pack-objects: use free()+xcalloc() instead of xrealloc()+memset()
Whenever the hash table becomes too small then its size is increased, the original part (and the added space) is zerod out using memset(), and the table is rebuilt from scratch. Simplify this proceess by returning the old memory using free() and allocating the new buffer using xcalloc(), which already clears the buffer for us. That way we avoid copying the old hash table contents needlessly inside xrealloc(). While at it, use the first array member with sizeof instead of a specific type. The old code used uint32_t and int, while index is actually an array of int32_t. Their sizes are the same basically everywhere, so it's not actually a problem, but the new code is cleaner and doesn't have to be touched should the type be changed.
