niftynei b44e36b99e spec-update: get rid of max-witness-len
We can use a fixed value and close the channel if they don't cover their

Rusty Russell 9b8f08a8a0 lightningd: return min-capacity-sat to its intended purpose.
And document exactly what it does: insist that an HTLC can pass of
this value (module assumptions of feerate).

Note that we remove the "is_opener" test from the capacity calculation
for anchor fees: it doesn't matter which side it is, someone has to pay
for anchor fees to it deducts from capacity.

This change breaks the test, which we rewrite.

Changelog-Changed: config: `min-capacity-sat` is now stricter about checking usable capacity of channels.

because it was actually the same format.

Previously we've used the term 'funder' to refer to the peer
