The new logger is much more powerful, allows online log-filter
modifications and precise debugging. We still avoid heavy file-operations
as we rely on the caller to forward stderr to a log-file and perform
log-rotations. However, we now provide a simple way to perform this
forward inside the application.

config.h is meant to be around in all files, as it contains stuff like
_GNU_SOURCE, NDEBUG and HAVE_*.
Make these definitions available without needing to #include config.h
every single time.

log_warn is much shorter and we already use log_err instead of log_error
so this is more consistent now.

We simply forward all log messages to stderr. We use syslog/prink-like severity
prefixes. Use systemd or alike to forward stderr to syslog, kernel-log or
similar.
