Summary:
Currently, before server generate the destination CID, we route packets with client's address, port and client's source connection ID. But now that client can use 0-len source connection ID, the different connections from the same client address and port will be routed to the same server connections.
This diff changes it to use client's initial destination connection ID as part of the routing key.

Summary:
In the current client code we read one packet, go back to epoll, and then read
another packet. This is not very efficient.
This changes it so that we can read multiple packets in one go from an epoll
callback.
This only performs changes on the client

Summary:
It was hard to understand which names refer to which limits.
This diff makes it simple:
* conn.transportSettings.selfActiveConnectionIdLimit
represents how many of its peer's connection ids it will hold. It sends this to
the peer as the active_connection_id_limit
* conn.peerActiveConnectionIdLimit represents the value the peer sends as its
active_connection_id_limit. This should be defaulted to 0 and only changed
when we receive the transport parameters

Summary:
Use the helper function from earlier to create new connection id with sequence
number, and stateless reset token.
Add each of those new connection ids to the routing callback. Add a CHECK()
for routingCallback, because it should be set.
Add a new parametrized set of tests, to test the value of the
active_connection_id_limit transport parameter sent from client.

Summary:
My goal in this stack is to properly support the functionality of issuing new
connection ids.
There are at least three cases in which this is done (server-side):
* generate initial server connection id based on host id parameters
* provide several NewConnectionId frames to the client (for use with
migration) after handshake
* responding to RetireConnectionIdFrame and issuing more NewConnectionId frames
as needed
**Changes**:
* move connIdAlgo away from parent ConnectionStateBase to just
QuicServerConnectionState
* create virtual function in ConnectionStateBase to generate
folly::none ConnectionIdData by default,
and server subclass will generate a new server id
* add unit tests to test this behaviour.
Intended for Junqi's diff of server issuing 7 new connection ids
to be rebased on this (D15178642)

Summary:
This diff is the one that introduces+passes the test of multiple server conn
ids routing to a single transport.
Currently, there is still only one time in non-test code that more than one
server connection id is added. This diff ensures when we call connectionUnbound
we remove all associated connection ids.

Summary:
Currently, there is a 1:1 relationship between conn Id and transports. So for
all connections with a bound connection id, we iterate over all
connectionIdMap_ entries and delete the associate transport.
This won't work if connectionIdMap_ will map multiple conn ids to a single
transport.

Summary:
Add new data structure, `ConnectionIdInfo` which is will store
ConnectionId, folly::SocketAddress, and uint64_t sequenceNumber.
Add `addConnectionId()` method to QuicServerTransport, which will both
create+add a `ConnectionIdData` object to `ServerConnectionIds` and
call `routingCb_->onConnectionIdAvailable`.
Add a matching-source address check in QuicServerWorker when matching
based on ConnectionId.
Update QuicServerTest to test for change of address on one conn id.
Right now the semantics (apart from dropping mismatched source addresses
on the same connection id) are the same. Only one conn id can ever be added.
After this, we need to allow the QuicServerWorker to
hold a list of transports. Right now, `shutdownAllConnections()` works
because the mapping of conn Id<->transport is 1:1.

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.
