Introduces functionality to detect when limited peers connections
are desirable or not. Ensuring that the new connections desirable
services flags stay relevant throughout the software's lifecycle.
(Unlike the previous approach, where once the validation IBD flag
was set, the desirable services flags remained constant forever).
This will let us recover from stalling scenarios where the node had
successfully synced, but subsequently dropped connections and remained
inactive for a duration longer than the limited peers threshold (the
timeframe within which limited peers can provide blocks). Then, upon
reconnection to the network, the node may end up only establishing
connections with limited peers, leading to an inability to synchronize
the chain.
This also fixes a possible limited peers threshold violation during IBD,
when the user configures `-maxtipage` further than the BIP159's limits.
This rule violation could lead to sync delays and, in the worst-case
scenario, trigger the same post-IBD stalling scenario (mentioned above)
but during IBD.
In the process of doing so, refactor `ConsumeNetAddr()` to generate the
addresses from IPv4, IPv6, Tor, I2P and CJDNS networks in the same way -
by preparing some random stream and deserializing from it. Similar code
was already found in `RandAddr()`.
Hopefully, refraining users from modifying the file unless they are
certain about the potential consequences.

282b12ddb0 refactor: remove CTxMemPool::queryHashes() (stickies-v)
Pull request description:
`CTxMemPool::queryHashes()` is only used in `MempoolToJSON()`, where it can just as easily be replaced with the more general `CTxMemPool::entryAll()`. No behaviour change, just cleans up the code.

Fixes a (rare) intermittency issue in wallet_import_rescan.
Since we use `subtract_fee_from_outputs=[0]` in the `send` command,
the output amount must at least be as large as the fee we're paying.
Instead turning tx.vout into a vector of `CRecipient`, make `FundTransaction`
take a `CRecipient` vector directly. This allows us to remove SFFO logic from
the wrapper RPC `FundTransaction` since the `CRecipient` objects have already
been created with the correct SFFO values. This also allows us to remove
SFFO from both `FundTransaction` function signatures.
This sets us up in a future PR to be able to use these RPCs with BIP352
static payment codes.
Move validation logic out of `CreateRecipients` and instead take the
already validated outputs from `ParseOutputs` as an input.
Move SFFO parsing out of `CreateRecipients` into a new function,
`InterpretSubtractFeeFromOutputsInstructions`. This takes the SFFO instructions
from `sendmany` and `sendtoaddress` and turns them into a set of integers.
In a later commit, we will also move the SFFO parsing logic from
`FundTransaction` into this function.
Worth noting: a user can pass duplicate addresses and addresses that dont exist
in the transaction outputs as SFFO args to `sendmany` and `sendtoaddress`
without triggering a warning. This behavior is preserved in to keep this commit
strictly a refactor.
Move the parsing and validation out of `AddOutputs` into its own function,
`ParseOutputs`. This allows us to re-use this logic in `ParseRecipients` in a
later commit, where the code is currently duplicated.
The new `ParseOutputs` function returns a CTxDestination,CAmount tuples.
This allows the caller to then translate the validated outputs into
either CRecipients or CTxOuts.
Move the univalue formatting logic out of AddOutputs and into its own function,
`NormalizeOutputs`. This allows us to re-use this logic in later commits.
If the serialized transaction passed to `fundrawtransaction` contains
duplicates, they will be deserialized and added to the transaction. Add
a test to ensure this behavior is not changed during the refactor.
A user can pass any number of duplicated and unrelated addresses as an
SFFO argument to `sendmany` and the RPC will not throw an error (note,
all the rest of the RPCs which take SFFO as an argument will error if
the user passes duplicates or specifies outputs not present in the
transaction). Add a test to ensure this behavior is not changed during
the refactor.

`CWallet::GetEncryptionKey()` would return a reference to the internal
`CWallet::vMasterKey`, guarded by `CWallet::cs_wallet`, which is unsafe.
Returning a copy would be a shorter solution, but could have security
implications of the master key remaining somewhere in the memory even
after `CWallet::Lock()` (the current calls to
`CWallet::GetEncryptionKey()` are safe, but that is not future proof).
So, instead of `EncryptSecret(m_storage.GetEncryptionKey(), ...)`
change the `GetEncryptionKey()` method to provide the encryption
key to a given callback:
`m_storage.WithEncryptionKey([](const CKeyingMaterial& k) { EncryptSecret(k, ...); })`
This silences the following (clang 18):
```
wallet/wallet.cpp:3520:12: error: returning variable 'vMasterKey' by reference requires holding mutex 'cs_wallet' [-Werror,-Wthread-safety-reference-return]

3ba815b42d Make v2transport default for addnode RPC when enabled (Pieter Wuille)
Pull request description:
Since #29058, several types of manually configured connections will attempt v2 connections when `-v2transport` is enabled, except for the `addnode` RPC, as that one has an explicit argument to enable or disable.
Make the default for that RPC match the `-v2transport` setting so the behavior matches that of other manual connections from a user perspective.

Service flags received from the peer-to-peer network are handled differently, depending on how we receive them.

df30247705 [test] import descriptor wallet with reorged parent + IsFromMe child in mempool (glozow)
c3d02be536 [test] rescan legacy wallet with reorged parent + IsFromMe child in mempool (Gloria Zhao)
Pull request description:
Originally motivated by #29019, which reverts back to having `requestMempoolTransactions` emit `transactionAddedToMempool` in `mapTx` default order instead of `GetSortedDepthAndScore` order.
It's important that these notifications happen in topological order, otherwise the wallet rescan may miss transactions that belong to it. Notably, checking whether a transaction `IsFromMe` requires knowing its inputs, which may be from a mempool parent.
When using `mapTx` order, a parent may come later than its child if it was added from a block disconnected in a reorg.
This PR adds a test for this case.

Updating it introduces some new options. For example specifying the

It's preferable to use type-safe transaction identifiers to avoid
confusing txid and wtxid. The next commit will add a reference to this

of adding new uses of uint256.
