Avoid loop for common memory operations (zeroing, copying, moving).

Use the proper function for common memory operations (memset() for
zeroing, memcpy() for copying, memmove() for moving), instead of
looping through arrays.

By extension, remove loops to reset arrays when they were allocated
with calloc() and thus already zeroed.
