You can now simply add per-tal-object helpers for memleak, but our older pattern required calling memleak functions explicitly during memleak handling. Hash tables in particular need to be dynamically allocated (we override the allocators using htable_set_allocator and assume this), so it makes sense to have a helper macro that does all three. This eliminates a huge amount of code. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
