Memory Leak in ifo_read.c

Hi,

I'v just fixed two memory leaks in ifo_read.c of libdvdread locally.
Here is how and I hope it will be usefull.

1. In ifoClose(ifo_handle_t *ifofile), after 
  ifoFree_VTS_PTT_SRPT(ifofile);
add a line
  ifoFree_VTS_TMAPT(ifofile);

2. In ifoFree_PGCIT_internal(pgcit_t *pgcit) ,
change
    for(i = 0; i < pgcit->nr_of_pgci_srp; i++)
      ifoFree_PGC(pgcit->pgci_srp[i].pgc);
to
    for(i = 0; i < pgcit->nr_of_pgci_srp; i++)
    {
      ifoFree_PGC(pgcit->pgci_srp[i].pgc);
      free(pgcit->pgci_srp[i].pgc);
    }

Xiaoyu.
