Fix race conditions in differential evolution (#1063)

Browse Source 
Through a combination of silly mistakes, I missed a pile of race conditions in the OpenMP threading.

Switch to C++ threading. Note that this change requires serial generation of trial vectors.

Hopefully I can figure out to parallelize the generation of trial vectors to reduce the serial section a la Ahmdahl's law,
while simultaneously keeping thread sanitizer happy.
