ELSA 1.2.1 released

As connector is not included in the libc we need to include it through kernel source. The problem is that there is a conflit with some definitions in <time.h>. Some variable are defined in <sys/time.h> and redefined in <linux/time.h> (included in cn_proc.h). Thus we add a ugly #define to be able to compile. We will remove that hack as soon as libc includes connectors.
