With AutoConnect = yes, tinc tries to establish connections to known hosts.
However, you could have set no Address for this host, which is perfectly fine
(as long as there is at least one bootstrap node with an address or a local
discovered node already part of the network)
So log this to LOG_DEBUG
In a "decentrally managed vpn" it is very likely that host config
files for some reachable nodes do not exist. Currently, tinc
fills the logs with "Cannot open config file" messages.
This commit changes the log level to LOG_DEBUG so
syslog doesn't get filled by default.

To compile the test you will need cmocka installed on system.
Checks in configure.ac are still missing.
$ cd tinc/test/; make simple
to generate testing directory you can use cmocka-simple.sh
$ ./cmocka-simple.sh
‘mocks/conf1’ -> ‘/tmp/tmp.PtS9r796ns/conf1’
To run the test do: cd /tmp/tmp.PtS9r796ns ; ./simple
$ ./simple
