At verification time, the to be precomputed data can be inferred from
the transaction itself. For signing, the necessary witnesses don't
exist yet, so just permit precomputing everything in that case.
This provides a means to pass in a PrecomputedTransactionData object to
the MutableTransactionSignatureCreator, allowing the prevout data to be
passed into the signature hashers. It is also more efficient.
This data structures stores all information necessary for spending a taproot
output (the internal key, the Merkle root, and the control blocks for every
script leaf).
It is added to signing providers, and populated by the tr() descriptor.

This PR:
- removes slots whose only job is to emit a signal, since we can use the signal as a slot
- connects the`WalletView::outOfSyncWarningClicked` signal to the `BitcoinGUI::showModalOverlay` slot directly, and removes intermediate `WalletFrame` slot and signal
- split from #29

a92485b2c2 addrman: use unordered_map instead of map (Vasil Dimov)
Pull request description:
`CAddrMan` uses `std::map` internally even though it does not require
that the map's elements are sorted. `std::map`'s access time is
`O(log(map size))`. `std::unordered_map` is more suitable as it has a
`O(1)` access time.
This patch lowers the execution times of `CAddrMan`'s methods as follows
(as per `src/bench/addrman.cpp`):
```
AddrMan::Add(): -3.5%
AddrMan::GetAddr(): -76%
AddrMan::Good(): -0.38%
AddrMan::Select(): -45%

f47e802839 Rearrange fillPSBT arguments (Russell Yanofsky)
Pull request description:
Move fillPSBT inout argument before output-only arguments. This is a nice thing to do to keep the interface style [consistent](https://google.github.io/styleguide/cppguide.html#Inputs_and_Outputs). But motivation is to work around a current limitation of the libmultiprocess code generator (which figures out order of inout parameters by looking at input list, but more ideally would use the output list).

This is the last bundle in the #20158 series. Thanks everyone for their diligent review.
I would like to call attention to https://github.com/bitcoin/bitcoin/issues/21766, where a few leftover improvements were collated.
- Remove globals:
- `ChainstateManager g_chainman`
- `CChainState& ChainstateActive()`
- `CChain& ChainActive()`
- Remove all review-only assertions.

493fb47c57 Make SetupServerArgs callable without NodeContext (Russell Yanofsky)
Pull request description:
`bitcoin-gui` code needs to call `SetupServerArgs` but will not have a `NodeContext` object if it is communicating with an external `bitcoin-node` process, so this just passes `ArgsManager` directly.

There are some mutable, global state variables that are currently reset
by UnloadBlockIndex such as pindexBestHeader which should be cleaned up
whenever the ChainstateManager is unloaded/reset/destructed/etc.
Not cleaning them up leads to bugs like a use-after-free that happens
like so:
1. At the end of a test, ChainstateManager is destructed, which also
destructs BlockManager, which calls BlockManager::Unload to free all
CBlockIndexes in its BlockMap
2. Since pindexBestHeader is not cleaned up, it now points to an invalid
location
3. Another test starts to init, and calls LoadGenesisBlock, which calls
AddToBlockIndex, which compares the genesis block with an invalid
location
4. Cute puppies perish by the hundreds
Previously, for normal codepaths (e.g. bitcoind), we relied on the fact
that our program will be unloaded by the operating system which
effectively resets these variables. The one exception is in QT tests,
where these variables had to be manually reset.
Since now ChainstateManager is no longer a global, we can just put this
logic in its destructor to make sure that callers are always correct.
Over time, we should probably move these mutable global state variables
into ChainstateManager or CChainState so it's easier to reason about
their lifecycles.
Move fillPSBT input-output argument before output-only arguments. This is a
temporary workaround which can go away with improvements to libmultiprocess
code generator. Currently code generator figures out order of input-output
parameters by looking at input list, but it would make more sense for it to
take order from output list, so input-only parameters still have to be first
but there is more flexibility for the other parameters.

Pull request description:
The QueuedBlock struct contains a `fValidatedHeaders` field that indicates whether we have already validated a header for the requested block. Since headers-first syncing, we only request blocks where the header is already validated, so `fValidatedHeaders` is always true. Remove it and clean up the logic that uses that field.
Likewise, QueuedBlock contains a `hash` field that is set to the block hash. Since headers-first syncing, we always have a CBlockIndex, which contains the block hash, so remove the redundant `hash` field.
Tidy up the logic and rename functions to better indicate what they're doing.
