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.

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.

This used to be a use-after-free bug in which we'd free the plugin and
then still have two connections that expect to be able to operate on
the plugin. This now signals the connections to exit and cleans up
once they do.

We can use the internal buffering of the json_stream instead of
manually building JSON-RPC calls. This makes it a lot easier to handle
these requests.
Notice that we do not flush concurrently and still buffer all the
things, but it avoids double-buffering things.

If the plugin fails to respond to we may end up hanging indefinitely,
so we limit the time we're willing to wait to 10 seconds.

I had this really contorted way of iterating over options that could
cause valgrind to choke. This is the much more intuitive way to
iterate.

The final step in the JSON-RPC passthrough: map the result we got from
the plugin back to the original request we got from the client.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This is needed in order to be able to add methods while initializing
the plugins, but before actually moving to the config dir and starting
to listen.

It wasn't JSON formatted either so there was no nice pretty-printing
way. This jsonifies and pretty prints it.

This is the `.clang-format` file I've been using for a while now. I
think that we might save on formatting nits if we tell new
contributors to use `clang-format`
We no longer use `dev-override-fees` to set the fees, rather we
instrument the `bitcoind` proxy to return the desired feerates.
