a316e9ce265212a7c6c4ef7922420f6ecba9e7b0 refactor: add unused ArgsManager to replace gArgs (Ivan Metlushko)

Pull request description:

  Rationale: reduce use of gArgs to decouple code and simplify future maintenance and easier unit testing.

  This PR is continuation of work started in  #18926 and #18662
  It covers only places that register args in ArgsManager with `AddArgs()` or `AddHiddenArgs()`.

  Closes #19511

0fcff547d5 walletdb: Ensure that having no database handle is a failure
Previously having no database handle could still be considered a success
when BerkeleyDatabase and BerkeleyBatch were used for dummy database
things. With dedicated DummyDatabase and DummyBatch classes now, these
should fail.

27b27663849932971eb5deadb1f19234b9cd97ea walletdb: Move BerkeleyDatabase::Flush(true) to Close() (Andrew Chow)

Pull request description:

  A `WalletDatabase` abstract class is created from `BerkeleyDatabase` and is implemented by `BerkeleyDatabase`. First, to get to the point that this is possible, 4 functions need to be added to `BerkeleyDatabase`: `AddRef`, `RemoveRef`, `Open`, and `Close`.

  First the increment and decrement of `mapFileUseCount` is refactored into separate functions `AddRef` and `RemoveRef`.

  `Open` is introduced as a dummy function. This will raise an exception so that it always fails.

  `Close` is refactored from `Flush`. The `shutdown` argument in `Flush` is removed and instead `Flush(true)` is now the `Close` function.

  Split from #18971

  Requires #19325

Merge #19370: Static asserts for consistency of fee defaults
1554b54d47d7e24ce2491f57d24e56d38ceb7649 Static asserts for consistency of fee defaults. (Daniel Kraft)

Pull request description:

  This adds `static_assert`'s that ensure that the default values given for fee levels in the wallet (minimum fee and incremental feerate increase) are at least as high as the corresponding levels configured in the core node policy.  Since the core policy values are enforced by the network, it makes sense for the wallet to be conservative and above (or at least not below) this.

eac9200814fa01da6522625be01dded730b26751 walletdb: Refactor DatabaseBatch abstract class from BerkeleyBatch (Andrew Chow)

Pull request description:

  In order to support alternative database systems, we need to have a generic `Batch` class. This PR adds a `DatabaseBatch` abstract class which is implemented by `BerkeleyBatch`. `DatabaseBatch` is now the class that is used by `WalletBatch` to interact with the database. To be able to get the correct type of `DatabaseBatch`, `BerkeleyDatabase` now has a `MakeBatch` function which returns a newly constructed `std::unique_ptr<DatabaseBatch>`. For `BerkeleyDatabase`, that will be `std::unique_ptr<BerkeleyBatch>`.

  The `Read`, `Write`, `Erase`, and `Exists` template functions are moved from `BerkeleyBatch`.

  Part of #18971

Instead of removing the database transaction logs and retrying the
wallet loading, just return an error message to the user. Additionally,
specifically for DB_RUNRECOVERY, notify the user that this could be due
to different BDB versions. This error is pretty much only caused by
compiling with a newer version of BDB and then trying to open the wallet
with a version compiled with an older version of BDB.

Merge #18202: refactor: consolidate sendmany and sendtoaddress code
08fc6f6cfc3b06fd170452a766696d7b833113fa [rpc] refactor: consolidate sendmany and sendtoaddress code (Sjors Provoost)

Pull request description:

  I consolidated code between these two RPC calls, since `sendtoaddress` is essentially `sendmany` with 1 destination.

  Unless I overlooked something, the only behaviour change is that some `sendtoaddress` error codes changed from `-4` to `-6`. The release note mentions this.

  Salvaged from #18201.

