This is in preparation for the next step.
Note that we now don't add it to the linked list of txs we've send
until after it's sent by the immediate callback; this means it won't
get broadcast by the timer until after it's been done by broadcast_tx.
Also, this means we no longer steal the tx in broadcast_tx(); but we'll fix
up the leaks 4 patches later.

We don't simply parent them on the object, we use a dummy object which tells
us not to call the callback if freed.
This would be better fixed by rewriting ccan/io to handle tal_free() of
a conn; then we could simply parent the entire thing and forget about it.

Three days of on and off debugging, before I realized my server was talking
to a non-testnet bitcoind. There was a bitcoind on that machine running
on testnet, but it uses the same dir and config, so the --bitcoin-datadir
option couldn't help.
This is more certain: specify whether we're testnet on every single query.
Now we can skip the attempt to parse bitcoin.conf, too.

This avoids us having to query it when we create anchor transaction, and
lets us always use dynamic fee information.
The config options for max and min are now percentages, rather than absolute.

getchaintips returns tips even if we don't have the body for them, so
we need to look for the active tip, not just the first (most-work) one.
Here's what happens in the log:

error message:

And here's an example problematic getchaintips output:

It's primitive, but we re-broadcast any txs not included in the main
chain every time the tip moves. We only track transactions we are
watching, but that turns out to cover every transaction we generate
anyway.

This can fail. Real cases include both sides dumping their commitment
txs in testing (only one can succeed).

Since any transaction with all segregated-witness inputs is non-malleable,
and all our transactions are that, we can remove normalized txids.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Like txids, we need to reverse them. We didn't, but then we only used them
to pass to/from bitcoind. We're about to get them from the block header,
so we need to fix that.

This lets us live in a segwit world, before segwit. It's a shim which we
can remove once we've changed all our outputs.
We need a few more sleeps in our test script, since we've slowed
things down by doing these calls for every tx in every block.

This can be used for proper support for fee negotiation; for the moment
it will be used for our anchor transaction creation.

This is only for the simple case where there are no HTLCs.
We group the current commit information together in the struct;
this involves a trivial transform from peer->cur_commit_theirsig to
peer->cur_commit.theirsig.

This is required for transactions which use OP_CSV to lock outputs for
a given amount of time: we need to know the mediantime of the block
they were included into.

bitcoind has a limit of 16 requests at once, by default, so our simplest
solution is to serialize them.

Because we use the bitcoin wallet to create the anchor transaction, we
need to make sure it doesn't broadcast it; safest to check their config
for the option.
