There are ifdefs at several places to only define TRC_ARGS_QCON when
QUIC is defined, but nothing prevents this code from building without.
Let's just remove those ifdefs, the single "if" they avoid is not worth
the extra maintenance burden.
Prepare trace support for quic_conn instances as argument. This will be
used by the xprt-quic layer in replacement of the connection.
This commit is part of the rearchitecture of xprt-quic layers and the
separation between xprt and connection instances.
Sometimes it would be nice to be able to only trace abnormal events such
as protocol errors. Let's add a new "error" level below the "user" level
for this. This will allow to add TRACE_ERROR() at various error points
and only see them.
There are list definitions everywhere in the code, let's drop the need
for including list-t.h to declare them. The rest of the list manipulation
is huge however and not needed everywhere so using the list walking macros
still requires to include list.h.
This patch fixes all the leftovers from the include cleanup campaign. There
were not that many (~400 entries in ~150 files) but it was definitely worth
doing it as it revealed a few duplicates.
