Notable changes:

- uv_get_constrained_memory() has been added.
- A race condition in uv_async_send() has been fixed.
- uv_get_free_memory() and uv_get_total_memory() now read from
  /proc/meminfo, which should improve correctness when called
  from inside an lxc container.
- A failed assertion in uv_fs_poll_stop() has been fixed.
- A bug in MAC addresses for IP-aliases has been fixed.

`node.h` may only include public APIs, which `util-inl.h` is not.
There does not seem to be any reason for including it, so remove it,
because otherwise native addon compilation is broken due to us not
shipping the `util-inl.h` header.
