-/* Scratch buffers with a default stack allocation and fallback to
-   heap allocation.  It is expected that this function is used in this
-   way:
-
-     struct scratch_buffer tmpbuf;
-     scratch_buffer_init (&tmpbuf);
-
-     while (!function_that_uses_buffer (tmpbuf.data, tmpbuf.length))
-       if (!scratch_buffer_grow (&tmpbuf))
-         return -1;
-
-     scratch_buffer_free (&tmpbuf);
-     return 0;
-
-   The allocation functions (scratch_buffer_grow,
-   scratch_buffer_grow_preserve, scratch_buffer_set_array_size) make
-   sure that the heap allocation, if any, is freed, so that the code
-   above does not have a memory leak.  The buffer still remains in a
-   state that can be deallocated using scratch_buffer_free, so a loop
-   like this is valid as well:
-
-     struct scratch_buffer tmpbuf;
-     scratch_buffer_init (&tmpbuf);
-
-     while (!function_that_uses_buffer (tmpbuf.data, tmpbuf.length))
-       if (!scratch_buffer_grow (&tmpbuf))
-         break;
-
-     scratch_buffer_free (&tmpbuf);
-
-   scratch_buffer_grow and scratch_buffer_grow_preserve are guaranteed
-   to grow the buffer by at least 512 bytes.  This means that when
-   using the scratch buffer as a backing store for a non-character
-   array whose element size, in bytes, is 512 or smaller, the scratch
-   buffer only has to grow once to make room for at least one more
-   element.
