The ->li (struct listener *) member of quic_conn struct was replaced by a
->target (struct obj_type *) member by this commit:
MINOR: quic-be: get rid of ->li quic_conn member
to abstract the connection type (front or back) when implementing QUIC for the
backends. In these cases, ->target was a pointer to the ojb_type of a server
struct. This could not work with the dynamic servers contrary to the listeners
which are not dynamic.
This patch almost reverts the one mentioned above. ->target pointer to obj_type member
is replaced by ->li pointer to listener struct member. As the listener are not
dynamic, this is easy to do this. All one has to do is to replace the
objt_listener(qc->target) statement by qc->li where applicable.
For the backend connection, when needed, this is always qc->conn->target which is
used only when qc->conn is initialized. The only "problematic" case is for
quic_dgram_parse() which takes a pointer to an obj_type as third argument.
But this obj_type is only used to call quic_rx_pkt_parse(). Inside this function
it is used to access the proxy counters of the connection thanks to qc_counters().
So, this obj_type argument may be null for now on with this patch. This is the
reason why qc_counters() is modified to take this into consideration.
