[PATCH] alloc_buffer: Return unqualified pointer type in alloc_buffer_next

[Florian Weimer]

* Florian Weimer:

> alloc_buffer_next is useful for peeking to the remaining part of the
> buffer and update it, with subsequent allocation (once the length
> is known) using alloc_buffer_alloc_bytes.  This is not as robust
> as the other interfaces, but it allows using alloc_buffer with
> string-writing interfaces such as snprintf and ns_name_ntop.
