Dead code removal.

Merge internal change: 87991626
https://codereview.chromium.org/987693006/

Add 'explicit' to the PacketWriterFactoryAdapter constructor, as
complained about by Lint.

Merge internal change: 87956343
https://codereview.chromium.org/988963002/

Adds an assert to confirm that QUIC's session flow control window is
always larger than the stream flow control window, and fixes some tests.

Merge internal change: 87837841
https://codereview.chromium.org/987943003/

Implement the "sanity checks" described in b/9509040:  Incoming packets
whose connection ID is not associated with a session and is not recorded
as being in time-wait state are tested for reasonableness before a
session is created for them.  This won't protect much against deliberate
DoS but will screen out a reasonable fraction of truly junk packets.

Add sanity tests so we do not create connections for initial packets
with truncated connection IDs.

Merge internal change: 87831756
https://codereview.chromium.org/981193003/

Change the null value for packet sequence numbers to
kInvalidPacketSequenceNumber (== 0), which cannot appear as a packet
sequence number.

Update QuicFecGroupTest::UpdateAndRevive and
QuicFecGroupTest::UpdateAndReviveOutOfOrder to generate packet numbers
starting with 1 rather than 0.

Change the null value for packet sequence numbers to
kNullPacketSequenceNumber (== 0).
