If you're replaying or syncing with the blockchain, show that error
instead of 'cannot afford', in the case of not having enough utxos
to pay for a transaction. This is the 'more correct' error to show, as
there's a chance that the funds you're expecting to spend are in the
portion of the blockchain that hasn't been synced yet.
This is mainly an internal-only change, especially since we don't
offer any globalfeatures.
However, LND (as of next release) will offer global features, and also
expect option_static_remotekey to be a *global* feature. So we send
our (merged) feature bitset as both global and local in init, and fold
those bitsets together when we get an init msg.

By combining set_state() with selected_peer() we can give a single log
line describing what we're asking for, from whom.
We also add more verbosity to a few key areas, such as gossip rotation
and when gossipd tells a peer to send an error. And move a comment which
was above the wrong function (due to rebase?).

We often want a pointer which will turn to NULL if the pointed-to thing is
freed. This is possible with tal objects, so create it.

I have seen some strange flakiness (under VALGRIND), which I have
traced down to dev-disconnect "+" not working as expected. In
particular, the message is not sent out before closing the fd.
This seems to fix it on Linux, though it's so intermittant that it's hard
to be completely sure.

This patch adds a channel_id parameter to allow for specifying
channels that are lacking a short_channel_id.
Useful in the case where a peer has 1) multiple channels (ONCHAIN etc)
and 2) a channel where the funding transaction hasn't been
broadcast/mined.
According to the doc (https://download.libsodium.org/doc):
"sodium_init() initializes the library and should be called before
any other function provided by Sodium. [...]
the function ensures that the system's random number generator has
been properly seeded.".
Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

We now have a pointer to chainparams, that fails valgrind if we do anything
chain-specific before setting it.

Elements requires us to have an explicit fee output instead of bitcoin's
implied fee. We add the fee output mostly after sorting the other outputs
since that matches the behavior in elements itself.

Using a global variable is a bit lazy, but weaving the network type through
the entire stack is a daunting task. Maybe we can make that happen at a later
stage.
Most of the changes in `chainparams.c` are just formatting the
`genesis_blockhash` a bit nicer (`clang-format` to the rescue).

This encoding scheme is no longer just used for short_channel_ids, so make

I was seeing some accidental pruning under load / Travis, and in
particular we stopped accepting channel_updates because they were 103
seconds old. But making it too long makes the prune test untenable,
so restore a separate flag that this test can use.

It only had an effect if the peer didn't support option_gossip_queries, but
still, we don't want a gossip blast any more.

It's generally clearer to have simple hardcoded numbers with an
#if DEVELOPER around it, than apparent variables which aren't, really.
Interestingly, our pruning test was always kinda broken: we have to pass
two cycles, since l2 will refresh the channel once to avoid pruning.
Do the more obvious thing, and cut the network in half and check that
l1 and l3 time out.

There are some more #if DEVELOPER one-liners coming, this makes them

Allow a user to select the utxo set that will be added to a
transaction, via the `utxos` parameter. Optional.
Format for utxos should be of the form ["txid:vout","..."]

In this one, we always send my_current_per_commitment_point, though it's
ignored. And we have our official feature numbers.

The largest change is inside hsmd: it hands a null per-commitment key
to the wallet to tell it to spend the to_remote output.
It can also now resolve unknown commitments, even if it doesn't have a
possible_remote_per_commitment_point from the peer.
