The main CLI I/O handle is responsible to interrupt the processing on
shutdown/abort. It is not the responsibility of the I/O handler of CLI
commands to take care of it.
Extend "show quic" to be able to dump MUX related information. This is
done via the new function qcc_show_quic(). This replaces the old streams
dumping list which was incomplete.
These info are displayed on full output or by specifying "mux" field.
Add the possibility to customize show quic full output with only a
specific set of printed fields. This is specified as a comma-separated
list. Here are the currently supported values :
* tp: transport parameters
* sock: connection addresses and socket FD
* pktns: packet number space with ack ranges and in flight bytes
* cc: congestion controler and loss information
Note that streams output is not filtered by this mechanism. It's because
it will be replaced soon by an output generated from the MUX which will
use its owned field name.
Add the possibilty to restrict show quic output to only a single
connection. This is done by specifying a quic_conn address pointer.
Default format selection has evolved with it. Indeed, it seems more
fitting to use full format by default when filtering on a connection.
However, it's still possible to revert to the original oneline format
with it by specifying it explicitely.
Output of 'show quic' is messed up since the introduction of reordered
packets counter in the following commit. The new counter is mixed up
with the first stream line. This is due to the wrong placement of the
newline delimiter.

MINOR: quic: Add a counter for reordered packets
This should be backported up to 2.6.
A packet is considered as reordered when it is detected as lost because its packet
number is above the largest acknowledeged packet number by at least the
packet reordering threshold value.
Add ->nb_reordered_pkt new quic_loss struct member at the same location that
the number of lost packets to count such packets.
Should be backported to 2.6.
This date is shared between the idle timer and hanshake timeout. So, it should be
useful to dump the expiration date of the idle timer task itself, in place of the
idle timer expiration date. This way, the handshake timeout value will be visible
during the handshake from CLI "show quic full" command.
Due to the fact that several variable values (rtt_var, srtt) were stored as multiple
of their real values, some calculations were less accurate as expected.
Stop storing 4*rtt_var values, and 8*srtt values.
Adjust all the impacted statements.
Must be backported as far as 2.6.
