This is just taking the existing serialization code and repackaging it in a
more useful form.

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 'plugin_unregister_hook' and 'plugin_unregister_hook_all'
functions to unregister a given hook a plugin registered, or all hooks a
plugin registered for. Since hooks can only be registered once, it's
useful in the case a new plugin is added which would be prefered for
hook registration over an already loaded plugin.
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
It assumes the head of the array is the object/array we want to remove from,
but that's not true if we're trying to remove from a sub-object.

No code changes, just move.
Put all the dev options into the one function, and register (and
comment on) the early args first.

I noticed that --network=regtest didn't override 'network=bitcoin' in
the config file.
Normally we parse the config file first, then the commandline (so the cmdline
wins). But for early options, we do cmdline first so we can find the config
file. That was fine when the only early option was the location of the
config file, but now it includes plugins and the network setting.
So do a boutique cmdline parse *just* to find the config file, then parse
the config file early options, then the cmdline early options.

At the moment we simply get a crypto log line on exit:

The spec says to close the channel if they send us an error, but we
need to be more lenient to preserve channels with other
implementations.

We normally reconnect after 1 second: have a flag to say wait for
60. This will be used in the next patch which handles "soft" errors.

Header from folded patch 'channel_fail_transient_slowretry.patch':
fixup! lightningd: add slow_reconnect flag for transient failure.
@ZmnSCPxj points out that function is unsafe, since omitting the bool
parameter still compiled. Make it two separate functions, each
with a distinctive name so every caller has to be fixed.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
There's only one caller which used the flag.
As a side-effect, now we'll try reconnect even if the previous owner
was NULL (which mainly effects the case where we couldn't create the subd).

I mean, we still crash, but we give an error now :)

Our previous param support was a bit limited in this case.
We create a dev- command multiplexer, so we can exercise it.

updates the bolt version to 6639cef095a2ecc7b8f0c48c6e7f2f906fbfbc58.
this requires us to use the new bolt parser at generate-bolt.py
and updates to all of the type specifications (ie. from u8 -> byte)
test_funding_cancel_race explicitly attempts to trigger this via a race
condition; this conflicts with our post-test checks that no broken
logs were logged. as a middle ground, we log it as unusual, not broken,
as it's possible for it to attempt to fail if it was begun at the same
time as the complete is.
It probably doesn't matter to "fundchannel_cancel" exactly why the
fundchannel didn't work (though it can read the error msg), and we
should always fail any pending fundchannel_complete command.

Instead of taking over the ->cmd pointer, append ourselves to a list
of cancels. This fixes the test_funding_cancel_race.

At the beginning of the lightningd, we use "echo" command to check if bitcoin-cli is running.
Now we raplace "echo" with "getblockchaininfo" for this check, and also check whether the "chain" field in response is same as the blockchain that lightningd is on.
"getblockchaininfo" is also valid for litecoin-cli.
1. bcli_args_direct() will be used in wait_for_bitcoind;
At the beginning, we check if bitcoin-cli is running by "echo" command
whitout any bitcoin_cli struction. If this first command fails, we need
present the agrs gathered, like "-rpcuser", like "-rpcpassword".
Related changes include:
i) rename bcli_args() to bcli_args_direct(), and use 'const char **'
as the paramater for bcli_args_direct();
ii) add a new function bcli_args() warpped on bcli_args_direct(), this
warpping can reduce the large number of changes later in the file;
2. bcli_args() warpping on bcli_args_direct() is used like original.
And clean up some dev ones which actually happen (mainly by calling
channel_fail_permanent which logs UNUSUAL, rather than
channel_internal_error which logs BROKEN).

Since we now have a couple of long-lived dependents it is time we stop
removing channels from the table once they are fully closed, and instead just
mark them as closed. This allows us to keep forwards and transactions foreign
keys intact, and it may help us debug things after the fact.
