guix: Record precious directories and add guix-clean
Many users have reported problems that stem from having an unclean
working tree. To that end, I've written a guix-clean script which should
help reset the working tree while respecting user-specified precious
directories.
Precious directories, such as:
- SOURCES_PATH
- BASE_CACHE
- SDK_PATH
- OUTDIR
Should be preserved when cleaning the working tree, and are thus
recorded in ./contrib/guix/var/precious_dirs.
The ./contrib/guix/guix-clean script is able to parse that file and make
sure to avoid them when cleaning out the working tree.

Pull request description:
Following #17261, the way to sign transactions, PSBTs, and messages was to use `GetSigningProvider()` and get a `SigningProvider` containing the private keys. However this may not be feasible for future `ScriptPubKeyMan`s, such as for hardware wallets. Instead of exporting a `SigningProvider` containing private keys, we need to pass these things into the `ScriptPubKeyMan` (via `CWallet`) so that they can do whatever is needed internally to sign them. This is largely a refactor as the logic of processing transactions, PSBTs, and messages for is moved into `LegacyScriptPubKeyMan` and `CWallet` instead of being handled by the caller (e.g. `signrawtransaction`).
To help with this, I've refactored the 3(!) implementations of a `SignTransaction()` function into one generic one. This function will be called by `signrawtransactionwithkey` and `LegacyScriptPubKeyMan::SignTransaction()`. `CWallet::CreateTransaction()` is changed to call `CWallet::SignTransaction()` which in turn, calls `LegacyScriptPubKeyMan::SignTransaction()`. Other `ScriptPubKeyMan`s may implement `SignTransaction()` differently.
`FillPSBT()` is moved to be a member function of `CWallet` and the `psbtwallet.cpp/h` files removed. It is further split so that `CWallet` handles filling the UTXOs while the `ScriptPubKeyMan` handles adding keys, derivation paths, scripts, and signatures. In the end `LegacyScriptPubKeyMan::FillPSBT` still calls `SignPSBTInput`, but the `SigningProvider` is internal to `LegacyScriptPubKeyMan`. Other `ScriptPubKeyMan`s may do something different.
A new `SignMessage()` function is added to both `CWallet` and `ScriptPubKeyMan`. Instead of having the caller (i.e. `signmessage` or the sign message dialog) get the private key, hash the message, and sign, `ScriptPubKeyMan` will now handle that (`CWallet` passes through to the `ScriptPubKeyMan`s as it does for many functions). This signing code is thus consolidated into `LegacyScriptPubKeyMan::SignMessage()`, though other `ScriptPubKeyMan`s may implement it differently. Additionally, a `SigningError` enum is introduced for the different errors that we expect to see from `SignMessage()`.
Lastly, `GetSigningProvider()` is renamed to `GetPublicSigningProvider()`. It will now only provide pubkeys, key origins, and scripts. `LegacySigningProvider` has it's `GetKey` and `HaveKey` functions changed to only return false. Future implementations should return `HidingSigningProvider`s where private keys are hidden.
Other things like `dumpprivkey` and `dumpwallet` are not changed because they directly need and access the `LegacyScriptPubKeyMan` so are not relevant to future changes.

