972432d285 param_feerate: parse numbers correctly.
If you used feerate=750, instead of feerate="750" it didn't work, since the
token is not a string.

Changelog-Fixed: JSON RPC: `withdraw` and `txprepare` `feerate` can be a JSON number.

73ad9b5c0a common: avoid locale dependent strtod(3)
Replace `json_to_double()` (which uses `strtod(3)`) with our own
floating-point parsing function `json_to_millionths()` that
specifically expects to receive such a number that can fit in a
64 bit integer after being multiplied by 1 million.

The main piece of the code in this patch comes from
https://github.com/ElementsProject/lightning/pull/3535#discussion_r381041419

89ceb273f5 wire: remove towire_double()
Before this patch we used to send `double`s over the wire by just
copying them. This is not portable because the internal represenation
of a `double` is implementation specific.

Instead of this, multiply any floating-point numbers that come from
the outside (e.g. JSONs) by 1 million and round them to integers when
handling them.

* Introduce a new param_millionths() that expects a floating-point
  number and returns it multipled by 1000000 as an integer.

* Replace param_double() and param_percent() with param_millionths()

* Previously the riskfactor would be allowed to be negative, which must
  have been unintentional. This patch changes that to require a
  non-negative number.

f7ebbb2ec5 common: make sphinx code ignorant of payload format.
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.

de6bf3e421 json: Add two param parsers for secrets and hex-encoded binary data
These are useful for the `createonion` JSON-RPC we're going to build next. The
secret is used for the optional `session_key` while the hex-encoded binary is
used for the `assocdata` field to which the onion commits. The latter does not
have a constant size, hence the raw binary conversion.

af4ffe5fcd dev-forget-channel: accept passing in channel_id
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.

220449e1cd ccan: import ccan/json_out and ccan/json_escape.
These are generalized from our internal implementations.

The main difference is that 'struct json_escaped' is now 'struct
json_escape', so we replace that immediately.

The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).

a25e22737c common/json_tok: add param_msat / param_sat.
The current param_sat accepts "any": rename and move that to invoice.c
where it's called.  We rename it to param_msat_or_any and invoice.c
is our first (trivial) amount_msat user.

bc41ab2cb9 param: make json_tok_ handlers all return command_result, rename to param_
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.

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.
