Summary:
The fizz `encrypt` API will opportunistically use inplace encryption if the `IOBuf` you pass it is correctly sized. If it is not it will manually create the output buffer.
It turns out doing inplace versus encrypting with a given target output is a bit faster in microbenchmarks, and it will also allow experimenting with caching `IOBuf`s on the send path.

Summary:
Previously we stored an `IntervalSet` in each `WriteAckFrame`. We don't need to do this, as by the time we are writing an `ACK` the `IntervalSet` is complete. Instead of bothering with the `IntervalSet` operations, we can simply serialize it to a reverse-sorted `vector.`
Additionally this has some micro-optimizations for filling the ACK frame, with a new function for getting varint size.

Retry the original multiple recvmsg diff.
This has a few changes from the original:
1. Fixes happy eyeballs behavior by using the socket directly from the callback.
2. Fixes an error condition to make sure we unregister the callback on error
3. Makes the default to use the basic 1 message recv.

Summary:
This moves the fizz specific part of the handshake into its own folder and library.
There is a bit of smurf naming going on as a result, not sure it is worth fixing or not at this stage. Maybe this code should be a in namespace named quic::fizz .
This should be doable with the client as well as soon as the key cache situation is figured out.

Summary:
This test tries to construct a bad packet by using server CID as the
dest CID in a server to client packet. It hopes to verify client will fail
parsing and throw. It used to work fine.
Then a couple month ago, our client code switched to use 0-len client CID. Now
client always read 0 bytes out as Dest CID on received packet. But in this test
case server writes a >0 len CID into the packet as Dest CID since the test case
tries to construct a bad packet. Then client treats these bytes as frame bytes
since it assumes 0 len DestCID. Then it parse frames from there. Now sometimes
parsing fails and we throw from parsing. Sometimes parsing accidentally goes
through, then we may or may not throwing when we process the parsed frames.
For example, if we parse out a stream frame successfully with a local stream ID
that's not open, we throw from there. But sometimes, nothing gets throw, since
we can potentially, for example, parse out a stream frame with a remote stream
ID and just simply create it. Sometime the test just hangs, since the stream ID
is huge and we create thousands of streams.
It's hard to fix this test case and keep it unflaky. For example, I figured by
using (0, 5, 3) instead of (0, 0, 0) as the CID encoding params, the test always
passes. That's because the server generates a CID that will definitely fail
parsing on client side. But if some day draft changes the frame type ID values
again, the test will fail again. And someone else will have to go through this
debugging process all over again.
I think we can just remove this test case altogether.
