Connection pool package should not define `Pool` type as an interface
since it provides single particular implementation.
Make `pool.Pool` type a struct instead of interface. Also remove
`Object`, `Container` and `Accounting` interfaces.

Some callbacks, such as `close()` -> `result(v2)` may
generate new errors, so `processCall` should not ignore
them.

`SignData`: use `ECDSAWithSHA512` by default. `SignWithRFC6979` option
switches the scheme to `RFC6979WithSHA256`.
`VerifyData`: if scheme is not fixed (like by `SignWithRFC6979` option)
then scheme from the message is processed.

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 we wrote up to 4KB payload chunk per-call.
This led to sending a large number of messages with a large
amount of payload.
Increase buffer length limit to 3MB.
