98892f39e3d079c73bff7f2a5d5420fa95270497 doc: Improve setup_clean_chain documentation (Fabian Jahr)
Pull request description:
The first commit improves documentation on setup_clean_chain which is misunderstood quite frequently. Most importantly it fixes the TestShell docs which are simply incorrect.
The second commit removes the instances of `setup_clean_clain` in functional tests where it is not changing the default.
This used to be part of #19168 which also sought to rename`setup_clean_chain`.

8f073076b102b77897e5a025ae555baae3d1f671 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.

1abbdac6777bc5396d17a6772c8176a354730997 wallet: Prefer full destination groups in coin selection (Fabian Jahr)
Pull request description:
Fixes#17603 (together with #17843)
In the case of destination groups of >10 outputs existing in a wallet with `avoid_reuse` enabled, the grouping algorithm is adding left-over outputs as an "incomplete" group to the list of groups even when a full group has already been added. This leads to the strange behavior that if there are >10 outputs for a destination the transaction spending from that will effectively use `len(outputs) % 10` as inputs for that transaction.
From the original PR and the code comment I understand the correct behavior should be the usage of 10 outputs. I opted for minimal changes in the current code although there maybe optimizations possible for cases with >20 outputs on a destination this sounds like too much of an edge case right now.

6fc554f591d8ea1681b8bb25aa12da8d4f023f66 wallet: Reset reused transactions cache (Fabian Jahr)
Pull request description:
Fixes#17603 (together with #17824)
`getbalances` is using the cache within `GetAvailableCredit` under certain conditions [here](35fff5be60/src/wallet/wallet.cpp (L1826)). For a wallet with `avoid_reuse` activated this can lead to inconsistent reporting of `used` transactions/balances between `getbalances` and `listunspent` as pointed out in #17603. When an address is reused before the first transaction is spending from this address, the cache is not updated even after the transaction is sent. This means the remaining outputs at the reused address are not showing up as `used` in `getbalances`.
With this change, any newly incoming transaction belonging to the wallet marks all the other outputs at the same address as dirty.

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.
