b026e318c3 validation: Move FindForkInGlobalIndex to BlockManager
[META] This commit should be followed up by removing the comments and
       assertions meant only to show that the change is correct.

FindForkInGlobalIndex only acts on BlockManager.

Note to reviewers: Since FindForkInGlobalIndex is always called with
::ChainActive() as its first parameter, it is possible to move
FindForkInGlobalIndex to CChainState and remove this const CChain&
parameter to instead use m_chain. However, it seems like the original
intention was for FindForkInGlobalIndex to work with _any_ chain, not
just the current active chain. Let me know if this should be changed.

f92dc6557a validation: Guard the active_chainstate with cs_main
This avoids a potential race-condition where a thread is reading the
ChainstateManager::m_active_chainstate pointer while another one is
writing to it. There is no portable guarantee that reading/writing the
pointer is thread-safe.

This is also done in way that mimics ::ChainstateActive(), so the
transition from that function to this method is easy.

Pull request description:

  This PR:
  - gets rid of `boost::thread_group` in the `CCheckQueue` class
  - allows thread safety annotation usage in the `CCheckQueue` class
  - is alternative to #14464 (https://github.com/bitcoin/bitcoin/pull/18710#issuecomment-616618525, https://github.com/bitcoin/bitcoin/pull/18710#issuecomment-617291612)

  Also, with this PR (I hope) it could be easier to resurrect a bunch of brilliant ideas from #9938.

c943282b5e validation: remove redundant check on pindex
This removes a conditional that checks if pindex is equal to nullptr.
This check is redundant because the branch where pindex is set returns at an earlier time. Additionaly, The independence of the earlier and later pindex is made clearer.

7ff05358a9 [mempool] Remove error suppression on upgrade
In 0.21, we added unbroadcast txids to mempool.dat. Commit 9c8a55d
added a try-block to prevent throwing a "failed to deserialize mempool data"
error when a user upgrades from 0.21 to 0.22. This exception handling is no
longer useful, so now we can remove it.

Merge #18766: Disable fee estimation in blocksonly mode (by removing the fee estimates global)
4e28753f60 feestimator: encapsulate estimation file logic (Antoine Poinsot)
e8ea6ad9c1 init: don't create a CBlockPolicyEstimator if we don't relay transactions (Antoine Poinsot)
86ff2cf202 Remove the remaining fee estimation globals (Antoine Poinsot)
03bfeee957 interface: remove unused estimateSmartFee method from node (Antoine Poinsot)

Pull request description:

  If the `blocksonly` mode is turned on after running with transaction
  relay enabled for a while, the fee estimation will serve outdated data
  to both the internal wallet and to external applications that might be
  feerate-sensitive and make use of `estimatesmartfee` (for example a
  Lightning Network node).

  This has already caused issues (for example https://github.com/bitcoin/bitcoin/issues/16840 (C-lightning), or https://github.com/lightningnetwork/lnd/issues/2562 (LND)) and it seems prudent to fail rather than to give inaccurate values.

  This fixes #16840, and closes #16890 which tried to fix the symptoms (RPC) but not the cause as mentioned by sdaftuar :
  > If this is a substantial problem, then I would think we should take action to protect our own wallet users as well (rather than hide the results of what our fee estimation would do!).

Remove the remaining fee estimation globals
This moves the CBlockPolicyEstimator to the NodeContext, which get rids
of two globals and allows us to conditionally create the
CBlockPolicyEstimator (and to remove a circular dep).

ab283556b0 Merge db88db4727 into merged_master (Bitcoin PR #19339)
Changes API for AcceptToMemoryPool to no longer check maximum fee; we remove
this check from interfaces::CChain::testPeginClaimAcceptance. This is fine,
the check never should have been there (this method's job is to notice double
claim attempts and provide a more helpful message to the user; other mempool
failures should be caught later in the `claimrawpegin` logic when we call
`pwallet->commitTransaction` which actually subits to the mempool). It was
only checking fees because the API made it easier to do so than to not.

This commit adds signet support, which is a little bit silly/redundant for us :)
Was a surprisingly easy merge to handle, and hopefully in future Core is more
mindful of signed blocks when they are changing code architecture.

I had to change a couple lines of src/signet.cpp to add blank assets to the
CTxOuts and to find transaction input scriptWitnesses. No need to add any
other tx witness data (and the CAsset()s that I did add to make things compile
won't be used..) because signet will always have g_con_elementsmode off.

2a0cf12ecc Merge 07087051af into merged_master (Bitcoin PR #19556)
Added a method testPeginClaimAcceptance to interfaces::CChain. It is not clear
to me that this is meaningfully different from the existing method broadcastTransaction
(with the `relay` flag set to false so it doesn't actually broadcast), except
that this method returns the TxValidationState, which we display to the user
in the RPC error. Worth revisiting this.

Another nonobvious change was replacing a block of mempool-searching logic
in wallet/rpcwallet.cpp with the single line `pwallet->chain().findCoins(coins)`.
This I stole from the current state of upstream #17211, our favorite in-progress
PR from which the original logic came.
