Removed `json_get_params`.
Also added json_tok_percent and json_tok_newaddr. Probably should
have been a separate PR but it was so easy.

This is part of #1464 and incorporates Rusty's suggested updates from #1569.
See comment in param.h for description, here's the basics:
unsigned cltv;
const jsmntok_t *note;
u64 msatoshi;
struct param * mp;
if (!param_parse(cmd, buffer, tokens,
param_req("cltv", json_tok_number, &cltv),
param_opt("note", json_tok_tok, ¬e),
mp = param_opt("msatoshi", json_tok_u64, &msatoshi),
NULL))
return;
if (param_is_set(mp))
do_something()
There is a lot of developer mode code to make sure we don't make mistakes,
like trying to unmarshal into the same variable twice or adding a required param
after optional.
During testing, I found a bug (of sorts) in the current system. It allows you
to provide two named parameters with the same name without error; e.g.:
# cli/lightning-cli -k newaddr addresstype=p2sh-segwit addresstype=bech32
{
"address": "2N3r6fT65PhfhE1mcMS6TtcdaEurud6M7pA"
}
It just takes the first and ignores the second. The new system reports this as an
error for now. We can always change this later.
We move it into jsonrpc where it belongs, and make it fail the command.
This means it can tell us exactly what was wrong.

In future it will have TOR support, so the name will be awkward.
We collect the to/fromwire functions in common/wireaddr.c, and the
parsing functions in lightningd/netaddress.c.

You will want to 'make distclean' after this.
I also removed libsecp; we use the one in in libwally anyway.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

The new onion uses the `channel_id` instead of the `node_id` of the
next hop to identify where to forward the payment. So we return the
exact channel chosen by the routing algo, to avoid having to look it
up again later.
We need some way to reflect the tradeoff between the possible delay if
a payment gets stuck, and the fees charged by nodes. This adds a risk
factor which reflects the probability that a node goes down, and the
cost associated with losing access to our funds for a given time.

This is less convenient to use, but makes far more sense for a real
user (like a wallet). It can ask about the route, then decide whether
to use it or not.
This will make even more sense once we add a parameter to control how
long we let the HTLC be delayed for, so a client can query for high,
medium and low tolerances and compare results.
