Added thread naming in taped.

The different processes of taped can now be identified as in this exemple:
[eric@localhost ~]$ ps -ax -o "pid comm cmd"  | grep /usr/bin/cta-taped
32593 cta-taped-main  /usr/bin/cta-taped -fl /cta-taped.log
32800 cta-tpd-VDSTK11 /usr/bin/cta-taped -fl /cta-taped.log
32801 cta-taped-gc    /usr/bin/cta-taped -fl /cta-taped.log
