We also make `--help` a non-early arg so it allows for the plugins to
register their options before printing the help message. The options
themselves are stored in a separate struct inbetween them being
registered and them being forwarded to the plugin. Currently only
supports string options.

The idea is that `plugin` is an early arg that is parsed (from command
line or the config file). We can then start the plugins and have them
tell us about the options they'd like to add to the mix, before we
actually parse them.

Such an API is required for when we stream it directly. Almost all our
handlers fit this pattern already, or nearly do.
We remove new_json_result() in favor of explicit json_stream_success()
and json_stream_fail(), but still allowing command_fail() if you just
want a simple all-in-one fail wrapper.

We initialize it to 30 seconds, but it's *always* overridden by the
gossip_init message (and usually to 60 seconds, so it's doubly
misleading).

Right now, the `config` file is read *after* the configuration working directory is moved to in the software. However one configuration option `lightning-dir` settable in the `config` file sets this working directory. As the directory is already opened (which defaults to `$HOME/.lightning`) before the configuration is read, the configured directory will not be used.
This patch parses the configuration file before opening the working directory, fixing this bug.

We do this a lot, and had boutique helpers in various places. So add
a more generic one; for convenience it returns a pointer to the new
end element.
I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.

Manipulate fees via fake-bitcoin-cli. It's not quite the same, as
these are pre-smoothing, so we need a restart to override that where
we really need an exact change. Or we can wait until it reaches a
certain value in cases we don't care about exact amounts.

This was a very simple change and allowed us to remove the special
`json_opt_tok` macro.
Moved the callback out of `common/json.c` to `lightningd/json.c` because the new
callbacks are dependent on `struct command` etc.
(I already started on `json_tok_number`)
My plan is to:
1. upgrade json_tok_X one a time, maybe a PR for each one.
2. When done, rename macros (i.e, remove "_tal").
3. Remove all vestiges of the old callbacks
4. Add new callbacks so that we no longer need json_tok_tok!
(e.g., json_tok_label, json_tok_str, json_tok_msat)

This gives the network options a chance to load from arguments before usage
exits, so that the proper defaults are shown.
This didn't work:
lightningd --mainnet --help
before it showed testnet defaults, now it shows mainnet defaults.

In several places we use low-level tal functions because we want the
label to be something other than the default. ccan/tal is adding
tal_*_label so replace them and shim it for now.

tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

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.

During a meeting earlier this week we agreed with Eclair to temporarily
increase the final CLTV delta in our invoices to establish
compatibility with the already deployed Eclair wallets. They in turn
agreed to remove the enforcement of higher final CLTV deltas, or bump
it locally should it not match their expectations as allowed by
BOLT 11. This has since been implemented in ACINQ/eclair#627.
The fee range can sometimes cause channels to be closed when the estimator
jumps. This has been the case a few times in the last months, and causes a
number of channels to be closed, and issue reports to be filed.
Increasing this from 5x to 10x should get rid of 84%+ of these
closures (measured based on 1h windows over the last 6 months and assuming
worst case situations).

Until now, `command_fail()` reported an error code of -1 for all uses.
This PR adds an `int code` parameter to `command_fail()`, requiring the
caller to explicitly include the error code.
This is part of #1464.
The majority of the calls are used during parameter validation and
their error code is now JSONRPC2_INVALID_PARAMS.
The rest of the calls report an error code of LIGHTNINGD, which I defined to
-1 in `jsonrpc_errors.h`. The intention here is that as we improve our error
reporting, all occurenaces of LIGHTNINGD will go away and we can eventually
remove it.
I also converted calls to `command_fail_detailed()` that took a `NULL` `data`
parameter to use the new `command_fail()`.
The only difference from an end user perspecive is that bad input errors that
used to be -1 will now be -32602 (JSONRPC2_INVALID_PARAMS).
Because we have too many which are never used and I don't want to document
them.
1. Remove unused anchor_onchain_wait. When implemented, it should be
hardcoded to 100 or more.
2. Remove anchor_confirms_max. 10 always reasonable, and we can readd
an override option should someone need it.
3. max_htlc_expiry should be the same as locktime_max (which increases
from 3 to 5 days by default): they're both a limit on how long
funds can be locked up.
4. channel_update_interval should always be a dev option.

Make --override-fee-rates a dev option. We use default-fee-rate in
its place, which (since bitcoind won't give fee estimates in regtest
mode for short chains) gives an effective feerate of 15000/7500/3750.

Tor wasn't actually working for me to connect to anything, but it worked
for 'ssh -D' testing.
Note that the resulting 'netaddr' is a bit weird, but I guess it's honest.

This is useful for the next patch, where we want to hand the unresolved
name through to the proxy.
This also addresses @Saibato's worry that we still called getaddrinfo()
(with the AI_NUMERICHOST option) even if we didn't want a lookup.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This means it will effect connect commands too (though it's too
late to stop DNS lookups caused by commandline options).
We also warn that this is one case where we allow forcing through Tor
without a proxy set: it just means all connections will fail.
