In QUIC client, use normalized server address to determine whether a packet is from unknown server.

The current code can fail if direct_peer_address_ is a dual stacked address and
last_received_packet_info_.source_address is a normal v4 address. This has been observed in GFE custom prober test.

Protected by FLAGS_quic_test_peer_addr_change_after_normalize.

QUICHE stands for QUIC, Http, Etc. It is Google‘s production-ready implementation of QUIC, HTTP/2, HTTP/3, and related protocols and tools. It powers Google’s servers, Chromium, Envoy, and other projects. It is actively developed and maintained.

There are two public QUICHE repositories. Either one may be used by embedders, as they are automatically kept in sync:

To embed QUICHE in your project, platform APIs need to be implemented and build files need to be created. Note that it is on the QUICHE team's roadmap to include default implementation for all platform APIs and to open-source build files. In the meanwhile, take a look at open source embedders like Chromium and Envoy to get started:

QUICHE is only supported on little-endian platforms.
