WIP: Add support for Bitcoin Core v28

[tnull]

Based on #21.

Currently still work in progress (as v28.0rc1 has just been released, so no final binaries are available etc).

Thanks for working on this man. Can you pull the formatting changes out please, I was surprised to see changes to the json/src/v17 files. Also, did you get the contents of rpc-ap.txt from running bitcoin-cli help against a Core v28 instance or did you copy'paste for another existing file? (EDIT: Oh submitpackage only exists in v28 so you must have used bitcoin-cli :)

I merged #22 so you can rebase when you feel like it. Cheers

Ah, now dropped them, didn't realize they slipped in as I didn't expect it either.

Jup, run bitcoin-cli (took me a while to get where rpc-api.txts are coming from though :)

Cool, rebased for now, will resume work ~end of this week.

Ha! So we need a "How to add support for a new version" doc. I'd love a script to check that all the rpc-ap.txt files actually come from bitcoin-cli help > rpc-api.txt for the correct version of Core and are not just copied from another file. Yesterday I was looking at the wrong buffer in my editor and thought I'd made a mistake so went back and checked manually. It would be nice to check that the mod.rs rustdoc is using the correct rpc-api.txt content as well, as it is we just have to hope I didn't get mixed up :)
