For Debian I would like to rework the default configuration, adding an include /etc/radsecproxy/includes.d/*.conf statement.

Unfortunately this fails if the directory does not contain any files matching the expression.
I can of course ship an empty dummy.conf file, but I would like to avoid that approach.

I propose to

• either change the behavior to not fail if a wildcard is used and nothing matches (still output some warning in debug mode)
• or introduce a new tryinclude statement, that behaves like outlined above, to not change the established statement.
