MEDIUM: quic: implement quic-initial rules

Browse Source 
Implement a new set of rules labelled as quic-initial.

These rules as specific to QUIC. They are scheduled to be executed early
on Initial packet parsing, prior a new QUIC connection instantiation.
Contrary to tcp-request connection, this allows to reject traffic
earlier, most notably by avoiding unnecessary QUIC SSL handshake
processing.

A new module quic_rules is created. Its main function
quic_init_exec_rules() is called on Initial packet parsing in function
quic_rx_pkt_retrieve_conn().

For the moment, only "accept" and "dgram-drop" are valid actions. Both
are final. The latter drops silently the Initial packet instead of
allocating a new QUIC connection.

quic-initial <action>
Perform an action on an incoming QUIC Initial packet. Contrary to
"tcp-request connection", this is executed prior to any connection element
instantiation and starting and completion of the SSL handshake, which is more
efficient when wanting to reject connections attempts.
May be used in the following contexts: http
May be used in sections : defaults | frontend | listen | backend
yes(!) | yes | yes | no
Arguments :
<action> defines the action to perform if the condition applies. See
below.
This action is executed early during QUIC packet parsing. As such, only a
