* make it possible to pack path probes with multiple frames
* simplify function signature of pathManager.HandlePacket
* simplify connection short header packet handling logic
No functional change expected.
* make server send PATH_RESPONSEs on the same path
This makes sure that we’re actually testing for return routability.

A reordered PATH_CHALLENGE (or one sent on a slower path)
should still trigger a PATH_RESPONSE. The RFC only forbids
switching the path unless the non-probing packet has the
highest packet number received so far.

When receiving a ClientHello for a 0-RTT connection, this allows us to derive both 0-RTT and Handshake keys at the same time. The previous logic used to inadvertently discard previously undecryptable packets (e.g. reordered 0-RTT packets).

* remove unused bool return value from sentPacketHandler.getPTOTimeAndSpace
* ackhandler: implement timer logic for path probing packets
Path probe packets are treated differently from regular packets: The new
path might have a vastly different RTT than the original path.
Path probe packets are declared lost 1s after they are sent. This value
can be reduced, once implement proper retransmission logic for lost path
probes.

Reduces memory usage by replacing a fixed-capacity channel (256) with a
