tools/lib/lockdep: Add tests for AA and ABBA locking
Add test for AA and 2 threaded ABBA locking.
Rename AA.c to ABA.c since it was implementing an ABA instead of a pure
AA. Now both cases are covered.
The expected output for AA.c is that the process blocks and lockdep
reports a deadlock.
ABBA_2threads.c differs from ABBA.c in that lockdep keeps separate chains
of held locks per task. This can lead to different behaviour regarding
lock detection. The expected output for this test is that the process
blocks and lockdep reports a circular locking dependency.
These tests found a lockdep bug - fixed by the next commit.
