[PATCH] more udev-016/extras/multipath

incremental to udev-016/extras/multipath-0.0.16.3,

        * add a GROUP_BY_SERIAL flag. This should be useful for
          controlers that activate their spare paths on simple IO
          submition with a penalty. The StorageWorks HW defaults to
          this mode, even if the MULTIBUS mode is OK.
        * remove unused sg_err.c
        * big restructuring : split devinfo.c from main.c. Export :
                * void basename (char *, char *);
                * int get_serial (int, char *);
                * int get_lun_strings (char *, char *, char *, char *);
                * int get_evpd_wwid(char *, char *);
                * long get_disk_size (char *);
          Now we see clearly what is expected from an external package
          like scsi_id.
        * stop passing struct env as param
