This should provide the default help message and exit, but was
resulting in a segmentation fault from freeing pointers passed to
the default config.
Changelog-Fixed: lightning-cli properly returns help without argument
Clearly, listconfigs shouldn't list these.
Also, hoist the opt_hidden check since it's independent of whether
there's an arg or not.

Now we wire in the code which gathers configvars and parses from there;
lightningd keeps the array of configuration variables for future use.
Note that lightning-cli also needs to read the config, but it has its
own options (including short ones!) and doesn't want to use this
configvar mechanism, so we have a different API for that now.

These are gathered from the config files and the commandline, but the
process is rather complex! We want to remember where the options came
from in future (for a `setconfig` command), and also generalize
and simplify handling.

This adds:
1. ability to search for an option by name.
2. allowance to set our own bits when registering options.
3. show callbacks which can say "don't show", and variable length.

The top of the file indicates the following errors:
#define NO_ERROR 0
#define ERROR_FROM_LIGHTNINGD 1
#define ERROR_TALKING_TO_LIGHTNINGD 2
#define ERROR_USAGE 3
But we didn't use the right one for opt_parse failure, and didn't use the
correct constants everywhere.

We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.
Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

Procedure redefinition is a very cool feature but when other libraries redefine the same function can be very tricky to avoid compilation error.
This PR proposed a change of logic and use a customizzation function definition to read from the stdin, so we can avoid future error at compile time.
However, we could be check also the os or compiler that cause the error and redefine the missing function.
Changelog-None: Fixed compilation error due redefinition procedure.

connectd is going to end up using this do demux; make it fast and complete.
Fixing this reveals a problem in openingd: it now extracts the channel_id
from funding_signed (which is where we transition off the temporary), and
gets upset. So fix that.

If some parameter is malformed on the command line we could end up
with a malformed JSON-RPC request, which would then result in very
unhelpful error messages.
Fixes#4238
Changelog-Changed: cli: `lightning-cli` now performs better sanity checks on the JSON-RPC requests it sends.
We were masquerading errors when parsing the request by reporting only
a bogus malformed `id` field in the response, when the real issue was
that we were unable to parse the request in the first place (which
caused the null-id error to be returned).
Fixes#4238
This can be suppressed with -N.
Note that we wull get an error with older lightningd, but we ignore it
anyway.

Changelog-Added: cli: print notifications and progress bars if commands provide them.
Greatly simplify the changeset API. Instead of 'diff' we simply generate
the changes.
Also pulls up the 'next message' method, as at some point the
interactive tx protocol will be used for other things as well
(splices/closes etc)

We don't preserve detailed asset information at the moment, so provide a
way to convert from a sat to an amount_asset struct.
We also need a way to convert from an 'amount_asset' to a 'value' for
elements, which for explicit (i.e. non-blinded) asssets is a 0x01 prefix
plus the big-endian encoded value.
Our existing coin_moves tracking logic assumed that any tx we had an
input in belonged to *all* of our wallet (not a bad assumption as long
as there was no way to update a tx that spends our wallets)
Now that we've got `signpsbt` implemented, however, we need to be
careful about how we account for withdrawals. For now we do a best guess
at what the feerate is, and lump all of our spent outputs as a
'withdrawal' when it's impossible to disambiguate
Much nicer for grepping, since `{ "foo": { "bar": [7] } }` is turned into
`foo.bar[0]=7`.

Now that we have json_stream in common/, we can move all the related
helpers from lightningd/json to common/json. This way everyone can
benefit of them (including libplugin, the plugins themselves,
potentially lightning-cli), not lightningd alone!
Note that the Makefile of the common/test/ had to be modified, because
the new helpers make use of common/wireaddr... Which turns out to
\#include <lightingd/lightningd.h> ! So we couldnt just include the .c
and add mocks if we redefined some structs (hello run-param).
If absolute, we can deduce the lightning_dir, the network, and the
socket filename out of it.
This allows to be able to only specify the 'rpc-file', as before.
Changelog-Changed: Usage of `lightning-cli` by specifying only `--rpc-file` has been restored.
Changelog-changed: .lightningd plugins and files moved into <network>/ subdir

lightning-cli is going to need to know what network we're on, so
it will need to parse the config files. Move the code which does
the initial bootstrap parsing into common, as well as the config
file parsing core.

Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.
