Subject: Remove usage of list iterator after the loop body

In preparation to limit the scope of a list iterator to the list
traversal loop, use a dedicated pointer as the iterator [1].

v1->v2:
- fix reverse x-mas tree (Steven Rostedt)
- rename subject line (Steven Rostedt)
- add additional tracing patches to bundle them all up in one go

Jakob Koschel (4):
  tracing: Remove usage of list iterator after the loop body
  tracing: Remove usage of list iterator variable after the loop
  tracing: Replace usage of found with dedicated list iterator variable
  tracing: Remove check of list iterator against head past the loop body
