Summary:
This iterates the mvfst version to be semantically equivalent to draft-27, and leaves support for the old mvfst version.
The client will not yet be moved to draft-27 by default.

Summary: This is without cipher dropping, but the frame is parseable and the server will send it at the correct time.

Summary:
This eliminatees some tech debt by completely removing the notion of version from the core transport parameters structure and the app token for zero rtt.
Note that for the draft-27 changes we will need to temporarily re-introduce it, but to a different layer (the extension encoding itself).

Summary: As it turns out these end up being hot functions. Most of the hotness is it taking the cache miss, but we're able to reduce it from .9% exclusive each to .1-.3% exclusive each by inlining it (which eliminates a `callq` instruction for each).

Summary: As a part of Draft 17, application close frame has been removed, we use connection close frame to represent both application close and connection close.

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:
Mostly need a bunch of folly::assume_unreachable() (sometimes
replacing __builtin_unreachable()). One place using designated initializers
that had to get commented out. Some headers replaced with folly portability ones.

Summary:
Prior to this we had an incorrect check for something being a stream frame. It technically should have worked for minimally encoded frame types, but would not work for a spec-incompliant frame type.
Instead of using a mask this makes it so each stream frame type is explicitly enumerated. This isn't as clean looking but is easier to validate as correct.
This also revealed some places where we were not correctly plumbing through the version for unit tests, so fixing those as a driveby.

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.
