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.

The tools/perf/util/rbtree.c copy already drifted by three
csets:
4b324126e0c6c3a5080ca3ec0981e8766ed6f1ee
4c60117811171d867d4f27f17ea07d7419d45dae
16c047add3ceaf0ab882e3e094d1ec904d02312d
So remove the copy and use the lib/rbtree.c directly, sharing
the source code while still generating a separate object file,
since tools/perf uses a far more agressive -O6 switch.

So that we can filter by dso. Symbols in other dsos won't be
accounted for.
