time is less than the packet's actual receive time.

Change the pacing sender to always pacing the initial burst, even when
an RTT sample hasn't been taken.

Set the server's idle timeout to 2s longer than the negotiated value(30s
by default) instead of 1s, in order to prevent failed requests.

Call SetDefaults from the QuicConfig constructor instead of requiring
all callers to do so.

Allow the number of undecryptable QUIC packets buffered before the
CHLO/SHLO to be configured in QuicConfig.

Remove QuicSentPacketManager::DebugVisitor's OnSentPacket, since it's
redundant to QuicConnection::DebugVisitor's OnPacketSent.

Refactored QuicConnection::DebugVisitor's OnPacketSent in order to add
necessary fields for the trace... visitor.

QUIC: if client provides an STK which includes CachedNetworkParams, then
store these and echo them back in future STKs if we have no newer
estimate to send. Flag protected behind disabled
FLAGS_quic_store_cached_network_params_from_chlo.

This is the followup to adding timestamp to the SourceAddressToken proto.
This allowed us to copy a previously provided CachedNetworkParams into
new STKs without losing timestamp data.

It also paves the way for recording BW estimate accuracy in the server:
we now have the client's provided BW estimate stored per connection, so
we can compare against BW that we see on the new connection (this will
be in a future CL).

Merge internal change: 76455340

chromium: this code doesn't impact client side code because we don't
parse SourceAddressToken (we keep it as a string). For QUIC server,
we are not parsing optional cached_network_params. Added a TODO
to convert SourcAddressToken and CachedNetworkParams to protobuf.
