Rusty Russell f376a9c24c common: use tabs everywhere.
Didn't generally fixup inside comments and the bech32 code: reformatting that
is just anti-social.

lisa neigut f0f47ce153 warnings: if behind blockchain, don't show cannot afford
If you're replaying or syncing with the blockchain, show that error
instead of 'cannot afford', in the case of not having enough utxos
to pay for a transaction. This is the 'more correct' error to show, as
there's a chance that the funds you're expecting to spend are in the
portion of the blockchain that hasn't been synced yet.

Christian Decker 2ab56214ca json-rpc: Fix spacing issue in error report
There was a non-breakable space and a missing space in the error message for
missing utxo params.

lisa neigut 5c70890efa rpc: add 'utxos' parameter to txprepare + withdraw
Allow a user to select the utxo set that will be added to a
transaction, via the `utxos` parameter. Optional.

Format for utxos should be of the form ["txid:vout","..."]

darosior ac038b340b fundchannel: Add a new 'utxo' parameter
This new parameter takes a list of outpoints (as txid:vout) and fund a channel from the corresponding utxos.
Example : fundchannel <id> 10000 normal 1 [10767f0db0e568127fffd7f70a154d4599f42d62babf63230a7c3378bfce3cb0:0, c9e040e0b5fc8c59d5e7834108fbc5583001f414dd83faf0a05cff9d1a92d32c:0]

Rusty Russell 3b91a6f7c3 wtx_select_utxos: use wallet_tx as our allocation context for utxos.
We currently allocate utxos off cmd, but the next commit will persist a
wtx beyond the command which created it, breaking that assumption.

In general, a struct member should be owned by the struct itself, and
a tal context should be an explicit arg, not implicit.

Christian Decker 68fe5eacde wallet: Allow limiting the selection by confirmation height
This allows us to specify that an output must have been confirmed before the
given maximum height. This allows us to specify a minimum number of
confirmations for an output to be selected.

Rusty Russell 2632cc3f34 lightningd/json: make wallet_tx functions take amount_sat.
Using param_tok is generally deprecated, as it doesn't give any sanity checking
for the JSON 'check' command.  So make param_wtx usable directly, and
also make it have a struct amount_sat.

Rusty Russell d7e233e47d Move json and param core functionality into common, for plugins.
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.

Rusty Russell 71a40faae7 withdraw: fix incorrect error when we have an empty wallet.
This also highlights the danger of searching the logs: that error
appeared previously in the logs, so we didn't notice that the actual
withdraw call gave a different error.

Rusty Russell 52303029aa fundchannel: cap 'all' at 2^24-1 satoshi.
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.

Mark Beckwith 8f0ef1636f Added wallet related error codes
New codes: FUND_MAX_EXCEEDED, FUND_CANNOT_AFFORD, FUND_DUST_LIMIT_UNMET.

The error message "Cannot afford fee" was not exactly correct because
it would also occur if the amount requested could not be afforded.  So
I changed it to the more generic "Cannot afford transaction".

Other things:

* Fixed off-by-one satoshi in fundchannel manpage.
* Changed 'arror' to 'error' because we are not pirates.

Mark Beckwith 7f437715d5 Added error code parameter to command_fail
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).

Mark Beckwith 7767b68ee9 Removed redundancies in withdraw and fundchannel.
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.
