MEDIUM: mux-h1: Rely on the H1C to deal with shutdown for reads

read0 is now handled with a H1 connection flag (H1C_F_EOS). Corresponding
flag was removed on the H1 stream and we fully rely on the SE descriptor at
the stream level.

Concretly, it means we rely on the H1 connection flags instead of the
connection one. H1C_F_EOS is only set in h1_recv() or h1_rcv_pipe() after a
read if a read0 was detected.
