7d1137c45e bitcoind_sendrawtx: tie the sending of the transaction to the particular peer.
Not important just yet, but it will be soon.

cc9ffe6c40 bitcoind: allow callbacks which are tied to an object.
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.

b45b4eaba6 bitcoind: explicit flag to bitcoin-cli for testnet/regtest.
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.

02cb7abd9d bitcoind: keep running fee estimate.
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.

df4df8679d chaintopology: only report active chaintip.
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:

	+2849.963414597 lightningd(26779):BROKEN: bitcoin-cli getblock 0000000000000000018626ff7160bdf38a602e6650bd04ec258759ea578b106d false exited 91: 'error code: -32603
	error message:
	Can't read block from disk
	'

And here's an example problematic getchaintips output:

17167704a6 daemon: handle bitcoin transaction re-broadcasting.
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.

e60b1b4efa bitcoind: use correct endianness for block hashes.
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.

14d722d48d bitcoind: pretend normalized txids are in the block.
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.
