Add "total" field.

Mon Oct 31 23:41:33 2005  Soeren Sandmann  <sandmann@redhat.com>

        * stackstash.h (struct StackNode): Add "total" field.

        * stackstash.c (stack_stash_add_trace): Keep track of the
        aggregate size.

        * profile.c (profile_get_size): Sum the totals of the siblings
        instead of all the children.

        * profile.c (build_object_list): Correctly compute obj->self

        * profile.c (profile_load): Don't ignore the node->total field.

        * profile.c (serialize_call_tree): Save node->total instead of the
        computed total

        * profile.c (compute_total): Use n->total instead of computing it
        from scratch.

        * profile.c: Remove unused sum_children() function.

        * TODO: Updates

        * process.c (process_get_from_pid): Plug leak.
