Landing recent QUIC changes until 7:19 PM, Feb 26, 2016 UTC-5.

relnote: Deprecate --FLAGS_quic_use_stream_sequencer_buffer.

Merge internal change: 115699221
https://codereview.chromium.org/1764913002/#ps20001

Merge internal change: 115690862
https://codereview.chromium.org/1766623002/#ps20001

relnote: Make QUIC version negotiation stateless. The QUIC dispatcher now detects version mismatch before creating a QUIC session and sends out a version negotiation packet at that point. Protected by --Flag_quic_stateless_version_negotiation

Merge internal change: 115603675
https://codereview.chromium.org/1761253002/#ps20001

relnote: Reserve exactly enough space for QUIC timestamps in QuicAckFrame. received_packet_times.  No functional change.

Merge internal change: 115591435

relnote: Remove single line virtual methods that are not overridden anywhere.

QUIC client change.

Merge internal change: 115591067
https://codereview.chromium.org/1761643004/#ps20001

relnote: QUIC toy client/server change

Replace custom client packet reading code with call to
QuicPacketReader::ReadAndDispatchSinglePacket

Merge internal change: 115551866
https://codereview.chromium.org/1760423002/#ps20001

relnote: Remove virtual keyword from QuicSpdyStream::WriteTrailers.

Merge internal change: 115456160
https://codereview.chromium.org/1745303003/#ps40001

relnote: Switch to unique_ptr<GURL> for request uri in SpdyBalsaUtils::RequestHeadersToSpdyHeaders(). No function change.

Merge internal change: 115455799
https://codereview.chromium.org/1749303002/#ps40001

relnote: QUIC toy client/server changes

Adds a QuicSocketUtils::CreateUDPSocket method, and rename the existing
client/server CreateUDPSocket methods to be a bit more descriptive.

Merge internal change: 115444705
https://codereview.chromium.org/1752823002/#ps40001

relnote: Remove an unused declaration of QuicAckNotifier.

Merge internal change: 115400573
https://codereview.chromium.org/1751923003/#ps40001

relnote: Added new method OnStreamEnd to SpdyFramerVisitorInterface, stubbed implementations, No functional change.

Added a new visitor interface method to the SpdyFramerVisitorInterface
with signature:

  virtual void OnStreamEnd(SpdyStreamId stream_id) = 0;

Stubbed the new method in all implementors.

The eventual goal is to use the new method to handle stream ends
consistently, removing the need for fin boolean arguments in the other
methods in the visitor.

Merge internal change: 115370186
https://codereview.chromium.org/1749203002/#ps40001

relnote: Deprecate --FLAGS_quic_distinguish_incoming_outgoing_streams.

Merge internal change: 115342288
https://codereview.chromium.org/1755663002#ps60001

relnote: Remove unnecessary ReadPacket method.

Merge internal change: 115339832
https://codereview.chromium.org/1750303003/#ps60001

relnote: Deprecate --FLAGS_quic_supports_trailers

Merge internal change: 115244730
https://codereview.chromium.org/1753453003

relnote: Add 3 Quic e2e tests of server push. No behavior change.

Merge internal change: 115228444
https://codereview.chromium.org/1746803003

relnote: QuicSession::CreateIncomingDynamicStream now retains ownership of the created stream. No functional change.

Adds the ActivateStream call to CreateIncomingDynamicStream, which makes
it behave in a similar way to CreateOutgoingDynamicStream. Both methods
now retain ownership of the created stream (ActivateStream adds it to
the dynamic_stream_map_).
