4de11950ec lightningd: unify dynamic and static plugin initialization.
This means we now clean up options in startup plugins (that was only
done by dynamic code!), and now they both share the 60 second timeout
instead of 20 seconds for dynamic.

For the dynamic case though, it's 60 seconds to both complete
getmanifest and init, which seems fair.

0e20e3c5e7 df: rename 'funder' to 'opener'
Previously we've used the term 'funder' to refer to the peer
paying the fees for a transaction; v2 of openchannel will make
this no longer true. Instead we rename this to 'opener', or the
peer sending the 'open_channel' message, since this will be universally
true in a dual-funding world.

1dc281c111 pytest: test for pay adjacent routehint crash.
When route returns a result which is too expensive, we try to figure out which
hop is most expensive to exclude it for next time.

If it's a single-hop route, we don't count it, since the first hop is free.
That's not usually a problem, since single-hop routes can't exceed our limits
(they're always "free"!).

But if we are using a routehint, the total cost could exceed our limits,
even if the start of the routehint is a single hop away.

This reproduces that test case.

bf2a42ada5 channeld: defer first update_fee until we have an HTLC to send.
Sending update_fee immediately after channel establishment seems to
upset LND, so work around it by deferring it.  The reason we increase
the fee after establishment is because now we might need to close the
channel in a hurry due to htlcs, but until there are htlcs that's
unnecessary.

8370a627bb invoice: Parse amounts without a multiplier as BTC not msats
The spec states that invoices with an amount, but lacking a multiplier, should
be interpreted as integer Bitcoin amounts:

   `amount`: optional number in that currency, followed by an optional
   `multiplier` letter. The unit encoded here is the 'social' convention of a
   payment unit -- in the case of Bitcoin the unit is 'bitcoin' NOT satoshis.

b68066e8e8 python: Consolidate requirements.txt files in a single place
We had them split according the separate use-cases:

 - testing
 - doc-gen
 - wire-gen

But that was causing new contributors to miss some dependencies when they
first got hacking. So this consolidates all of our own dependencies in a root
requirements.txt, with the notable exception of `pyln-client`, `pyln-testing`
and `pyln-proto` which are distributed as PyPI modules and therefore have
their own dependencies that need to be tracked in the module root.

Closes #3518

158d2212c2 closingd: configurable closing fee negotiation step
When negotiating the transaction fee for closing a channel [1], we used
to always pick the middle of the range between our proposal and the
peer's proposal.

Introduce a new option `fee_negotiation_step` to the close command, so
the peer who initiates the close can choose his back off step.

Partially resolves https://github.com/ElementsProject/lightning/issues/3270
