MINOR: mux-h2/trace: report a few connection-level info during h2_init()
It is currently very difficult to match some H2 trace outputs against
some log extracts because there's no exactly equivalent info.
This patch tries to address this by adding a TRACE_USER() call in h2_init()
that is matched in h2_trace() to report:
- connection pointer and direction
- frontend's name or server's name
- transport layer and control layer (e.g. "SSL/tcpv4")
- source and/or destination depending on what is set
This now permits to get something like this at verbosity level complete:
