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.
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.
Our previous param support was a bit limited in this case.
We create a dev- command multiplexer, so we can exercise it.

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!).

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.

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.

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.
