Land Recent QUIC Changes.

Change QUIC's RTO implementation. Protected by FLAGS_quic_use_new_rto.

Decides whether to invoke SendAlgorithmInterface's
OnRetransmissionTimeout after an ack has been received instead of
pro-actively invoking it and then having to revert it.

Fix a minor QUIC bug when both quic_use_new_rto and
quic_rto_uses_last_sent were enabled, a spurious retransmission didn't
expire the SRTT.

Adds an alarm for sending a QUIC FEC packet.

This CL adds an alarm for sending an FEC packet. The alarm is based on
the connection's SRTT, and is set when the first FEC protected packet in
an FEC group is sent. This alarm puts some time between the sending of
an FEC protected packet and the corresponding FEC packet, to reduce the
probability of both these packets getting dropped in the network.

Tell the QUIC AckNotifierManager about packets on serialization, rather
than when successfully sent.
Protected by ENABLEd FLAGS_quic_ack_notifier_informed_on_serialized.
