@wythe points out we don't need to keep the around now param_is_set()
is removed. We can in fact go further and avoid marshalling them into
temporary objects at the caller altogether.
This means internally we have an array of struct param, rather than an
array of 'struct param *', which causes most of the noise in this
patch.

We're using a macro anyway, so appending "" make it a compile-time check.
Complicates testing a bit, since we actually use generated names there.

This is a bit more natural, IMHO. The only issue is that json_tok_tok is
special, so we end up with param_opt_tok() if you really want an optional
generic token.

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.
structeq() is too dangerous: if a structure has padding, it can fail
silently.
The new ccan/structeq instead provides a macro to define foo_eq(),
which does the right thing in case of padding (which none of our
structures currently have anyway).
Upgrade ccan, and use it everywhere. Except run-peer-wire.c, which
is only testing code and can use raw memcmp(): valgrind will tell us
if padding exists.
Interestingly, we still declared short_channel_id_eq, even though
we didn't define it any more!

We wrap it in 'struct pubkey' for typesafety and consistency, and the
next patch takes advantage of that when we move to pubkey_eq.

`getinfo` has been providing the blockheight for a good while and doesn't
require the `DEVELOPER=1` flag during compilation, so it should be the preferred
method to retrieve the blockchain height.
Implements an EWMA for the fee estimation. Achieves 90% influence of the newer
fee after 5 minutes, and adjusts to the polling rate that is configured.
Gossipd will ignore the second one, but doing it in the front end
gives an explicit error message.

Python dict can't have duplicate entries, but some options can be specified
multiple times. The easiest way is to put a list in the dict.

Only --addr implies announce-if-public: --bind-addr does not.
It's also possible to have --bind-addr to an automatic Tor address:
you'd have to dig the onion address out of the logs or getinfo to use
it, but it's possible.

And in debug.log:
2018-05-17T04:06:35Z Warning: Config setting for -rpcport only applied on regtest network when in [regtest] section.
Unfortunately, current versions including 0.16.1 *ignore* the contents of
a '[regtest]' section, so we need it in *both* places.
Also remove the misleading 'rpcport' initialization which we always
override.
Note that we don't fix this message though:
2018-05-17T04:06:35Z Config options rpcuser and rpcpassword will soon be deprecated. Locally-run instances may remove rpcuser to use cookie-based auth, or may be replaced with rpcauth. Please see share/rpcuser for rpcauth auth generation.

For some reason, we created a second bitcoin.conf in the regtest/ directory,
which AFAICT nothing uses.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
It's not optional for our test setup, and this makes it easier to invoke
bitcoin-cli manually, for example.
