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: The state machine logic is quite abstruse, this modifies it to make it more readable.

Summary:
QLogConnectionMigrationEvent:
Allow observing client-side ConnectionMigration attempts (replacing the
socket), and observing the server-side changing the peer address it
is writing to.
QLogPathValidationEvent:
Allow observing successful/failed path validation attempts.
Success is considered as a correct PathResponse being returned.
A Failure is only published on the timeout expiring, not an invalid
PathChallenge frame being returned (we do not cancel this).
There are already QlogEvents for PathChallenge/PathResponse that
can be observed.

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:
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:
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 is step 1 for removing reset on reset, since the send side may need to transition to waiting for a reset ack while the read side is an any state.
