If the container ID is not nil and not equal to the container ID in the
request, consider bearer token invalid.

After recent changes in NeoFS SDK Go library session tokens aren't
embedded into `container.Container` and `eacl.Table` structures.
Group value, session token and signature in a structure for container
and eACL.

Core changes:
* avoid package-colliding variable naming
* avoid using pointers to IDs where unnecessary
* avoid using `idSDK` import alias pattern
* use `EncodeToString` for protocol string calculation and `String` for
printing

Not all the NeoFS requests must contain OID in their bodies (or must NOT
contain them at all). Do not pass object address in helper functions, pass
CID and OID separately instead.
Also, fixed NPE in the ACL service: updated SDK library brought errors
when working with `Put` and `Search` requests without OID fields.

Parse all headers beforehand and reject invalid requests.
Another approach would be to remember the error and check
it after `CalculateAction`, which is a bit faster.
The rule of thumb here is "first validate, then use".

Make all operations that related to `neofs-api-go` library be placed in `v2`
packages. They parse all v2-versioned structs info `neofs-sdk-go`
abstractions and pass them to the corresponding `acl`/`eacl` packages. `v2`
packages are the only packages that do import `neofs-api-go` library. `eacl`
and `acl` provide public functions that only accepts `sdk` structures.

In previous implementation node returns "access denied" on Object.Put with
object with unset owner. Although object owner must be set, its absence
should not be considered as access error. The same applies to sender key.
Check owner ID and public key emptiness only if sticky bit is set.

Session token can be present in both object header and
request meta header. They are the same during initial object
placement.
At the object replication, storage node puts object without
any session tokens attached to the request. If container's eACL
denies object.Put for USER role (use bearer to upload), then
replication might fail on objects with session tokens of the
signed by container owner. It is incorrect, so use session
token directly from request meta header.

In previous implementation sticky bit could disrupt access of container
nodes to replication. According to NeoFS specification sticky bit should not
affect the requests sent by nodes from SYSTEM group.
Add role check to `stickyBitCheck`.

As it explained in previous commit, session token also should
be presented in original meta header but can be omitted in higher
layers.

Request meta headers are organized in a layers, where
upper layers re-sign down layers. Bearer token should be
a part of original meta header and it can be omitted in
upper layers. Therefore we need to traverse over linked list
of meta header to the original meta header to get bearer token.

In previous implementation of eACL service v2 the response X-headers were
validated at the stage of re-checking eACL. This provoked a mismatch of
records in the eACL table with requests. Fix this behavior by checking the
headers from the request, not the response.

Sticky bit checks if object owner and request owner are the
same. Container owner should not used in this check.

`owner` field may be misused as request sender owner, however
it is a owner of a container for that request. New naming
should be clear.
