to the object. Pass session token from trusted object Put.

Basic ACL checker gets request field via getters that are
NPE-free, therefore we don't need to worry about function
invocations on nil structures.

ACL has to classify request senders by roles:
- owner of the container,
- request from container or inner ring node,
- any other request.
According to this roles ACL checker use different
bits of basic ACL to grant or deny access.

In previous implementation payload size limiter panicked in case of payload
emptiness. It was caused by the component waiting for at least one write of
a part of the payload.
Fix NPE occurrence with internal initialization after the WriteHeader call.

with provided object payload range.

In previous implementation one excess element could be added to the chain.
Add previous sibling presence check to prevent this.

Add FullRange option to get range operation parameters that allows to get
payload range [0:object_size] w/o the actual knowledge of the object size.

Head service receives right child of the processing object in some cases.
Add right child to Head result in order to use it as needed.

Large inner ring requires more gas to make container registration.
Container contract makes balance transfers for each inner ring node
and it require extra gas to execute. This estimation should be enough
for seven inner ring nodes.
Later there should be heuristic evaluations for this: #47

In previous implementations object size limiter left checksums of parent
object payload unset. This was caused by the closure that written calculated
checksums to the child object instead of parent one.
Construct payload checksum writers in separate function in order to prevent
closure bug.

Container get wrapper implements container.Source interface
so it can be used in object service as container storage.

Default values for capacity and price will be 0, so storage node
won't be present in placement. Add these attributes if they are
not explicitly set up by user config.

Well-known attributes set up with explicit configuration
values, other attributes set up from chain of attributes.
Chain of attributes is a string, that contains keys-value pairs,
divided by semicolon. Pairs itself divided by slash.
E.g. "StorageType:HDD/RPM:7200"
