Rusty Russell 26dda57cc0 utils: make tal_arr_expand safer.
Christian and I both unwittingly used it in form:

	*tal_arr_expand(&x) = tal(x, ...)

Since '=' isn't a sequence point, the compiler can (and does!) cache
the value of x, handing it to tal *after* tal_arr_expand() moves it
due to tal_resize().

The new version is somewhat less convenient to use, but doesn't have
this problem, since the assignment is always evaluated after the
resize.

Rene Pickhardt 6b5db38774 pylightning: Made rpc a public member of Plugin and sorted imports
After this code change people can use `plugin.rpc` from anywhere in
their plugin code this is much nicer than going this way:

```
@plugin.method("init")
def init(options, configuration, plugin):
    global rpc
    basedir = plugin.lightning_dir
    rpc_filename = plugin.rpc_filename
    path = os.path.join(basedir, rpc_filename)
    rpc = LightningRpc(path)
```

or similarly that way:
```
@plugin.method("init")
def init(options, configuration, plugin):
    global rpc
    basedir = configuration['lightning-dir']
    rpc_filename = configuration['rpc-file']
    path = os.path.join(basedir, rpc_filename)
    rpc = LightningRpc(path)
```

Also the imports have been sorted alphabetically

Rusty Russell f5ced1ddd5 channeld: handle malformed onion properly.
When the next node tells us the onion is malformed, we now actually
report the failcode to lightningd (rather than generating an invalid
error as we do now).

We could generate the onion at this point, but except we don't know
the shared secret; we'd have to plumb that through from the incoming
channeld's HTLC.

Rusty Russell 554c3ec7e5 channeld: process onion packet ourselves.
This covers all the cases where an onion can be malformed; this means
we know in advance that it's bad.  That allows us to distinguish two
cases: where lightningd rejects the onion as bad, and where the next
peer rejects the next onion as bad.  Both of those (will) set failcode
to one of the BADONION values.

It's more natural than using a zero-secret when something goes wrong.

Also note that the HSM will actually kill the connection if the ECDH

We currently use 'all-zeroes' as 'unknown', but NULL is more natural

Christian Decker e0621fa8f7 pylightning: Better inject arguments in plugin method calls
If the `request` or `plugin` parameter that are injected by the
framework where before or inbetween positional arguments we'd be
injecting them incorrectly, i.e., we'd be providing them both as
`args` (and mismapping another argument) as well as `kwargs`.

This is a better way to map arguments, which takes advantage of the
fact that JSON-RPC calls are either all positional or named arguments.

I also included a test for various scenarios, that hopefull cover the
most common cases.

Rene Pickhardt 0321d79540 [plugin] Improved the example code to encourage usage of optional arguments (#2212)
The example code had the `plugin` argument as the last argument. this disallows arguments that have a standard value. As far as I understand the dispatching code the order of arguments does not matter since it is the name `plugin` that is relevant. Therefor I changed the order so that newbe's don't have to read the entire code and can easily add optional arguments
