e4709c7b56 Start using init makeNode, makeChain, etc methods (Russell Yanofsky)
Pull request description:
Use `interfaces::Init::make*` methods instead of `interfaces::Make*` functions, so interfaces can be constructed differently in different executable without having to change any code. (So for example `bitcoin-gui` can make an `interfaces::Node` pointer that communicates with a `bitcoin-node` subprocess, while `bitcoin-qt` can make an `interfaces::Node` pointer that controls node code in the same process.)

The long term feerate is really the highest feerate that the user is
comfortable with making consolidatory transactions. This is should thus
be something that can be configured by the user via a new startup option
-consolidatefeerate. The default value is 10 sat/vbyte, chosen
arbitrarily (it seems like a reasonable number).

e6fe1c37d0 rpc: Improve avoidpartialspends and avoid_reuse documentation (Fabian Jahr)
8f073076b1 wallet: Increase OUTPUT_GROUP_MAX_ENTRIES to 100 (Fabian Jahr)
Pull request description:
Follow-up to #17824.
This increases OUTPUT_GROUP_MAX_ENTRIES to 100 which means that OutputGroups will now be up to 100 outputs large, up from previously 10. The main motivation for this change is that during the PR review club on #17824 [several participants signaled](https://bitcoincore.reviews/17824.html#l-339) that 100 might be a better value here.
I think fees should be manageable for users but more importantly, users should know what they can expect when using the wallet with this configuration, so I also tried to clarify the documentation on `-avoidpartialspends` and `avoid_reuse` a bit. If there are other additional ways how or docs where users can be made aware of the potential consequences of using these parameters, please let me know. Another small upside is that [there seem to be a high number of batching transactions with 100 and 200 inputs](https://miro.medium.com/max/3628/1*sZ5eaBSbsJsHx-J9iztq2g.png)([source](https://medium.com/@hasufly/an-analysis-of-batching-in-bitcoin-9bdf81a394e0)) giving these transactions a bit of a larger anonymity set, although that is probably a very weak argument.

Since we want tests to run quickly, and since tests do a lot more db
operations than expected we expect to see in actual usage, we disable
sqlite's syncing behavior to make db operations run much faster. This
syncing behavior is necessary for normal operation as it helps guarantee
that data won't become lost or corrupted, but in tests, we don't care
about that.
Detect version conflicts between the run-time BerkeleyDB library and the one used during compilation.
This is very unsafe (can result in anything from crashes to corruption) so shut down when one is detected.
No longer create a default wallet. The default wallet will still be
loaded if it exists and not other wallets were specified (anywhere,
including settings.json, bitcoin.conf, and command line).
Tests are updated to be started with -wallet= if they need the default
wallet.
Added test to wallet_startup.py testing that no default wallet is
created and that it is loaded if it exists and no other wallets were
specified.
3340dbadd3 Remove -zapwallettxes (Andrew Chow)

It's not clear what use there is to keeping `-zapwallettxes` given that it's intended usage has been superseded by `abandontransaction`. So this removes it outright.

-zapwallettxes is made a hidden option to inform users that it is
removed and they should be using abandontransaction to do the stuck
transaction thing.
Add WalletClient interface so node interface is cleaner and don't need
wallet-specific methods.
The new NodeContext::wallet_client pointer will also be needed to eliminate
global wallet variables like ::vpwallets, because createWallet(), loadWallet(),
getWallets(), etc methods called by the GUI need a way to get a reference to
the list of open wallets if it is no longer a global variable.
Also tweaks splash screen registration for load wallet events to be delayed
until after wallet client is created.
7f13dfb587 test: test the implicit avoid partial spends functionality (Karl-Johan Alm)
b82067bf69 wallet: try -avoidpartialspends mode and use its result if fees are below threshold (Karl-Johan Alm)
Pull request description:
The `-avoidpartialspends` feature is normally disabled, as it may affect the optimal fee for payments. This PR introduces a new parameter `-maxapsfee` (max avoid partial spends fee) which acts on the following values:
* -1: disable partial spend avoidance completely (do not even try it)
* 0: only do partial spend avoidance if fees are the same or better as the regular coin selection
* 1..∞: use APS variant if the absolute fee difference is less than or equal to the max APS fee
For values other than -1, the code will now try partial spend avoidance once, and if that gives a value within the accepted range, it will use that.
Example: -maxapsfee=0.00001000 means the wallet will do regular coin select, APS coin select, and then pick AKS iff the absolute fee difference is <= 1000 satoshi.
Edit: updated this to reflect the fact we are now using a max fee.

This maintains a persistent list of wallets stored in settings that will
automatically be loaded on startup. Being able to load a wallet automatically
on startup will be more useful in the GUI when the option to create wallets is
added in #15006, but it's reasonable to expose this feature by RPC as well.

Pull request description:
`-upgradewallet` is largely incompatible with many recent wallet features and versions. For example, it was disabled if multiple wallets were used and would not work with encrypted wallets that were being upgraded to HD.
This PR does away with the old method of upgrading upon startup and instead allows users to upgrade their wallets via an `upgradewallet` RPC. This does largely the same thing as the old `-upgradewallet` option but because the wallet is loaded, it can be unlocked to upgrade to HD. Furthermore it is compatible with multiwallet as it works on the individual wallet that is specified by the RPC.

If after a backup, an address is issued beyond the initial
keypool range and none of the addresses in this range
is seen onchain, if a wallet is restored from backup, even in
case of rescan, funds may be loss due to the look-ahead
buffer not being incremented and so restored wallet not detecting
onchain out-of-range address as derived from its seed.
This scenario is theoretically unavoidable due to the requirement
of the keypool to have a max size. However, given the default
keypool size, this is unlikely. Document better keypool size
implications to avoid user setting a too low value.
Prior to this PR, the wallet would not allow the `-rescan` option at
startup if pruning was enabled. This is unnecessarily restrictive. It
should be possible to rescan if pruning is enabled, as long as no blocks
have actually been pruned yet.
Remove the pruning check from WalletInit::ParameterInteraction(). If any
blocks have been pruned, that will be caught in CreateWalletFromFile().
Before it was 0 by default for main and 20000 for test and regtest.
Now it is 0 by default for all chains, thus there's no need to call Params().
Also now the default for main is properly documented

Pull request description:
Add a new wallet flag called `avoid_reuse` which, when enabled, will keep track of when a specific destination has been spent from, and will actively "blacklist" any new UTXOs which send to an already-spent-from destination.
This improves privacy, as a payer could otherwise begin tracking a payee's wallet by regularly peppering a known UTXO with dust outputs, which would then be scooped up and used in payments by the payee, allowing the payer to map out (1) the inputs owned by the payee and (2) the destinations to which the payee is making payments.
This replaces #10386 and together with the (now merged) #12257 it addresses #10065 in full. The concerns raised in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381 are also addressed due to #12257.
