Capacity field is obsolete and removed. Salt field renamed to
Nonce so it shows better the purpose of the field.
Remaining fields are reorded to have fixed size fields on top.
It affects stable-marshaller implementation.

With new ACL conception, access control lists in NeoFS
defined as a required basic ACL and optional extended ACL.
Basic ACL must be set up in container structure. It is a bit
mask stored in 32-bit unsigned integer.
Seven nibbles represent seven object operations: get, put,
head, search, delete, range, range-hash.
Every nibble defines access rules for three targets: user,
owner, others and has permission bit for bearer token.
There is a permission bit for extended ACL and three unused
bits.
