The strlist__entry method allows accessing strlists like an array, will be used in the 'perf report' to access the first entry. We now keep the nr_entries so that we can check if we have just one entry, will be used in 'perf report' to improve the output by showing just at the top when we have just, say, one DSO. While at it use nr_entries to optimize strlist__is_empty by not using the far more costly rb_first based implementation.
