Sequence numbers are now used to match requests with replies.
Mock adapter thus has to be able to tell how many messages
from the head of the queue with mock replies belong to the currently
processed request. Then they can be given the right context and
the rest of the queued replies are postponed to be delivered later
(when context of their request is known).
All replies for one request are now therefore queued together.
This affects just multipart requests for which replies have to
be pushed all at once. The trailling control ping reply is still
queued separately, however, because that is actualy another request,
e.g.:
mockVpp.MockReply( // push multipart messages all at once
&interfaces.SwInterfaceDetails{SwIfIndex:1},
&interfaces.SwInterfaceDetails{SwIfIndex:2},
&interfaces.SwInterfaceDetails{SwIfIndex:3},
)
mockVpp.MockReply(&vpe.ControlPingReply{})
Even if the multipart request has no replies, MockReply has to be
called exactly twice:
mockVpp.MockReply() // zero multipart messages
mockVpp.MockReply(&vpe.ControlPingReply{})

Requests are given sequence numbers (cycling over a finite set of 2^16
integers) that are stored into the lower 16bits of the context.
1bit is also allocated for isMultipart boolean flag and the remaining
15bits are used to store the channel ID. The sequence numbers allow
to reliably pair replies with requests, even in scenarious with timeouted
requests or ignored (unread) replies.
Sequencing is not used with asynchronous messaging as it is implemented
by methods of the Channel structure, i.e. above ReqChan and ReplyChan
channels.
