Rusty Russell e940d953bd fundchannel_start: We can't deprecate 'satoshi' here, since 'amount' wasn't sent
So we can't tell people they should use amount, until v0.8.2 is
released.  Another 6 months before we can deprecated the 'satoshi'
field here :(

Fixes: d149ba2f3a
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: JSON: `fundchannel_start` returns `amount` even when deprecated APIs are enabled.
Changelog-Deprecated: JSON: `fundchannel_start` `satoshi` field really deprecated now (use `amount`).

Rusty Russell 2aad3ffcf8 common: tal_dup_talarr() helper.
This is a common thing to do, so create a macro.

Unfortunately, it still needs the type arg, because the paramter may
be const, and the return cannot be, and C doesn't have a general
"(-const)" cast.

Vasil Dimov 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.

Rusty Russell 7a178ebb7a plugins: libplugin don't insist on 'jsonrpc' field from lightningd.
Spark does this, for example:

{"method":"pay","params":["lnbc..."],"id":22}

Which doesn't have a jsonrpc field.  The result is that the command
doesn't terminate, there is nothing in the logs, stderr contains
"pay: JSON-RPC message does not contain "jsonrpc" field", and
from then on "Unknown command 'pay'".

darosior 5840e90ceb plugins/libplugin: don't crash if 'lightning-rpc' doesnt exist (yet)
We are going to initialize a plugin before its creation, so log as
UNUSUAL instead.

Also, `pay` and `fundchannel` inits are using rpc_delve(), so we need to
io_new_conn() (which sets the socket as non blocking) after calling the
plugin's init.

This is also taken and adapted from lightningd/bitcoind.

make use of the result and the former can sometimes be slow (e.g. on
IBD).

darosior 70a79e3998 plugins/bcli: a new plugin for gathering Bitcoin data
Most is taken from lightningd/bitcoind and adapted. This currently
exposes 5 commands:
- `getchaininfo`, currently called at startup to check the network and
  whether we are on IBD.
- `getrawblockbyheight`, which basically does the `getblockhash` +
  `getblock` trick.
- `getfeerate`
- `sendrawtransaction`
- `getutxout`, used to gather infos about an output and currently used by
  `getfilteredblock` in `lightningd/bitcoind`.

As a separated commit because it was pre-existent (changelog + xfail test).

This also fix a logical problem in lightningd/plugin_control: we were

a 'dynamic' entry in its manifest to be dynamic, though it should have
been treated as static.

darosior 42cd23092c libplugin: use ccan/io for lightningd connections
Now we have streams and a global object, we can use them for io_plans.
This makes the logic closer from lightningd/plugin (it has been mostly
stolen from here), and simplifies the main.
This also allows plugins to use io_plans (thanks to the io_loop) for
asynchronous connections.

This commit only handle incoming commands.

darosior 3510c29e5d common: move json_stream helpers to common/json
Now that we have json_stream in common/, we can move all the related
helpers from lightningd/json to common/json. This way everyone can
benefit of them (including libplugin, the plugins themselves,
potentially lightning-cli), not lightningd alone!

Note that the Makefile of the common/test/ had to be modified, because
the new helpers make use of common/wireaddr... Which turns out to
\#include <lightingd/lightningd.h> ! So we couldnt just include the .c
and add mocks if we redefined some structs (hello run-param).

Wladimir J. van der Laan e4c6fd89b7 Add missing `extern` qualifiers for gcc 10
GCC 10 defaults to `-fno-common`. no longer automatically sharing
global variable definitions, which makes it important to define
them in only one place (otherwise there will be duplicate definition
errors). Add `extern` qualifiers where (I think) is the best place for
them.

Vasil Dimov 55173a56b7 Use dedicated type for error codes
Before this patch we used `int` for error codes. The problem with
`int` is that we try to pass it to/from wire and the size of `int` is
not defined by the standard. So a sender with 4-byte `int` would write
4 bytes to the wire and a receiver with 2-byte `int` (for example) would
read just 2 bytes from the wire.

To resolve this:

* Introduce an error code type with a known size:
  `typedef s32 errcode_t`.

* Change all error code macros to constants of type `errcode_t`.
  Constants also play better with gdb - it would visualize the name of
  the constant instead of the numeric value.

* Change all functions that take error codes to take the new type
  `errcode_t` instead of `int`.

* Introduce towire / fromwire functions to send / receive the newly added
  type `errcode_t` and use it instead of `towire_int()`.

In addition:

* Remove the now unneeded `towire_int()`.

* Replace a hardcoded error code `-2` with a new constant
  `INVOICE_EXPIRED_DURING_WAIT` (903).

Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2

You can create a no-bolt11 "sendpay" manually, but then you'll find it
