tools lib rbtree: pick some improvements from the kernel rbtree code
The tools/lib/rbtree.c code came from the kernel. Remove the
EXPORT_SYMBOL() that make sense only there. Unfortunately it is not being
checked with tools/perf/check_headers.sh. Will try to remedy this. Until
then pick the improvements from:
b0687c1119b4e8c8 ("lib/rbtree: use '+' instead of '|' for setting color.")
That I noticed by doing:
diff -u tools/lib/rbtree.c lib/rbtree.c
diff -u tools/include/linux/rbtree_augmented.h include/linux/rbtree_augmented.h
There is one other cases, but lets pick it in separate patches.