Pull request description:
Continuation of wallet boxes project.
Actually makes ScriptPubKeyMan an interface which LegacyScriptPubkeyMan. Moves around functions and things from CWallet into LegacyScriptPubKeyMan so that they are actually separate things without circular dependencies.
***
Introducing the `ScriptPubKeyMan` (short for ScriptPubKeyManager) for managing scriptPubKeys and their associated scripts and keys. This functionality is moved over from `CWallet`. Instead, `CWallet` will have a pointer to a `ScriptPubKeyMan` for every possible address type, internal and external. It will fetch the correct `ScriptPubKeyMan` as necessary. When fetching new addresses, it chooses the `ScriptPubKeyMan` based on address type and whether it is change. For signing, it takes the script and asks each `ScriptPubKeyMan` for whether that `ScriptPubKeyMan` considers that script `IsMine`, whether it has that script, or whether it is able to produce a signature for it. If so, the `ScriptPubKeyMan` will provide a `SigningProvider` to the caller which will use that in order to sign.
There is currently one `ScriptPubKeyMan` - the `LegacyScriptPubKeyMan`. Each `CWallet` will have only one `LegacyScriptPubKeyMan` with the pointers for all of the address types and change pointing to this `LegacyScriptPubKeyMan`. It is created when the wallet is loaded and all keys and metadata are loaded into it instead of `CWallet`. The `LegacyScriptPubKeyMan` is primarily made up of all of the key and script management that used to be in `CWallet`. For convenience, `CWallet` has a `GetLegacyScriptPubKeyMan` which will return the `LegacyScriptPubKeyMan` or a `nullptr` if it does not have one (not yet implemented, but callers will check for the `nullptr`). For purposes of signing, `LegacyScriptPubKeyMan`'s `GetSigningProvider` will return itself rather than a separate `SigningProvider`. This will be different for future `ScriptPubKeyMan`s.
The `LegacyScriptPubKeyMan` will also handle the importing and exporting of keys and scripts instead of `CWallet`. As such, a number of RPCs have been limited to work only if a `LegacyScriptPubKeyMan` can be retrieved from the wallet. These RPCs are `sethdseed`, `addmultisigaddress`, `importaddress`, `importprivkey`, `importpubkey`, `importmulti`, `dumpprivkey`, and `dumpwallet`. Other RPCs which relied on the wallet for scripts and keys have been modified in order to take the `SigningProvider` retrieved from the `ScriptPubKeyMan` for a given script.
Overall, these changes should not effect how everything actually works and the user should experience no difference between having this change and not having it. As such, no functional tests were changed, and the only unit tests changed were those that were directly accessing `CWallet` functions that have been removed.
This PR is the last step in the [Wallet Structure Changes](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes).

* Move wallet enums to walletutil.h
* MOVEONLY: Move key handling code out of wallet to keyman file
Start moving wallet and ismine code to scriptpubkeyman.h, scriptpubkeyman.cpp
The easiest way to review this commit is to run:
git log -p -n1 --color-moved=dimmed_zebra
And check that everything is a move (other than includes and copyrights comments).
This commit is move-only and doesn't change code or affect behavior.
* Refactor: Split up CWallet and LegacyScriptPubKeyMan and classes
This moves CWallet members and methods dealing with keys to a new
LegacyScriptPubKeyMan class, and updates calling code to reference the new
class instead of CWallet.
Most of the changes are simple text replacements and variable substitutions
easily verified with:
git log -p -n1 -U0 --word-diff-regex=.
The only nontrivial chunk of code added is the new LegacyScriptPubKeyMan class
declaration, but this code isn't new and is just selectively copied and moved
from the previous CWallet class declaration. This can be verified with:
git log -p -n1 --color-moved=dimmed_zebra src/wallet/scriptpubkeyman.h src/wallet/wallet.h
or
git diff HEAD~1:src/wallet/wallet.h HEAD:src/wallet/scriptpubkeyman.h
This commit does not change behavior.
* Renamed classes in scriptpubkeyman
* Fixes for conflicts, compilation and linkage errors due to previous commits
* Reordered methods in scriptpubkeyman to make further backports easier
* Reordered methods in scriptpubkeyman to make further backports easier (part II)

71af793512100ee7d508c3fb815af47925fe80ba scripts: fix check-symbols & check-security argument passing (fanquake)
Pull request description:
The first argument in `bin_PROGRAMS` (`bitcoind`) was being silently consumed and never passed into the [`security-check.py`](https://github.com/bitcoin/bitcoin/blob/master/contrib/devtools/security-check.py) or [`symbol-check.py`](https://github.com/bitcoin/bitcoin/blob/master/contrib/devtools/symbol-check.py) scripts.
This seems to have been the case since the scripts were added to the makefile in f3d3eaf78e.
Example of the behavior:
```python
# touch a, touch b, touch c
# python3 args.py < a b c
import sys
if __name__ == '__main__':
print(sys.argv)
# ['args.py', 'b', 'c']
# if you add some lines to "a",
# you'll see them here..
for line in sys.stdin:
print(line)
```

Pull request description:
This uses `otool -vh` to print the mach header and look for the `PIE` flag:
```bash
otool -vh src/bitcoind

MH_MAGIC_64 X86_64 ALL LIB64 EXECUTE 24 2544 NOUNDEFS DYLDLINK TWOLEVEL WEAK_DEFINES BINDS_TO_WEAK PIE
```
From [`mach-o/loader.h`](https://opensource.apple.com/source/cctools/cctools-927.0.2/include/mach-o/loader.h.auto.html):

#define MH_PIE 0x200000 /* When this bit is set, the OS will
load the main executable at a
random address. Only used in
