MEDIUM: mux-h1: Handle H1C states via its state field instead of H1C_F_ST_*

The H1 connection state is now handled in a dedicated state. H1C_F_ST_*
flags are removed. All states are now exclusives. It is easier to know the
H1 connection states. It is alive, or usable, if it is not CLOSING or
CLOSED. It is CLOSING if it should be closed ASAP but a stream is still
attached and/or the output buffer is not empty. CLOSED is used when the H1
connection is ready to be closed. Other states are quite easy to understand.

There is no special changes in the H1 connection behavior. Except in
h1_send(). When a CLOSING connection is CLOSED, the function now reports an
activity. In addition, when an embryonic H1 stream is aborted, it is
destroyed. This way, the H1 connection can be switched to CLOSED state.
