The transparent passthrough that was recently introduced would end up
causing phantom quotes to appear around IDs when one of them was a
string. This happened for example when using `lightning-cli`, the code
would copy the quotes from the original request, insert our u64 ID,
and then re-add them on the way back as well.

check will actually do an RPC error, so if it doesn't, you know it's OK.
This would, of course, be in our man page if we had one :)

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.

I want to use param functions in plugins, and they don't have struct
command.
I had to use a special arg to param() for check to flag it as allowing
extra parameters, rather than adding a one-use accessor.

json_tok* is used with 'struct command', so rename this to match the other
low-level json tok helpers.

We simply look for the id token, and substitute it on the way in/out.
We also need to make sure output is '\n\n' terminated.
I started this because we weren't forwarding complex errors properly
(we treated them as a string), but it's also a huge simplification.
`struct plugin_rpc_request` is eliminated entirely: the information we need
is actually inside `struct command` already.

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).

Now we've updated ccan/pipecmd, we can use pipecmd_preserve to
preserve stderr for plugins so we see their error spew.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Note that this changes the order of arguments to pipecmd to match the
documentation, so we fix all the callers!
Also make configure re-run when configurator changes.

This currently just invokes GDB, but we could generalize it (though
pdb doesn't allow attaching to a running process, other python
debuggers seem to).

This tells the plugin both the `lightning-dir` as well as the
`rpc-filename` to use to talk to `lightningd`. Prior to this they'd
had to guess.

We inadvertently broke the compatibility between the python library
and the binary when switching to \n\n-delimiters. This reintroduces
the old inefficient parsing, and dynamically upgrades to the faster
version if it detects the \n\n-delimiter.

This is prep work for when we sign htlc txs with
SIGHASH_SINGLE|SIGHASH_ANYONECANPAY.
We still deal with raw signatures for the htlc txs at the moment, since
we send them like that across the wire, and changing that was simply too
painful (for the moment?).

We only use them for re-transmitting the last commitment tx,
and the HSM signs them sync so it's straight-line code.

We currently make sure that all the bitcoin_tx input scripts are NULL
and set the input script of the input we're signing, so we can easily
reuse the tx hashing code for signature checks. This means that we
sometimes jump through hoops to make sure input scripts are NULL, and
also means that the tx can't be const.
Put more logic inside bitcoin/tx so it can simply ignore things we
don't want to hash.

We currently hand the feature set from lightningd, but that's confusing
if they were ever different.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We currently generally assume the features we offer are fixed; this
makes the code clearer and handles where we offer features iff
EXPERIMENTAL_FEATURES=1

The check command allows us to check the parameters of a command
without running it. Example:
lightning-cli check invoice 234 foo desc
We do this by removing the "command_to_check" parameter and then using the
remaining parameters as-is.
I chose the parameter name "command_to_check" instead of just "command" because
it must be unique to all other parameter names for all other commands. Why?
Because it may be ambiguous in the case of a json object, where the parameters are
not necessary ordered. We don't know which one is the command to check and
which one is a parameter.

We can now set a flag to have param() ignore unexpected parameters.
Normally unexpected parameters are considered errors.
Needed by the check command.

Needed for check command. I left the print function in since it was so
convenient for debugging purposes.

Both of these plugins will fail in interesting ways, and we should
still handle them correctly.
