I had a routing problem, and wrote a simple unit test which passed. So
I wrote one which copied the failure case (and importantly, had a non-1
fee factor), which triggerd it.
In that real example, we underflowed which resulted in us not finding
a route. Simply don't consider routes which are infinite.

update-mocks was broken, since it assumed the daemon/ directory.
We now use "make" directly to build the test file and harvest errors,
and are more robust if it simply doesn't compile (ie. fails, but no
linker errors).

Since we initialize last_timestamp to 0, we ignore any initial update
with this timestamp. Don't compare it if we don't already have an
update, and don't initialize it, so valgrind can tell us if we use
it accidentally.

b'lightning_gossipd(3368): TRACE: Channel 6893:2:1(1) was updated.'
The same logic applies to node_updates, so we do the same there.

jl777 reported a crash when we try to pay past reserve. Fix that (and
a whole class of related bugs) and add tests.
In test_lightning.py I had to make non-async path for sendpay() non-threaded
to get the exception passed through for testing.
Closes: #236

You will want to 'make distclean' after this.
I also removed libsecp; we use the one in in libwally anyway.

Some fields were redundant, some are simply moved into 'struct lightningd'.
All routines updated to hand 'struct lightningd *ld' now.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

Other places require the flags and states, but the structure is
only needed in channeld, and even then we can remove several fields.

I was hoping to defer HTLC updates until we actually store HTLCs, but
we need to flush to DB whenever balances update as well.

The hmac_sha256() function got renamed to hmac_sha256_internal() in
9624a1a10e, but one obscure occasion
where it was used was missed and therefore it was still used with its
old name.

We're very simple about it: if there's a reorganization, we restart. Otherwise
we tell it about everything.

It's in the shachain, so storing it is completely redundant. We leave
it in for the moment so we can assert() that nothing has changed.

When loading from DB the list of htlcs was not being initialized which
caused a segfault when the first commit came around, this fixes it.

The peer->seed needs to be unique for each channel, since bitcoin
pubkeys and the shachain are generated from it. However we also need
to guarantee that the same seed is generated for a given channel every
time, e.g., upon a restart. The DB channel ID is guaranteed to be
unique, and will not change throughout the lifetime of a channel, so
we simply mix it in, instead of a separate increasing counter.
We also needed to make sure to store in the DB before deriving the
seed, in order to get an ID assigned by the DB.

This is the big one, and it's completely anticlimactic: it loads all
channels that have reached opening and are not marked as
closingd_complete into memory, that's it.

They happen to advance at the same pace but mixing them may have
unforeseen consequences, and I have done so a few times already so
this explicitly separates them.

This was supposed to be a temporary solution anyway, and I had a
rather annoying mixup between peer_id and unique_id, the latter of
which is actually a connection identifier.
Add the channel to the peer on the two open paths (fundee and funder)
and store it into the database. Currently fails when opening a channel
to a known peer after loading from DB because we attempt to insert a
new peer with the same node_id. Will fix later.
