Land Recent QUIC Changes.

QUIC refactor to move the receive algorithm from QuicCongestionManager
into the ReceivedPacketManager.

Part of a larger congestion control refactor.

Fix bug in cl/57315483 in which TerminateFromPeer(true) was turned into
CloseReadSide().  This looks correct, except that QuicSpdyServerStream
overrides this method so it wasn't being called.

Rename QuicStreamSequencer::IsHalfClosed -> IsClosed. The sequencer only
has one path so it doesn't make much sense for it to be "half" closed.

Rename ReliableQuicStream::IsHalfClosed -> IsDoneReading
because the semantics are such that "IsHalfClosed" returned true when
the fin had been read, but before the read side had actually been
closed, which is confusing.

Rename two QUIC methods, no behavior change.

The QuicAckNotifier should only be attached to a stream frame if the
stream frame contains data. If we didn't consume any data (e.g. it is a
FIN only frame), then attaching it to the frame results in
use-after-delete.

Fix use-after-delete in QuicAckNotifier.

Removed the unused compressed parameter from CreateSynStream,
CreateSynReply and CreateHeaders methods.

Code cleanup, no behavioural change.

Removing unnecessary received_truncated_ack_ local variable now that
acks have an explicit truncation flag.

Change the Beta value used to reduce the TCP cubic congestion window in
QUIC to 1/12, the same as SPDY.
