Since SDS v2, we no longer have a single header, so the function to rewrite the SDS in terms of the minimum space required, instead of just using realloc() and let the underlying allocator decide what to do, was doing an allocation + copy every time the minimum possible header needed to represent the string was different than the current one. This could be often a bit wasteful, because if we go, for instance, from the 32 bit fields header to the 16 bit fields header, the overhead of the header is normally very small. With this commit we call realloc instead, unless the change in header size is very significant in relation to the string length.
