e81d78ec4c fundpsbt/utxopsbt: new min_witness_weight param
Needed for v2 of channel opens, where the minimum weight is 110; a
'simple utxo' (sig + key) weighs in at 107, so we a need a way to
establish a floor for this case.

Changelog-Added: JSON-RPC: fundpsbt/utxopsbt have new param, `min_witness_utxo`, which sets a floor for the weight calculation of an added input

b9ac032329 doc: force refresh of all manpages.
The idea is that you regenerate the man pages in the same commit you
alter them: that's how we know whether to try regenerating them or not
(git doesn't store timestamps, so it can't really tell).

Travis will now check this, so force them all to sync to this commit.

b07327a687 utxopsbt: new command to create PSBT from given utxos.
It's *possible* to do this using various RPC calls, but it's
unfriendly:

1. Call getinfo to get the current block height.
2. Call listfunds to map the UTXOs.
3. Create the PSBT and hope you get all the fields correct.

Instead, this presents an interface just like `fundpsbt`, with identical
returns.

I think it's different enough to justify a new command (though it
shares much internally, of course).

In particular, it's now quite simple to create a command which uses
specified utxos, and then adds more to meet any shortfall.

73a5f5b313 fundpsbt: make parameters more usable.
fundpsbt forces the caller to manually add their weight * feerate
to the satoshis they ask for.  That means no named feerates.

Instead, create a startweight parameter and do the calc for them
internally, and return the feerate we used (and, while we're at it,
the estimated final weight).

This API change is best done now, as it would otherwise have to
be appended as a parameter.
