Land Recent QUIC changes.

This is the first part of the code to allow faster stats/future
compression stuff to register for a notification when a block of data
has been fully ACKed by the peer.

The idea is as follows:

Someone who wants to be notified when their data is ACKed calls
SendStreamDataAndNotifyWhenAcked instead of SendStreamData, and provides
a Closure.

The QuicConnection stores the Closure in a QuicAckNotifier, and
maintains a vector of these.

On every ACK frame received, the OnAck(acked_seqnums) method of each
QuicAckNotifier is called. The QuicAckNotifier keeps track of the
sequence numbers it is waiting to see, and after being notified of all
of them it calls the Closure's Run() method.

Merge internal change: 51476134

Changed SourceAddressToken's code not to include port number while
performing crypto handshake (found in EndToEnd unit tests).

Use IPAddressToPackedString for source address token comparison.


Add CryptoServerConfig::set_strike_register_no_startup_period() to allow
a QuicServer to start accepting 0-RTT handshakes without waiting
a startup period.

Add an end-to-end test for a successful 0-RTT handshake.

Merge internal change: 51419595

Copying the overly-lenient SPDY workarounds to handling priority blocked
streams for idle timeout logic.

Merge internal change: 51406984

For this CL, the only chromium side change is to add
QuicConnectionPeer::SetPeerAddress.

Log packet retransmissions to DLOG(INFO). Use the standard format for
the log messages for crypto handshake messages on the client side.

Merge internal change: 51336227

New frame ID scheme to eliminate conflict between STREAM and PADDING
frames. PADDING frames are now stream type 0. Description of the new
scheme is in quic_framer.cc.

Merge internal change: 51271708

Fixing a bug in implicitly created streams which results in early packet
loss causing all streams to hang.
