Land Recent QUIC changes.

Minor style change for initialization of hdr.msg_flags.

Merge internal change: 49828095

Enabled MaxNumStreams in quic/tools area.

Renamed MaxNumConnections to MaxNumStreams. Initialize
set_max_streams_per_connection only in MaxNumStreams, not for all tests.

QUIC - Adding a bit more information to a logged DFATAL.

Merge internal change: 49724887

Always expecting certificates for secure quic (test) clients. Changing
the end_to_end test to be insecure as it doesn't configure certs.

Merge internal change: 49713074

Fail to process a header when the fec group offset is larger than the
packet sequence number.

Merge internal change: 49677837

Added a test to ensure that if the QuicPacketCreator has room for the
stream frame it can be added.

Merge internal change: 49620569

Adding support to QUIC for QUIC_VERSION_7, enabling lower overhead stream frames.

Merge internal change: 49540337

Rearrange code to match spdy_protocol.h SpdyFrameType declaration
order: mostly method declarations and definitions and case statements.

Merge internal change: 49503521

Refactor QuicReceivedEntropyManager and the other received packet code
into Quic ReceivedPacketManager to allow the entropy state and the ack's
received info to stay in sync.

Merge internal change: 49440136

Made a copy of QuicReceivedEntropyManager*.* code into QuicReceivedPacketManager*.*

Doing a better job of detecting unrecoverable compression state.

This is really tricky to get right.

We don't want to unilaterally close the connection if a stream closes before
headers are decompressed. If, for example, a server gets a protocol-layer
error while processing a request it could kill of a stream with something
like QUIC_MULTIPLE_TERMINATION_OFFSETS without sending the http/spdy
response. In this case, the client could continue processing on that
connection.

We basically want to kill off the connection if we get any packets for a
stream we've closed without processing complete headers. Which means
tracking state for every stream which closes without processing complete
headers which is a very unlikely OOM attack vector. I'm capping it at 20
somewhat arbitrarily, and calling it a day.

Removing logspam from quic connection.

Merge internal change: 49370853

Altering the server to not process headers until full headers have been read.

This fixes a problem where if we parsed partial headers, found an error, and
rejected the stream before getting full headers it would be possible to doom
the entire connection.
