As reported by Tim in issue #1428, our sources are clean, there are
just a few files with a few rare non-ASCII chars for the paragraph
symbol, a few typos, or in Fred's name. Given that Fred already uses
the non-accentuated form at other places like on the public list,
let's uniformize all this and make sure the code displays equally
everywhere.
The STREAM data to send coming from the upper layer must be stored until
having being acked by the peer. To do so, we store them in buffer structs,
one by stream (see qcs.tx.buf). Each time a STREAM is built by quic_push_frame(),
its offset must match the offset of the first byte added to the buffer (modulo
the size of the buffer) by the frame. As they are not always acknowledged in
order, they may be stored in eb_trees ordered by their offset to be sure
to sequentially delete the STREAM data from their buffer, in the order they
have been added to it.
This should be used by the function which build packets to prevent
it from failing. This is important when the packet numbers are consumed
by several threads. The packet number is used to build and encrypt packets
and must be incremented only and only if the packet it refers to has been
successfully built.
This patch imports all the definitions for QUIC protocol with few modifications
from 20200720-quic branch of quic-dev repository found at
https://github.com/haproxytech/quic-dev.
