Substitute enable_rbf in TxBuilder with disable_rbf

[danielabrozzoni]

i.e., maybe all our txs should be RBF by default :)

Concept ACK, seems to be direction bitcoin core is going with bitcoin/bitcoin#25353. Even with all the controversy I think best practice from a general wallet point of view is to enable RBF so fees can easily be bumped when needed.

Since this is a breaking change we're going to hold off on this until 1.0 since that is a more obviously breaking release.

A small change but I think we should push to 2.0 milestone.

@notmandatory I would like to work on this, As far as I have understood I need to replace enable_rbf with disable_rbf in tx_builder.rs. This new function shouldn't initialize the value of rbf with some default value. Also, I assume I need to replace all instances of enable_rbf with disable_rbf.

@FlamingSaint hi sure go ahead and create a PR, there might also be some additional related changes, see discord discussion here: https://discord.com/channels/753336465005608961/753367451319926827/1228063458952478792

@FlamingSaint per your question on discord, yes you should use the same PR to make RBF the default for TxBuilder. So yes add disable_rbf() but since we still need a way to re-enable and enable RBF with a sequence, how about keeping the existing enable_rbf() and enable_rbf_with_sequence(RbfValue)?

Btw, let's keep the discussion here for people who don't use discord.

I'm picking up this issue, as it seems to have gone stale.
