Landing Recent QUIC changes until 8/4/2015 20:30 UTC.

Disable FLAGS_quic_require_handshake_confirmation for ZeroRTT test.

relnote: Adding FLAGS_require_handshake_confirmation to emergency-disable
QUIC 0-rtt

Adding a reloadable flag to allow quickly disabling QUIC's 0-rtt
handshake as an interim measure (0-rtt DoS protection) to allow
StrikeServer turndown before full DoSServer integration.  See b/20122788

Merge internal change: 99600488
https://codereview.chromium.org/1272153006/

relnote: Deprecate FLAGS_quic_send_fec_packet_only_on_fec_alarm.

Merge internal change: 99599597
https://codereview.chromium.org/1279433004/

relnote: Limit the number of burst tokens in QUIC's pacing sender to the
min of 10 and the current CWND in packets.

Protected by FLAGS_quic_limit_pacing_burst.

Should decrease retransmit rate for low CWND flows.

Preparation for changing SpdyHeaderBlock to be ordered. This just reduces
the number of files in upcoming CL by 2. No behavior change as these are
currently entries into a map, and the key:value pairs haven't changed.
However after changing to ordered SpdyHeaderBlock, the pseudo-header
order of authority,path,scheme,method is what ends up getting written,
and thus I'm changing the order here in advance.

relnote: n/a (test only)

Merge internal change: 99394725
https://codereview.chromium.org/1281463002/

relnote:  Close QUIC connections due to too many open streams earlier in
processing.  No significant behavior change.  Flag-protected by enabled
FLAGS_exact_stream_id_delta.

Replace the "maximum delta in stream ID" test on a newly-created stream
with an exact test for the max number of open streams.  Change the error
in this case from QUIC_INVALID_STREAM_ID to QUIC_TOO_MANY_OPEN_STREAMS.

relnote: Minor format changes to keep the code similar to internal source.

Merge internal change: 99250353
https://codereview.chromium.org/1274003002/

relnote: Change the QuicStreamSequencer to call OnDataAvailable instead
of OnFinRead when the fin is consumed.

Make ReliableQuicStream::OnFinRead() non-virtual and remove overrides in
subclasses.
