We had a number of entry points into the HSM, all with different
behavior, so this is my attempt at unifying the way we handle
clients. Every client, except master, now takes the same path entry
point to the HSM and we use capability bit flags to indicate whether
the client is allowed to execute a set of operations.

The #389 introduced some changes that conflicted with
9de3827199 so this ports those changes
into #389 and fixes the `master` branch again.
Lesson learned: always rebase a PR before merging.

The same as master request/response: we queue up incoming replies we
don't want for later processing.

We revert to a simple select() loop. This makes things simpler, and fixes
the problem where we want to exit but we've partially read a peer packet.
We still queue up outgoing peer packets for non-blocking send: if we
went full sync there, we'd risk deadlock if both sides wrote a huge
number of packets and neither was reading.
This also greatly simplifies the next patches, where we want to make
our first get/response from gossipd.

The master now hands channeld either an error code, and channeld
generates the error message, or an error message relayed from another
node to pass through.
This doesn't fill in the channel_update yet: we need to wire up gossipd
to give us that.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Currently lightningd does this, but channeld is perfectly capable of doing it.
channeld is also in a far better position to add channel_updates to it.

The bulk of this patch is actually hoisting the get_shared_secret()
function (unchanged) so we can call it earlier.

If you run locally, it fails occasionally; presumably because it
sees previous funds. Use a random HSM key for that teste.

We can tell this more generically because the count of revocations
received != count of commitments sent. This is the correct condition
which allows us to restore the test we had to eliminate in
c3cb7f1c85.

Due to the large number of changes in phrasing, we'd have a large
number of CI builds failing. So just temporarily disable BOLT
checking.

As per the pending spec change: the other implementations use version 2,
and the current best practice advice (from maaku) is to use the latest
defined tx version.

The filter is being populated while initializing the daemon and by
adding new keys as they are being generated. The filter is then used
in connect_block to identify transactions of interest.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This is mainly used to filter for transactions that may be of interest
to us, i.e., whether one of our keys is the recipient. It currently
does onyl simple scriptpubkey checks, but will eventually be extended
to use bloomfilters and add more sophisticated checks.
For now the goal is to speed up the processing of blocks during startup.

I noticed some breakage with git master:
1. getinfo no longer supported (for us, use getblockchaininfo)
2. generate no longer supported (use generatetoaddress)
Both these options are supported at least in 0.15, too.

We weren't incrementing the `col` for the `local_shutdown_idx` field,
which meant that all following fields were incorrect. I removed the
`col` computation and opted for absolute indices instead, since they
are way less brittle. Just remember to add new fields to the query at
the end so we don't have to shift too often :-)

This addresses a performance regression introduced by
6ceb375650. We were storing it in an
otherwise empty DB transaction, which means that DB transaction was no
longer a no-op. Now we defer storing until we need to store the
corresponding HTLC anyway, so we can just piggyback on top of that
transaction.
This is also more consistent since we'd be forgetting the payment
anyway if we restart between adding the HTLC and committing to it.

This seems to happen when we manage to check between the
channel_announcement and the channel_update being processed.
