There was a colorful mix of header guards - standardize them.

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:

 4b324126
 4c601178
 16c047ad

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.
