The commit 744451c7c ("BUG/MEDIUM: mux-h1: Properly detect full buffer cases
during message parsing") introduced a regression if trailers are not
received in one time. Indeed, in this case, nothing is appended in the
channel buffer, while there are some data in the input buffer. In this case,
we must not request more room to the upper layer, especially because the
channel buffer can be empty.
To fix the issue, on trailers parsing, we consider the H1 stream as
congested when the max size allowed is reached. Of course, the H1 stream is
also considered as congested if the trailers are too big and the channel
buffer is not empty.
This patch should fix the issue #1657. It must be backported as far as 2.0.
