The decoder is now fully functional. It makes use of the dynamic header table. Dynamic header table size updates are currently ignored, as our initially advertised value is the highest we support. Strictly speaking, the impact is that a client referencing a header field after such an update wouldn't observe an error instead of the connection being dropped if it was implemented. Decoded header fields are copied into a target buffer in HTTP/1 format using HTTP/1.1 as the version. The Host header field is automatically appended if a ":authority" header field is present. All decoded header fields can be displayed if the file is compiled with DEBUG_HPACK.
