This part was fixed several times since commit aade4edc1 ("BUG/MEDIUM:
mux-h2: Don't handle pending read0 too early on streams") and there are
still some cases where a read0 event may be ignored because a partial frame
inhibits the event.
Here, we must take care to set H2_CF_END_REACHED flag if a read0 was
received while a partial frame header is received or if the padding length
is missing.
To ease partial frame detection, H2_CF_DEM_SHORT_READ flag is introduced. It
is systematically removed when some data are received and is set when a
partial frame is found or when dbuf buffer is empty. At the end of the
demux, if the connection must be closed ASAP or if data are missing to move
forward, we may acknowledge the pending read0 event, if any. For now,
H2_CF_DEM_SHORT_READ is not part of H2_CF_DEM_BLOCK_ANY mask.
This patch should fix the issue #1328. It must be backported as far as 2.0.
