Willy Tarreau a875466243 BUG/MEDIUM: mux-h2: mark that we have too many CS once we have more than the max 
Since commit f210191 ("BUG/MEDIUM: h2: don't accept new streams if
conn_streams are still in excess") we're refraining from reading input
frames if we've reached the limit of number of CS. The problem is that
it prevents such situations from working fine. The initial purpose was
in fact to prevent from reading new HEADERS frames when this happens,
and causes some occasional transfer hiccups and pauses with large
concurrencies.

Given that we now properly reject extraneous streams before checking
this value, we can be sure never to have too many streams, and that
any higher value is only caused by a scheduling reason and will go
down after the scheduler calls the code.

This fix must be backported to 1.9 and possibly to 1.8. It may be
tested using h2spec this way with an h2spec config :

  while :; do
    h2spec -o 5 -v -t -S -k -h 127.0.0.1 -p 4443 http2/5.1.2
  done
