Subject: [PATCH v2 0/1] perf mem: improves DSO long names search speed with RB tree

v1->v2:
 - Rename DSO longname RBtree find function to segregate its two different
   uses of searching and linking DSO into RB tree.

This patch addes a RBtree to sort the DSO structures of the perf tool
by its long name so that searching for a match will be much quicker
especially if a large number of DSOs are beining profiled.
