Subject: [PATCH 1/7] Remove usages of onNeighborChange

Oh. This is from ye olde days (it's one of the first PRs to CC[^1]!). In
pre-1.13 days, furnaces changing their lit state would replace the block
(creating a new BE) and then set back the old BE. CC wouldn't pick up
the second event, and so would continue to use the peripheral from the
first.

We don't really need this any more, for a couple of reasons:
 a) Furnaces don't do this any more.

 b) Peripherals are now refreshed on the next tick rather than
    immediately.

 c) Forge's capabilities have an explicit invalidate() hook already. This
    technically only detects *removing* block entities, but I'm not sure
    there's any cases where you add a block entity without also
    triggering a block state change.

Ironically, the place we probably need this more is Fabric, where the
lookup API doesn't have a public invalidate hook (it's hidden away in
the BlockApiCache). I'm mostly relying on c) here, in that we just won't
see this happen in practice.

Subject: [PATCH 3/7] Clean up disk <-> drive right clicking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Oh dear. I'd originally set out to *remove* logic from DiskItem — we're
so close to being able to remove this item in 1.21! However, while
looking at this code, I realised I could remove the whole Forge-specific
doesSneakBypassUse.

We now remove the use hook on the block, and override useOn on the item.
Obvious in retrospect!

Sort of closes #2125. I've really struggled to find a way to make it
clear that the information returned here is a snapshot of the current
item, and not a live view and/or proxy. Most wordings I've tried end up
feeling really clunky — given that this is a relatively rare
misunderstanding, let's not stress about this too much.

Subject: [PATCH 5/7] Fix several issues with char/paste event validation

 - Fix isValidClipboard always returning true.
 - Fix characters >=128 being rejected. We changed the signature from a
   byte to an int in 0f123b5efdca5f277f2c15208b9241d3fb9ca8fa, but
   didn't update all call sites.

   Valhalla cannot come soon enough. I would love to be able to have
   (cheap) wrapper classes for some of these types.

See Zeus-guy's comments in #860.

Subject: [PATCH 6/7] Remove air blocks from test structures

This is a bit nasty, but makes the structure files *significtly* smaller
(1/4 the size), so feels worth doing.
