF` of
payload wasn't read by `Read` method (in this case
`remainingPayloadLen` state var is not updated).
Return `io.ErrUnexpectedEOF` from `Read` method only.

In previous implementation all `Read` methods read single response
per-call, so buffer could be incompletely filled w/o an error. In order
to follow `io.Reader` docs we need to continue filling the buffer while
it is possible.

In previous implementation `ObjectListReader.Read` returned `false` on
server responded with empty ID list. This could cause premature end of
reading since the protocol does not forbid intermediate empty lists.
Do not stop if ID list from response body is empty.

In previous implementation payload chunks were split into pieces with
512B length. This led to sending a large number of messages with a large
amount of payload.
Increase per-message payload chunk limit to 3MB.

We should provide the ability to customize private of object HEAD /
DELETE ops.
Implement `UseKey` method on `PrmObjectHead` / `PrmObjectDelete` types.
Sign requests with the specified key if called.

Add helper function which accepts container and object identifiers and
returns object instance read to the memory.

From now session token for `SetEACL` operation should be written into
eACL table structure (similar to `PutContainer`).

Make `ObjectReader` / `ObjectRangeReader` to track number of bytes read
and return:
* `io.ErrUnexpectedEOF` if the stream finished by the server before
the last byte of the payload was read.
* an error if more object payload size bytes was read.

PutContainer method takes `container.Container` structure
as an argument. This structure already contains session
token field, so there is no need in `prmSession` because it
duplicates session token definition.

Define `XPrm` type for each `X` client operation which structures
parameters. Export setters of each parameterized value. Emphasize that
some parameters are required. Make the client panic when the parameters
are incorrectly set. Get rid of vadiadic call options and `CallOption`
type. Improve documentation of client behavior.

In the latest NeoFS protocol update, each request is provided with a
network magic number. We have to provide the ability to set it on
the client.
Add `WithNetworkMagic` option constructor which accepts magic number.
Write the number to meta header of the all requests.

This option make client parse all NeoFS error statuses and return them as
errors from method calls (not as part of result structure). This is done
for applications that want to handle errors as it is customary in golang.
Default behaviour (construction client without new option) has not been
changed.

Make all `Client` methods to return structured values and error. Parse v2
status messages in all RPC and provide status getter from all result
structures. Returns status failures as status result instead of error.
Interface changes:
* all methods return `<method>Res` structure;
* rename some methods to be more clear;
* unify TZ and SHA256 objecy payload hashing in single method.
Behavior changes:
* client doesn't verify object header structure received via Object.Head.
If the caller was tied to verification, now it must do it explicitly.
