…der: Previously, incoming frames were placed on per-Stream queues, which were read from lazily, i.e. whenever HTTP20Response.getheaders() or .read() were called. However, the HPACK algorithm depends on header blocks being encoded/decoded in the same order on both sides of the connection; otherwise, the codec states on each peer will get out of sync. This commit rearranges header decoding by moving it from Stream.getresponse() to Stream.receive_frame(), which is executed on the Connection's event loop. DATA frame receiving was refactored in a similar way for consistency.
