Summary:
Mainly based on Junqi's changes in D15230415
Added the start of several error checking. Section 19.15
of d-23
(https://tools.ietf.org/html/draft-ietf-quic-transport-23#section-19.15)
specifies 2 cases where PROTOCOL_VIOLATION should be thrown during processing:
* retire_prior_to is larger than sequence number
* new_connection_id is sent by peer using 0-len conn id (will handle later)
I don't think it was specified what happens if we get a NEW_CONN_ID frame
after the the endpoint already has enough of the peer's conn ids - just ignore
the frame.

Summary:
Allow the client to set zero-length id for itself.
If enabled, saves 8 bytes (if packet isn't padded to minimum).
However, will be disabled if connection migration is enabled.
Main changes include updating the short header parsing to pass
in the connection id length, since unlike long headers,
short header's dst conn id isn't preceeded by length.
Created a new `QuicClientTransportAfterStartTestBase` class
to move `testing::WithParamInterface<>` inheritance to subclasses.
(Only one parameter per test class).

Summary:
Implement sending stream limit updates in a windowed fashion, so that as a peer exhausts its streams we will grant it additional credit. This is implemented by having the stream manager check if an update is needed on removing streams, and the api layer potentially sending an update after it initiates the check for closed streams.
This also makes some driveby changes to use `std::lower_bound` instead of `std::find` for the sorted collections in the stream manager.

Summary:
Removes clientConnId completely from ServerConnectionIdParams.
This diff first fixes an incorrect assumption; it calls
`shortHeader.getConnectionId()` which is actually the destination id (server)
not the client connection id.
Next, this entire block is unnecessary, because this will be called after
the transport is created, so the clientConnectionId will always be set.
This also setsconn.serverConnectionId earlier (shouldn't depend on
connClientId).

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:
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.

This introduces FizzAead as a wrapper for fizz::Aead that implements quic::Aead and forward all calls. Most of the codebase now uses quic::Aead, which a significant step toward being able to swap it for another implementation.
