[collectd] Possible collectd bugs

[Brian Micek]

I am brand new to this mailing list and apologize if I am mentioning known 
issues.  We believe we may have stumbled on some minor bugs and would like to 
bring them to the attention of the developers.

In collectd.c near line 95, observe:
ERROR ("Looking up \"%s\" failed. You have set the "
                                "\"FQDNLookup\" option, but I cannot resolve "
                                "my hostname to a fully qualified domain "
                                "name. Please fix you network "
                                "configuration.");

The "C" string '%s' doesn't have an argument.  Please consider:
ERROR ("Looking up \"%s\" failed. You have set the "
                                "\"FQDNLookup\" option, but I cannot resolve "
                                "my hostname to a fully qualified domain "
                                "name. Please fix you network "
                                "configuration.",
                                hostname_g ? hostname_g : "NULL-Hostname" );

In ping.c near line 111 in the function ping_init(), observe liboping is not 
initialized.  In particular, the static pointer "pingobj" which describes the 
state of the plugin is not initialized.   Please consider this change:

static int ping_init (void)
{
         pingobj = ping_construct(); 
         if (hosts != NULL)
                add_hosts ();
         return (0);
 }

Thank you,
