filter.

21d2041da0 Back off on generating noise in the event of a PING frame
If either endpoint issues a PING frame while we are introducing noise
into the communication then there is a danger that the connection itself
will fail. We detect the PING and then back off on generating noise for a
short while. It should be sufficient to just ensure that the next datagram
does not get dropped for each endpoint.

523c5a06c5 Clarify the terminology in the noisy dgram BIO
The previous terminology was quite confusing. We try to use drop, duplicate
and delay more consistently and introduce the "reinject" terminology as a
mechanism for implementing duplicates and delays.

35bd8a6004 Add a packet splitting BIO
Provide a BIO filter that can split QUIC datagrams containing multiple
packets, such that each packet is in its own datagram.

d3a8daca58 Use test_random() to introduce better noise into the noisy dgram BIO
We drop some datagrams, and we delay some datagrams. We can also duplicate
some datagrams.

43b94c7fe4 Create a noisy dgram test
Create a noisy dgram test that can drop/duplicate/reorder UDP packets and
ensure that the QUIC connection is tolerant of this. At this stage we just
create the outline of the test. Adding in the noise will come in future
commits.
