We rewrite static header table handling in nghttp2_hd.c. We expand nghttp2_token to include all static header table entries, and fully use them in header compression and decompression. The lookup function is now located in nghttp2_hd.c. We add new nghttp2_hd_inflate_hd2() function to export token value for header name, then we pass it to nghttp2_http_on_header function, so that we don't have to look up token there. We carefully set enum value of token to static table index, so looking up static table is now O(1), assuming we have token.
