Implementation of simple IO test application for LEMON and LIME
fully generalize number of test configurations in test_io
add another read iteration in the reread loop
add another failure type to test_io
IO test randomized and more complete checksum checks added
make MPI barrier dependent on delay
use new gauge exchange in test_io
print read failure output only on proc_id == 0
include unistd.h in test_io
NUM_READS not used in test_io anymore
correctly reset delay in test_io
fix compilation bug of init_openmp.c relating to existence of omp_num_threads and omp_get_num_threads() when compiling without OpenMP
