This increments the `data_version` upon committing dirty transactions, reads
the last data_version upon startup, and tracks the number in memory in
parallel to the DB (see next commit for rationale).
Changelog-Changed: JSON-RPC: Added a `data_version` field to the `db_write` hook which returns a numeric transaction counter.
This is the final step: we pass the complete fee_states to and from
channeld.
Changelog-Fixed: "Bad commitment signature" closing channels when we sent back-to-back update_fee messages across multiple reconnects.

The invoice_try_pay code now takes a set, rather than a single htlc, but
it's basically the same thing.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is a transient field, so rework things so we don't leave it in
struct htlc_out. Instead, load htlc_in first and connect htlc_out to
them as we go.
This also changes one place where we use it instead of the am_origin
flag.

Now "raw_payload" is always the complete string (including realm or length
bytes at the front).
This has several effects:
1. We can receive an decrypt an onion which is grossly malformed.
2. We can still hand this to the htlc_accepted hook.
3. We then fail it unless the htlc_accepted accepts it manually.
4. The createonion API now takes the raw payload, and does not know
anything about "style".
The only caveat is that the sphinx code needs to know the payload
length: we have a call for that, which simply tells it to copy the
entire onion (and treat us as the final node) if it's invalid.

We don't set the secret to compulsory (yet!) but put code in for the
future. Meanwhile, if there is a secret, check it is correct.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
In a future version, we will use features to insist that payers
provide the secret. In transition, we may have old invoices which
didn't insist on that, so we need to know this on a per-invoice basis.
Not sure if I got the right syntax for adding an empty blob though!

We have consolidated the two functions into a single `route_step_decode`
function, and made it static since we call it in the `process_onionpacket`
function. We remove the two exposed functions since they're no longer useful.
Since the parser itself just parses and doesn't include validation anymore we
need to put that functionality somewhere. The validation consists of enforcing
that the types are in monotonically increasing order without duplicates and
that for the even types we know how to handle it.
This allows finegrained logging control of particular subdaemons or
subsystems.
To do this, we defer setting the logging levels for each log object
until after early argument parsing (since e.g. "bitcoind" log object
is created early).

Changelog-changed: Options: log-level can now specify different levels for different subsystems.
1. Printed form is always "[<nodeid>-]<prefix>: <string>"
2. "jcon fd %i" becomes "jsonrpc #%i".
3. "jsonrpc" log is only used once, and is removed.
4. "database" log prefix is use for db accesses.
5. "lightningd(%i)" becomes simply "lightningd" without the pid.
6. The "lightningd_" prefix is stripped from subd log prefixes, and pid removed.

Changelog-changed: Logging: formatting made uniform: [NODEID-]SUBSYSTEM: MESSAGE
Changelog-removed: `lightning_` prefixes removed from subdaemon names, including in listpeers `owner` field.
We had a separate logbook for each peer, and copy log entries above
the printable log level into the master logbook. This didn't always
work well, since we didn't dump it on crash for example.
Keep a single global logbook instead, and remove this infrastructure.

A log can have a default node_id, which can be overridden on a per-entry
basis. This changes the format of logging, so some tests need rework.

I had a report of a 0.7.2 user whose node hadn't appeared on 1ml. Their
node_announcement wasn't visible to my node, either.
I suspect this is a consequence of recent version reducing the amount of
gossip they send, as well as large nodes increasingly turning off gossip
altogether from some peers (as we do). We should ignore timestamp filters
for our own channels: the easiest way to do this is to push them out
directly from gossipd (other messages are sent via the store).
We change channeld to wrap the local channel_announcements: previously
we just handed it to gossipd as for any other gossip message we received
from our peer. Now gossipd knows to push it out, as it's local.
This interferes with the logic in tests/test_misc.py::test_htlc_send_timeout
which expects the node_announcement message last, so we generalize
that too.

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.

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.
Command format: close id [unilateraltimeout] [destination]
Close the channel with peer {id}, forcing a unilateral
close after {unilateraltimeout} seconds if non-zero, and
the to-local output will be sent to {destination}. If
{destination} isn't specified, the default is the address
of lightningd.
Also change the pylightning:
update the `close` API to support `destination` parameter
`shutdown_scriptpubkey[REMOTE]` is original remote_shutdown_scriptpubkey;
`shutdown_scriptpubkey[LOCAL]` is the script used for "to-local" output when `close`. Add the default is generated form `final_key_idx`;
Store `shutdown_scriptpubkey[LOCAL]` into wallet;
With enable-autotor-v2 defined in cmdline the default behavior to create
v3 onions with the tor service call, is set to v2 onions.

We used to do some of the setup work in db.c, which is now free of any
sqlite3-specific code. In addition we also switch over to fully qualified DSNs
to specify the location of the wallet.

Rather than reaching into data structures, let them register their own
callbacks. This avoids us having to expose "memleak_remove_xxx"
functions, and call them manually.
Under the hood, this is done by having a specially-named tal child of
the thing we want to assist, containing the callback.

This has a slight side-effect of removing the actual begin and commit
statements from the `db_write` hooks, but they are mostly redundant anyway (no
harm in grouping pre-init statements into one transaction, and we know that
each post-init call is supposed to be wrapped anyway).

We want to still allow incoming connections, and reestablishment of
channels, but if one tries to give us an HTLC, stall until we're
synced.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
`close` takes two optional arguments: `force` and `timeout`.
`timeout` doesn't timeout the close (there's no way to do that), just
the JSON call. `force` (default `false`) if set, means we unilaterally
close at the timeout, instead of just failing.
Timing out JSON calls is generally deprecated: that's the job of the
client. And the semantics of this are confusing, even to me! A
better API is a timeout which, if non-zero, is the time at which we
give up and unilaterally close.
The transition code is awkward, but we'll manage for the three
releases until we can remove it.
The new defaults are to unilaterally close after 48 hours.
