[PATCH v4 00/26] ctx wide rsrc nodes +

[Pavel Begunkov <asml.silence@gmail.com>]

1-7 implement ctx wide rsrc nodes. The main idea here is to make make
rsrc nodes (aka ref nodes) to be per ctx rather than per rsrc_data, that
is a requirement for having multiple resource types. All the meat to it
in 7/7. Btw improve rsrc API, because it was too easy to misuse.

Others are further cleanups

v2: io_rsrc_node_destroy() last rsrc_node on ctx_free()
v3: the series is growing
v4: keep growing...
