We previously registered hooks up in who-replies-to-getmanifest-first
order, but then if any had dependencies it would scatter that order.
This allows users to manually set dependencies developers have
forgotten by specifying the plugins manually in their configuration or
cmdline. This was an excellent consideration by @mschmook.

Now both python and c libraries are updated, we can officially
deprecate the old form.

Changelog-Deprecated: plugins: hooks should now be specified using objects, not raw names.
The next patch will use these to order the hooks.

Changelog-Added: plugins: hooks can now specify that they must be called 'before' or 'after' other plugins.
This adds a `state_change` 'cause' to a channel.
A 'cause' is some initial 'reason' a channel was created or closed by:
/* Anything other than the reasons below. Should not happen. */
REASON_UNKNOWN,
/* Unconscious internal reasons, e.g. dev fail of a channel. */
REASON_LOCAL,
/* The operator or a plugin opened or closed a channel by intention. */
REASON_USER,
/* The remote closed or funded a channel with us by intention. */
REASON_REMOTE,
/* E.g. We need to close a channel because of bad signatures and such. */
REASON_PROTOCOL,
/* A channel was closed onchain, while we were offline. */
/* Note: This is very likely a conscious remote decision. */
REASON_ONCHAIN
If a 'cause' is known and a subsequent state change is made with
`REASON_UNKNOWN` the preceding cause will be used as reason, since a lot
(all `REASON_UNKNOWN`) state changes are a subsequent consequences of a prior
cause: local, user, remote, protocol or onchain.

Just applied the same suppression as rusty in:
6635fe12e4 (Rusty Russell 2020-05-15 15:57:29 +0930 146)
/* 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.

This will allow nodes (with log-level=debug) to gather how many payments
are made without payment_secrets. We need to know this so we know when
we can make them compulsory.

1. One place returned false instead of -1.
2. The names implied it returned a bool, and it doesn't.
Fix both, and curse C's loose typing a little.

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.
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.
There's a spec rule about only ever sending a correctly sized
feature-bits, so as a precaution we have `clear_feature_bit` correctly
resize when a bit is cleared.
