Fix alloc_realloc UB
void ** does not exist: the address of a generic pointer is not properly defined (different pointer types may have different representations). So, alloc_realloc cannot exist as is without UB. Fortunately, it's not supposed to be used in the skalibs programming style, and skalibs itself only uses it in two places (stralloc_ready_tuned and stralloc_shrink) where the pointer is a char *. So we just fix the UB by making alloc_realloc() take a char **, and it's only defined for that pointer type. Nothing to see here folks, nothing happened at all.
