The expected test output is with the headers decompressed, which
we can't do without Nghttp2. (It outputs the compressed headers
if we don't have it, so we could test for that instead.)
Fix#18707
Field blocks (carried in HEADERS, PUSH_PROMISE, and CONTINUATION
frames) are compressed by HPACK. Send them to the follow tap only
after decompression. Update the tests to match the new output.
Ping #18239 (There's still the case of gzip and brotli compressed
DATA frames to handle).
"Follow Stream" functionality assumes that all data in a single packet
belongs to the same stream. That is not true for HTTP2 and QUIC, where
we end up having data from unrelated streams.
Filter out the unwanted data directly in the protocol dissector code with
a custom `tap_handler` (as TCP already does).
Close#16093
