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:
Don't use IOBufQueue for most operations in mvfst and use BufQueue instead. Since BufQueue did not support a splitAtMost, added it in instead.
The only place that we still use IOBufQueue is in crypto because fizz still requires it

They are strongly coupled, which indicate this is probably better to do it as one class.

Summary:
Create a custom type for read frame types. This allows us to reduce size of code.
We use a macro to generate new variant types whenever we need to.

Summary:
Remove the variant type for RegularQuicPacket and VersionNegotiationPacket.
This allows us to move version negotiation parsing to be only used on the client and only done explicitly
before a version is negotiated.

Summary:
Make a custom variant type for PacketHeader. By not relying on boost::variant
this reduces the code size of the implementation.
This uses a combination of a union type as well as a enum type to emulate a variant

Summary:
The CryptoFactory is extended with makePacketNumberCipher . In order to support that feature, FizzCryptoFactory now explicitly takes a QuicFizzFactory as argument instead of a generic fizz::Factory, which is the only type that is used in practice anyways.
The cypher argument was removed because:
1/ Only one cypher is used at all. Fizz also supports ChaCha20, but using it in mvfst will throw an exception.
2/ it seems like the factory should know what cypher it is dealing with.
If a choice of cypher needs to be supported going forward, it can be done by adding state to FizzCryptoFactory.

Summary:
This introduce the CryptoFactory abstraction that compute keys and AEAD to be used by most of mvfst.
The fizz specific parts are abstracted into a subclass, FizzCryptoFactory, and accessed using virtual methods.
Next step is to introduce QuicFizzFactory 's features into this abstraction.

Summary:
Draft-22 onwards uses two one byte length fields to encode connection ID length instead of one one byte length field.
To support this without disrupting existing clients we need to make our parsing version dependent. This diff accomplishes it by special casing the existing Facebook client QUIC version (0xfaceb000), and changing the default Facebook client version going forward to 0xfaceb001.
Note that this diff also changes the behavior of the ticket transport parameters. When we changed from draft-18 to draft-19 transport parameters I apparently forgot to update the ticket transport parameters to the new format.

Summary:
This introduce quic::Aead as a simple typedef to fizz::Aead and update the codebase to use quic::Aead . This should not impact the functionality of the code in any way.
This is a first step toward introducing an interface that is specific for mvfst so that mvfst can swap fizz for something else.
