This will change the command `listconfigs` output in several ways:
- Deprecated the duplicated "plugin" JSON output by replacing it with
- a "plugins" array with substructures for each plugin with:
- path, name and their options
Changelog-Changed: JSON-RPC: `listconfigs` now structures plugins and include their options
Changelog-Deprecated: JSON-RPC: `listconfigs` duplicated "plugin" paths
Changelog-changed: .lightningd plugins and files moved into <network>/ subdir
Changelog-changed: WARNING: If you don't have a config file, you now may need to specify the network to lightning-cli

A log can have a default node_id, which can be overridden on a per-entry
basis. This changes the format of logging, so some tests need rework.

I was wondering why TAGS was missing some functions, and finally
tracked it down: PRINTF_FMT() confuses etags if it's at the start
of a function, and it ignores the rest of the file.
So we put PRINTF_FMT at the end, but that doesn't work for
*definitions*, only *declarations*. So we remove it from definitions
and add gratuitous declarations in the few static places.1

The fundchannel plugin needs to know how to build a transaction, so we need to
tell it which chainparams to use. Also adds `chainparams` as a global, since
that seems to be the way to do things in plugins.
This moves field initialization into plugins_new(), and
adds a memleak helper to search the request map:

Note that we move adding the plugin to the plugins list to the end, otherwise
the hook from logging can examine the (uninitialized) plugin.

This adds a new pair of files : lightningd/plugin_control, along with a new RPC
command : 'plugin'. This command can be used to manage plugins without restarting lightningd:
lightning-cli plugin start helloworld.py
lightning-cli plugin stop helloworld.py
This adds a 'configured' boolean member to the plugin struct so that we can add plugins to ld->plugins' list and differenciate fresh plugins.
This also adds 'plugins_start' so that new plugins can be started without calling 'plugins_init' and running an io loop
This is an old bug, where a plugin can get called while we're shutting
down (and have freed plugins), but it's triggered more reliably by the
new warning notification hook.
For good measure, we also make freeing a plugin self-delete.

Move it closer to ccan/json_out, in preparation for using that as a
replacement.
In particular:
1. Add a 'quote' field in json_add_member.
2. json_add_member now always escapes if 'quote' is true.
3. json_member_direct is exposed to allow avoiding of escaping.
4. json_add_hex can use this, so no longer needs to be in json_stream.c.
5. We don't make JSON manually, but always use helpers.
6. We now flush the stream (wake reader) only when we close it, or mark
command as pending.

- Related Changes for `warning` notification
Add a `bool` type parameter in `log_()` and `lov()`, this `bool` flag
indicates if we should call `warning` notifier.
1) The process of copying `log_book` of every peer to the `log_book` of
`ld` is usually included in `log_()` and `lov()`, and it may lead to
repeated `warning` notification. So a `bool`, which explicitly indicates
if the `warning` notification is disabled during this call, is necessary
.
2) The `LOG_INFO` and `LOG_DEBUG` level don't need to call
warning, so set that `bool` paramater as `FALSE` for these log level and
only set it as `TRUE` for `LOG_UNUAUSL`/`LOG_BROKEN`. As for `LOG_IO`,
it use `log_io()` to log, so we needn't think about notifier for it.
This was deeply surprising to me; there's a difference between a value not being
specified, and it being specified as "".

We store it in a strmap. This means we call the jsonrpc handler earlier,
so all callers need to call param() before they do anything else; only
json_listaddrs and json_help needed fixing.
Plugins still use '[usage]' for now.

This fixes a bug with a plugin duplicating an existing name
where we'd crash, too.
This doesn't work for builtins, which aren't tal objects, so
create a separate path for them.
