00eeb31c76 scripted-diff: rename CChainState -> Chainstate (James O'Beirne)
Pull request description:
Alright alright alright, I know: we hate refactors. We especially hate cosmetic refactors.
Nobody knows better than I that changing broad swaths of code out from under our already-abused collaborators, only to send a cascade of rebase bankruptcies, is annoying at best and sadistic at worst. And for a rename! The indignation!
But just for a second, imagine yourself. Programming `bitcoin/bitcoin`, on a sandy beach beneath a lapis lazuli sky. You go to type the name of what is probably the most commonly used data structure in the codebase, and you *only hit shift once*.
What could you do in such a world? You could do anything. [The only limit is yourself.](https://zombo.com/)

So maybe you like the idea of this patch but really don't want to deal with rebasing. You're in luck!
Here're the commands that will bail you out of rebase bankruptcy:
```sh
git rebase -i $(git merge-base HEAD master) \
-x 'sed -i "s/CChainState/Chainstate/g" $(git ls-files | grep -E ".*\.(py|cpp|h)$") && git commit --amend --no-edit'
# <commit changed?>
git add -u && git rebase --continue
```

~~Anyway I'm not sure how serious I am about this, but I figured it was worth proposing.~~ I have decided I am very serious about this.
Maybe we can have nice things every once in a while?

faa3d38ec6 refactor: Pass reference to LookUpStats (MacroFake)
Pull request description:
I find it confusing to have an interface that accepts nullptr, but immediately crashes the program when someone does pass nullptr.
Fix that.
Also some include fixups.

In order to prevent memory DoS, we must ensure that we don't accept a new
header into memory until we've performed anti-DoS checks, such as verifying
that the header is part of a sufficiently high work chain. This commit adds a
new argument to AcceptBlockHeader() so that we can ensure that all call-sites
which might cause a new header to be accepted into memory have to grapple with
the question of whether the header is safe to accept, or needs further
validation.
This patch also fixes two places where low-difficulty-headers could have been
processed without such validation (processing an unrequested block from the
network, and processing a compact block).

Pull request description:
Start transitioning index code away from using internal node types like `CBlockIndex` and `CChain` so index code is less coupled to node code and index code will later be able to stop locking cs_main and sync without having to deal with validationinterface race conditions, and so new indexes are easier to write and can run as plugins or separate processes.

The indexing codepath logic in node/coinstats.cpp is simple enough to be
moved into CoinStatsIndex::LookUpStats, avoiding an additional layer of
function calls. Callers are modified accordingly.
Also, add 2 missed BOOST_CHECKs to the coinstatsindex_initial_sync unit
test.
Currently, CCoinsStats is a struct with both in-params and out-params
where the hash_type and index_requested members are the only in-params.
This change removes CCoinsStats' hash_type in-param member and adds it
to the relevant functions instead.
[META] In subsequent commits, all of CCoinsStats' members which serve as
in-params will be moved out so as to make CCoinsStats a pure
out-param struct.
