* Separated iteration through container ids from `ContainersOf()`
so that it could be reused.
* When listing containers we used to iterate through the
the whole list of containers twice: first when reading from
a contract, then when sending them. Now we can send batches
of containers when reading from the contract.

ContainersOf() is better in almost every aspect, besides creating a
session when the containers number is between 1024 and 2048 (prefetch
script does limited unwrapping). Making List() private helps to ensure
it is no longer used and can be safely removed in future.

Besides VM stack item limit we also have restrictions on the size of
JSON for a stackitem, which is 128k. This limit is much harder to
calculate, because JSON representation includes type and the encoding is
different for different items. Thus is makes no sense to invent our own
default, so use the one provided by neo-go. But for container listing we
know exactly what we process, so use big enough value, which is tested.

When the number of items to iterate over is less than 2048, there is no
need to create a session and consume resources.
