+struct bitvec *bitvec_alloc(unsigned int size, TALLOC_CTX * bvctx)
+{
+	struct bitvec *bv = talloc_zero(bvctx, struct bitvec);
+	bv->data_len = size;
+	bv->cur_bit = 0;
+	bv->data = talloc_zero_array(bvctx, uint8_t, size);

+}

talloc has hierachies. So we pass the context into it but bv->data should
be a child of "data". As a library function it needs to handle OOM as well.


	bv = talloc_zero(bvctx, struct bitvec);
	if (!bv)
		return NULL;
	bv->data_len = size;
	..
	bv->data = talloc_zero_array(bv, uint8_t, size);
	if (!bv->data) {
		talloc_free(bv);
		return NULL;
	}
	return bv
