ipsec: Put dumpers on the dump list
Herbert Xu came up with the idea and the original patch to make
xfrm_state dump list contain also dumpers:
As it is we go to extraordinary lengths to ensure that states
don't go away while dumpers go to sleep. It's much easier if
we just put the dumpers themselves on the list since they can't
go away while they're going.
I've also changed the order of addition on new states to prevent
a never-ending dump.
Timo Teräs improved the patch to apply cleanly to latest tree,
modified iteration code to be more readable by using a common
struct for entries in the list, implemented the same idea for
xfrm_policy dumping and moved the af_key specific "last" entry
caching to af_key.
