MEDIUM: thread: set DEBUG_THREAD to 1 by default

Browse Source 
Setting DEBUG_THREAD to 1 allows recording the lock history for each
thread. Tests have shown that (as predicted) the cost of updating a
single thread-local variable is not perceptible in the noise, especially
when compared to the cost of obtaining a lock. Since this can provide
useful value when debugging deadlocks, let's enable it by default when
threads are enabled.
