d52e9f35bc ackhandler: detect ECN mangling (#4080) 
* ackhandler: detect ECN mangling

Mangling means that a path is re-marking all ECN-marked packets as CE.

* ackhandler: only detect ECN mangling once all testing packets were sent

8f3a68b4eb ackhandler: use a slice to keep track of sent packets (#3841) 
* ackhandler: simplify deletion of old packets in packet history

* ackhandler: use a slice to keep track of sent packets

This is a vastly simpler data structure than the combination of map
and linked list used before. It avoids using a linked list (bad cache
locality) and a sync.Pool (for list elements), as well as having to do
hash table lookups.

In the future, this can be easily replaces with a ring buffer, avoiding
all allocations.

* ackhandler: don't store packets that were declared lost

Marten Seemann
d9665c632e use a sync.Pool to reduce allocation of linked list elements 
Especially the sentPacketHistory linked list shows up in allocation
profiles, since a new list element is allocated for every single packet
we send.
Using a pool for the receiving path, as well as for the frame sorter, is
less critical, since we're tracking ranges there instead of individual
packets / frames, but it doesn't hurt either.
The other occurrences where we use a linked list (connection ID tracking
and the token store) are used so rarely (a few times over the lifetime
of the connection) that using a pool doesn't make any sense there.
