Rusty Russell 64ab7c0c1d lightningd: add --developer runtime option.
Currently it just defaults to the DEVELOPER compile option, but we'll
move over to this.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: Config: `--developer` enables developer options and changes default to be "disable deprecated APIs".

Alex Myers bd4a001279 cli: don't crash when there's no argument
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

Rusty Russell 0c4426a349 lightningd: remove deprecated_apis global, put into lightningd.
We usually have access to `ld`, so avoid the global.

The only place generic code needs it is for the json command struct,
and that already has accessors: add one for libplugin and lightningd
to tell it if deprecated apis are OK.

Rusty Russell 8281008b08 lightningd: annotate configuration settings which contain JSON literals.
We have hacky code to show some listconfigs values as literals; instead
explicitly encode the types.

Rusty Russell edbaa944da lightningd: switch parsing to common/configvar
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.

Rusty Russell 36200a6593 common/configvar: routines to manage config settings.
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.

Rusty Russell f7df7eeb42 lightningd: implement more show commands to reduce listconfigs special casing.
Note that this actually changes listconfigs output for three msat
fields, which were not changed with the great msat merge.  Since
listconfigs isn't actually used by grpc, and the values are always a
little vague, I simply changed this.

Changelog-Fixed: JSON-RPC: `listconfigs` `htlc-minimum-msat`, `htlc-maximum-msat` and `max-dust-htlc-exposure-msat` fields are now numbers, not strings.

Rusty Russell f45c17450b ccan: update to latest ccan/opt
This adds:

2. allowance to set our own bits when registering options.
3. show callbacks which can say "don't show", and variable length.

Rusty Russell 4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.
