Before this CL, some components, e.g. the SendQueue, was first created
and then later restored from handover state, while some were created from
the handover state, as an optional parameter to their constructors.
This CL will make it consistent, by always creating the components in a
pristine state, and then modifying it when restoring them from handover
state. The name "RestoreFromState" was used to be consistent with SendQueue
and the socket.
This is just refactoring.

When a FORWARD-TSN is received as the first chunk on an ordered stream,
it will fail to set the new "next expected SSN" that is present in the
FORWARD-TSN as that stream hasn't been allocated yet. It's allocated
when the first DATA is received on that stream.
This is a non-issue for ordinary data channels as the first message on
any stream will be the "Data Channel Establishment Protocol" messages,
which are always sent reliably. But if prenegotiated channels are used,
and the very first packet received on an ordered data channel is lost
_and_ signaled to the receiver as lost _before_ the receiver has
received any other fragments on that data channel, future messages will
not be delivered on that channel.

dcSCTP library users can set their custom
g_handover_state_transformer_for_test that can serialize and
deserialize the state. All dcSCTP handover tests call
g_handover_state_transformer_for_test. If some part of the state is
serialized incorrectly or is forgotten, high chance that it will
fail the tests.

This class handles the assembly of fragmented received messages (as DATA
chunks) and manage per-stream queues. This class only handles
non-interleaved messages as described in RFC4960, and is not used when
message interleaving is enabled on the association, as described in
RFC8260.
This is also only part of the reassembly - a follow-up change will add
the ReassemblyQueue that handle the other part as well. And an even
further follow-up change will add a "interleaved reassembly stream".
