b7a56f0531 plugin: Gate the plugin subsystem with the --enable-plugins configure flag
Since we are planning to release a bug fix release, and the plugin
subsystem is not yet complete, it is better to make plugin support
opt-in while we continue testing.

Fortunately, we can calculate the sha256 ourselves, so the
outgoing channeld doesn't need to tell us.

8f8783c0e3 pay: correctly blame the *next* node on BADONION error.
The node which sent the error is doing so because the following
one sent WIRE_UPDATE_FAIL_MALFORMED_HTLC.

554c3ec7e5 channeld: process onion packet ourselves.
This covers all the cases where an onion can be malformed; this means
we know in advance that it's bad.  That allows us to distinguish two
cases: where lightningd rejects the onion as bad, and where the next
peer rejects the next onion as bad.  Both of those (will) set failcode
to one of the BADONION values.

7e01efbd1f lightningd: clean up htlc_in->shared_secret to be optional.
We currently use 'all-zeroes' as 'unknown', but NULL is more natural
even if we have to send it as all-zeroes over the wire due to
expressiveness limitations in our generation code.

26484b8aa5 memdump: rearrange order to avoid command_its_complicated().
memdump iterates through the various daemons asking them to check for
leaks.

We currently call openingds (there might be none), channelds (there
might be none), then hsmd synchronously (the other daemons).  If hsmd
reports a leak, we'll fail the dev-memleak command immediately.

Change the order to call connectd first; that's always async, so we
can happily mark the command still pending.

819078fe18 param: make command_fail/command_success WARN_UNUSED_RESULT.
This causes a compiler warning if we don't do something with the
result (hopefully return immediately!).

We use was_pending() to ignore the result in the case where we
complete a command in a callback (thus really do want to ignore
the result).

This actually fixes one bug: we didn't return after command_fail
in json_getroute with a bad seed value.

68bb36b210 json-rpc: make commands return 'struct command_result *'.
Usually, this means they return 'command_param_failed()' if param()
fails, and changing 'command_success(); return;' to 'return
command_success()'.

Occasionally, it's more complex: there's a command_its_complicated()
for the case where we can't exactly determine what the status is,
but it should be considered a last resort.

bc41ab2cb9 param: make json_tok_ handlers all return command_result, rename to param_
Handers of a specific form are both designed to be used as callbacks
for param(), and also dispose of the command if something goes wrong.

Make them return the 'struct command_result *' from command_failed(),
or NULL.  

Renaming them just makes sense: json_tok_XXX is used for non-command-freeing
parsers too.

93bf7c4839 param: make command sinks (fail/success) return a special type.
These routines free the 'struct command': a common coding error is not
to return immediately.

To catch this, we make them return a non-NULL 'struct command_result
*', and we're going to make the command handlers return the same (to
encourage 'return command_fail(...)'-style usage).

We also provide two sources for external use:
1. command_param_failed() when param() fails.
2. command_its_complicated() for some complex cases.

968aeac908 plugin: Set LIGHTNINGD_PLUGIN env var inform plugins
It might be useful to take special precautions inside a plugin when

var is just set so plugins can differentiate correctly. I don't unset

itself.

The transparent passthrough that was recently introduced would end up
causing phantom quotes to appear around IDs when one of them was a

d7e233e47d Move json and param core functionality into common, for plugins.
json_escaped.[ch], param.[ch] and jsonrpc_errors.h move from lightningd/

We add a new 'common/json_tok.[ch]' for the common parameter parsing
routines which a plugin might want, taking them out of
lightningd/json.c (which now only contains the lightningd-specific
ones).

The rest is mainly fixing up includes.
