Add the change output to owned_txfilter so its entry in db will
get a confirmation_height when detected in a block by filter_block_txs
before this commit, after a 'withdraw' command, 'listfunds' would
not show our change outputs as confirmed
Modified the log message in wallet_extract_owned_outputs to
append 'CONFIRMED' when it is called with a blockheight arg.
To make distinction between (1st call) when adding owned output to the
db and (2th call) when confirmed in block.
This causes a compiler warning if we don't do something with the
result (hopefully return immediately!).
We use was_pending() to ignore the result in the case where we
complete a command in a callback (thus really do want to ignore
the result).
This actually fixes one bug: we didn't return after command_fail
in json_getroute with a bad seed value.

Usually, this means they return 'command_param_failed()' if param()
fails, and changing 'command_success(); return;' to 'return
command_success()'.
Occasionally, it's more complex: there's a command_its_complicated()
for the case where we can't exactly determine what the status is,
but it should be considered a last resort.

Handers of a specific form are both designed to be used as callbacks
for param(), and also dispose of the command if something goes wrong.
Make them return the 'struct command_result *' from command_failed(),
or NULL.
Renaming them just makes sense: json_tok_XXX is used for non-command-freeing
parsers too.

json_escaped.[ch], param.[ch] and jsonrpc_errors.h move from lightningd/
to common/. Tests moved too.
We add a new 'common/json_tok.[ch]' for the common parameter parsing
routines which a plugin might want, taking them out of
lightningd/json.c (which now only contains the lightningd-specific
ones).
The rest is mainly fixing up includes.

This (will) avoid the plugin having to walk back from the params object
as it currently does.
No code changes; I removed UNUSED and UNNEEDED labels from the other
parameters though (as *every* json_rpc callback needs to call param()
these days, they're *always* used).

Such an API is required for when we stream it directly. Almost all our
handlers fit this pattern already, or nearly do.
We remove new_json_result() in favor of explicit json_stream_success()
and json_stream_fail(), but still allowing command_fail() if you just
want a simple all-in-one fail wrapper.

Now call param() even for commands that don't accept any parameters.
This is a bugfix of sorts. For example, before you could call:
bitcoin-cli getinfo blah
and the blah parameter would be ignored.
Now you will get an error: "too many parameters: got 1, expected 0"

And, reluctantly, default to bitcoind style.
"It's wrong to be right too soon."
Suggested-by: @cdecker
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We use feerate in several places, and each one really should react
differently when it's not available (such as when bitcoind is still
catching up):
1. For general fee-enforcement, we use the broadest possible limits.
2. For closingd, we use it as our opening negotiation point: just use half
the last tx feerate.
3. For onchaind, we can use the last tx feerate as a guide for our own txs;
it might be too high, but at least we know it was sufficient to be mined.
4. For withdraw and fund_channel, we can simply refuse.

This was a very simple change and allowed us to remove the special
`json_opt_tok` macro.
Moved the callback out of `common/json.c` to `lightningd/json.c` because the new
callbacks are dependent on `struct command` etc.
(I already started on `json_tok_number`)
My plan is to:
1. upgrade json_tok_X one a time, maybe a PR for each one.
2. When done, rename macros (i.e, remove "_tal").
3. Remove all vestiges of the old callbacks
4. Add new callbacks so that we no longer need json_tok_tok!
(e.g., json_tok_label, json_tok_str, json_tok_msat)

The easiest way to do this is to play with the 'wallet_tx' semantics
and have 'amount' have meaning even when 'all_funds' is set.
Note that we change the string 'Cannot afford funding transaction' to
'Cannot afford transaction' as this code is also used for withdrawls.

tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

The manpage did not specify the name of the named parameter (addresstype).
It does now.
Fixed manpage grammar errors.

Removed `json_get_params`.
Also added json_tok_percent and json_tok_newaddr. Probably should
have been a separate PR but it was so easy.

I crashed the HSMD, and it gave no output at all. That's because we
were only reading the status fd when we were waiting for a reply.
Fix this by using a separate request fd and status fd, which also means
that hsm_sync_read() is no longer required.

Until now, `command_fail()` reported an error code of -1 for all uses.
This PR adds an `int code` parameter to `command_fail()`, requiring the
caller to explicitly include the error code.
This is part of #1464.
The majority of the calls are used during parameter validation and
their error code is now JSONRPC2_INVALID_PARAMS.
The rest of the calls report an error code of LIGHTNINGD, which I defined to
-1 in `jsonrpc_errors.h`. The intention here is that as we improve our error
reporting, all occurenaces of LIGHTNINGD will go away and we can eventually
remove it.
I also converted calls to `command_fail_detailed()` that took a `NULL` `data`
parameter to use the new `command_fail()`.
The only difference from an end user perspecive is that bad input errors that
used to be -1 will now be -32602 (JSONRPC2_INVALID_PARAMS).
No new functionality, just a continuation of my work toward completing #665.
I removed the common members of `struct withdrawal` and `struct fund_channel`
and placed them in a new `struct wallet_tx`. Then it was fairly straightforward
to reimplement the existing code in terms of `wallet_tx`.
Since I made some structural changes I wanted to get this approved before I
go any farther.
Added 'all' to fundchannel help message.
* Modifies invoice command to have the following format
invoice <msatoshi> <label> <desc> <?expiry> <?fallbackaddr>
* Adds support for Segwit bcrt1 addresses for withdraw
* Add test case for fallback address in invoice creation
* Create a common json_tok_address_scriptpubkey to be used
by invoice and withdraw commands.
We always hand in "NULL" (which means use tal_len on the msg), except
for two places which do that manually for no good reason.

Now any struct channel is a genuine channel, the following fields are
always valid:
1. funding_txid: doesn't need to be a pointer.
2. our_msatoshi: doesn't need to be a pointer.
3. last_sig: doesn't need to be a pointer.
4. channel_info: doesn't need to be a pointer.
In addition, 'last_tx' is always valid.
The main effect is to remove a whole heap of branches from the wallet code.

Much like the database; peer contains id, address, channel contains
per-channel information. Where we create a channel, we always create
the peer too.
For the moment, peer->log and channel->log coexist side-by-side, to
reduce some of the churn.
Note that this changes the API to dev-forget-channel: if we have more
than one channel, we insist they specify the short-channel-id.

This caused a bit of confusion for our testers, when funding a channel
the funds are no longer available and listed in `lisfunds`, causing
them to believe funds to have disappeared. This PR adds funds that are
allocated to channels in the `listfunds` output, together with some
info about the channel, to make sure this doesn't happen again.

These are now logically arrays of pointers. This is much more natural,
