When opening HTTP streams, and reading the headers, we currently discard header lines longer than `HTTP_HEADER_BLOCK_SIZE` (1024 bytes). While this is not generally forbidden by RFC 7230, section 3.2.5, it is not generally allowed either, since that may change the "message framing or response semantics". We thus fix this by allowing arbitrarily long header lines.

This is the likely better alternative to PR #6676.
