Summary: This commit removes ~10000 strlen calls and ~100000 memcpy calls in blender (profiled with blender --background), ~10000 memcpy calls in makesdna. There is no need to create null-terminated strings for atoi, because it converts only the initial portion of the string anyway. Also it was noticed that DNA_elem_array_size and arraysize functions work only with full strings, so there is no point to calculate strlen.
