Christian Decker 5a55972f1a pytest: Have bitcoind own its proxies
We were restarting the with the nodes before, which was causing some
port contention. This is more natural since `bitcoind` will take care
of terminating all proxies it returned.

Christian Decker 5d05694920 json-rpc: Remove double-quoting on errors in JSON-RPC
The use of `json_tok_full_len` and `json_tok_full` in addition to
single quotes will result in double quoting, which is really weird. I
opted to single quoting using `'` instead which does not need to be
escaped.

Rusty Russell f8ecd08721 pay: don't list dummy channel if error is from final hop.
List the final one instead; if there's an error from the node it
may actually make sense to blame that channel (ie. previous node

Rusty Russell 4e6b8e13a4 lightningd/pay: simplify code significantly.
We no longer need a 'sendpay_result' structure, we can pass
appropriate parameter directly now they're simple calls.

Every waitsendpay command ends in tell_waiters_failed or
tell_waiters_success, which call sendpay_success or sendpay_fail on
all matching waiters.  These all return 'struct command_result *'.

In cases where the result is immediately known, we call
sendpay_success/sendpay_fail directly for the command.

This also adds a helpful 'failcodename' field to the JSON output.

[ This was four separate cleanup patches, but that contained much
redundancy and was even worse to review ]

Rusty Russell 1c58351551 lightningd: hardcode callbacks again.
With only one caller, we don't need a callback pointer any more; we can simply
call the function.

This required some code shuffling, and I changed the callback function
arguments to be in a more natural order, now they're not used as
callbacks.

Rusty Russell afab1f7b3c gossipd: handle onion errors internally.
As a general rule, lightningd shouldn't parse user packets.  We move the
parsing into gossipd, and have it respond only to permanent failures.

Note that we should *not* unconditionally remove a channel on
WIRE_INVALID_ONION_HMAC, as this can be triggered (and we do!) by
feeding sendpay a route with an incorrect pubkey.

Rusty Russell d69680934e short_channel_id: catch parsing errors.
I upgraded my node with --disable-compat, and a heap of channels closed like:

	CHANNELD_NORMAL:We disagree on short_channel_ids: I have 557653x0x1351, you say 557653x2373x1", 

This is because the scids are strings in the databases, and it failed to parse
them properly.

Now we'll not start if that happens.

lisa neigut c45d034bc0 option_data_loss_protect: fixup commitment point check
Spurious errors were occuring around checking the provided
current commitment point from the peer on reconnect when
option_data_loss_protect is enabled. The problem was that
we were using an inaccurate measure to screen for which
commitment point to compare the peer's provided one to.

This fixes the problem with screening, plus makes our
data_loss test a teensy bit more robust.

Rusty Russell 82ff580a66 json: add more efficient iterators for objects and arrays.
Christian points out that we can iterate by ->size rather than calling
json_next() to find the end (which traverses the entire object!).

Now ->size is reliable (since previous patch), this is OK.

Rusty Russell 7b59e26dd7 jsmn: upgrade so JSMN_OBJECT's size parameter is usable.
jsmn would accept invalid JSON objects.  This is bad because it would
set ->size incorrectly: we expect to have at least size * 2 tokens (in
pairs).  We want to rely on ->size, but this would create an exploitable
buffer overflow!

Fortunately, this is fixed upstream, so we add a test and upgrade to v1.0.0.

Rusty Russell 774973263c common/test/run-json: check tok->size is as expected.
The external/jsmn/README.md only says:
		int size;        // Number of child (nested) tokens

But it only counts *direct* children, or *direct* members for an object.

This test verifies this (the bug proved to be elsewhere: see next patch!).

Rusty Russell ad1e1bd528 plugins: minimal 'pay' plugin.
I wrote this sync first, then rewrote async, then developed libplugin.
But committing all that just wastes reviewer time, so I present it as
if it was always asnc and using the library helper.

Currently the command it registers is 'pay2', but when it's complete
we'll remove the internal 'pay' and rename it. This does a single
'getroute/sendpay' call.  No retries, no options.

Shockingly, this by itself is almost sufficient to pass our current test
suite with `pay`->`pay2`.
