Rusty Russell aca2e4f722 common/memleak: add dynamic hooks for assisting memleak.
Rather than reaching into data structures, let them register their own
callbacks.  This avoids us having to expose "memleak_remove_xxx"
functions, and call them manually.

Under the hood, this is done by having a specially-named tal child of
the thing we want to assist, containing the callback.

Rusty Russell 5591c0b5d8 gossipd: don't send gossip stream, let per-peer daemons read it themselves.
Keeping the uintmap ordering all the broadcastable messages is expensive:
130MB for the million-channels project.  But now we delete obsolete entries
from the store, we can have the per-peer daemons simply read that sequentially
and stream the gossip itself.

This is the most primitive version, where all gossip is streamed;
successive patches will bring back proper handling of timestamp filtering
and initial_routing_sync.

We add a gossip_state field to track what's happening with our gossip
streaming: it's initialized in gossipd, and currently always set, but
once we handle timestamps the per-peer daemon may do it when the first
filter is sent.

Rusty Russell a40f45af55 connectd: generate message for lightningd inside peer_connected().
We used to generate this in the caller, then save it in case we needed
to retry.  We're about to change the message we send to lightningd, so
we'll need to regenerate it every time; just hand all the extra args
into peer_connected() and we can generate the `connect_peer_connected`
msg there.

This fixes block parsing on testnet; specifically, non-standard tx versions.

Rusty Russell 7fad7bccba common/amount: new types struct amount_msat and struct amount_sat.
They're generally used pass-by-copy (unusual for C structs, but
convenient they're basically u64) and all possibly problematic
operations return WARN_UNUSED_RESULT bool to make you handle the
over/underflow cases.

The new #include in json.h means we bolt11.c sees the amount.h definition
of MSAT_PER_BTC, so delete its local version.

Rusty Russell 26dda57cc0 utils: make tal_arr_expand safer.
Christian and I both unwittingly used it in form:

	*tal_arr_expand(&x) = tal(x, ...)

Since '=' isn't a sequence point, the compiler can (and does!) cache
the value of x, handing it to tal *after* tal_arr_expand() moves it
due to tal_resize().

The new version is somewhat less convenient to use, but doesn't have
this problem, since the assignment is always evaluated after the
resize.
