5e6b0f9445 lightningd: fix crash if we abort after enabling notifications.
The rpc_command hook means that we have a delay between receiving
a JSON command and actually calling the handler.  In this case, the
caller can go away:

/* cppcheck-suppress uninitvar - false positive on f1->bits */

My cppcheck was complaining about the same issue in the following functions.
I wonder why travis does not care though.

4ea9d9e928 df: Pass new feerate options through to plugin, set reasonable bounds
We let the plugin decide what feerate to accept/whether or not to add
funds to the open. To aid this decision, we also send the plugin what we
(c-lightning) currently have as our max and min acceptable feerates.

We also now use these as our default for max/min acceptable feerate
range when sending an openchannel offer to a peer.

In the future, it might be a good idea to make these more easily
changeable, either via a config setting (?) or a command param.

21122af3a8 dev-force-features: adds a second valid format for forcing features
The previous dev-force-features forced you to explicitly declare every
desired feature bit in an array, for each set.

Here, we allow you to also denote adding/subtracing a feature bit
by just passing in the number of the bit to flip and the direction to
turn it. e.g.

	'dev-force-features': '+223'

Will turn on opt_dual_fund/odd.

	'dev-force-features': '-16'

Will flag off opt_basic_mpp.
