the sockaddr struct for named sockets is defined like this ( on my mac )


struct    sockaddr_un {
    unsigned char    sun_len;    /* sockaddr len including null */
    sa_family_t    sun_family;    /* [XSI] AF_UNIX */
    char        sun_path[104];    /* [XSI] path name (gag) */
};

the sun_len value is ignored.
but the total length of the struct passed to bind / connect
should include it.

without this fix, the second time i run './osmocon'  it will complain:
Failed to bind the unix domain socket
since it tried to unlink the correct name, but called bind with a one
char too short name.
