Seems like LND is hanging up on receiving these messages, even though
they're odd :(
So, when a peer connects, check if it supplies or wants peer backup
(even if it doesn't support both, it shouldn't hang up, and I didn't
want to separate the two paths).
And when we go to send our own, updated backup, check features before
sending.

Changelog-EXPERIMENTAL: `experimental-peer-storage` caused LND to hang up on us, so only send to peers which support it.
This commit will disable the peerstorage plugins
when the feature is not enabled.
I found this issue with lnprototest, and I guess
we did not find it with normal run because
other the unknown messages are ingored?

Since it's not spec-final yet (hell, it's not even properly specified
yet!) we need to put it behind an experimental flag.
Unfortunately, we don't have support for doing this in a plugin; a
plugin must present features before parsing options. So we need to do
it in core.

When you return an allocated pointer, you should always hand in the
context you want it allocated from. This is more explicit, because it may
really matter to the caller!
This also folds some simple operations, and avoids doing too much
variable assignment in the declarations themselves: some coding styles
prohibit such initializers, but that's a bit exteme.

And we should always represent them as is, not as optional: it's
possible in future we could *require* "WANT_PEER_BACKUP_STORAGE".

We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.
Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)