Merge #19441: walletdb: don't reinitialize desc cache with multiple cache entries
a66a7a1a7060bb422eba3b8c214852416c4280d1 walletdb: don't reinitialize desc cache with multiple cache entries (Andrew Chow)

Pull request description:

  When loading descriptor caches, we would accidentally reinitialize the descriptor cache when seeing that one already exists. This should have only been initializing the cache when one does not exist. However this code itself is unnecessary as the act of looking up the cache to add to it will initialize it if it didn't already exist.

  This issue could be hit by trying to load a wallet that had imported a multisig descriptor. The wallet would fail to load.

  A test has been added to wallet_importdescriptors.py to catch this case. Another test case has also been added to check that loading a wallet with only single key descriptors works.

Pull request description:

  `SetHDChaiin`, `SetActiveScriptPubKeyMan`, and `SetWalletFlags` have a `memonly` argument which is kind of confusing, as noted in https://github.com/bitcoin/bitcoin/pull/17681#discussion_r427633081. This PR replaces those functions with `Add*` and `Load*` variants so that they follow the pattern used elsewhere in the wallet.

  `AddHDChain`, `AddActiveScriptPubKeyMan`, and `AddWalletFlags` both set their respective variables in `CWallet` and writes them to disk. These functions are used by the actions which modify the wallet such as `sethdseed`, `importdescriptors`, and creating a new wallet.

  `LoadHDChain`, `LoadActiveScriptPubKeyMan`, and `LoadWalletFlags` just set the `CWallet` variables. These functions are used by `LoadWallet` when loading the wallet from disk.

8f1bcf8b7b6e47c05f2e43dd98ec3505b888d8b3 walletdb: Combine VerifyDatabaseFile and VerifyEnvironment (Andrew Chow)

Pull request description:

  The `BerkeleyBatch` class has 4 static functions that operate on `BerkeleyDatabase` or `BerkeleyEnvironment`. It doesn't make sense for these to be standalone nor for them to be static functions. So instead, move them from `BerkeleyBatch` into `BerkeleyDatabase` and make them member functions instead of static.

  `BerkeleyBatch::VerifyEnvironment` and `BerkeleyBatch::VerifyDatabaseFile` are combined into a single `BerkeleyDatabase::Verify` function that operates on that `BerkeleyDatabase` object.

  `BerkeleyBatch::Rewrite` and `BerkeleyBatch::PeriodicFlush` both took a `BerkeleyDatabase` as an argument and did stuff on it. So we just make it a member function so it doesn't need to take a database as an argument.

  Part of #18971

Pull request description:

  The utility function is primarily useful to dereference pointer types, which are known to be not null at that time.

  For example, the ArgsManager is known to exist when the wallets are started: https://github.com/bitcoin/bitcoin/pull/18923/files#diff-fdb2a1a1d8bc790fcddeb6cf5a42ac55R503 . Instead of silently relying on that assumption, `Assert` can be used to abort the program and avoid UB should the assumption ever be violated.

a66a7a1a70 walletdb: don't reinitialize desc cache with multiple cache entries
When loading descriptor caches, we would accidentally reinitialize the
descriptor cache when seeing that one already exists. This should have
only been initializing the cache when one does not exist. However this
code itself is unnecessary as the act of looking up the cache to add to
it will initialize it if it didn't already exist.

This issue could be hit by trying to load a wallet that had imported a
multisig descriptor. The wallet would fail to load.

A test has been added to wallet_importdescriptors.py to catch this case.
Another test case has also been added to check that loading a wallet
with only single key descriptors works.

Merge #19413: refactor: Remove confusing BlockIndex global
fa0dfdf447d5b84a1849dc823d8508463600136a refactor: Remove confusing BlockIndex global (MarcoFalke)

Pull request description:

  The global `::BlockIndex()` is problematic for several reasons:

  * It returns a mutable reference to the block tree, without the appropriate lock annotation (`m_block_index` is guarded by `cs_main`). The current code is fine, but in the future this might lead to accidental races and data corruption.
  * The rpc server shouldn't rely on node globals, but rather a context that is passed in to the RPC method.
  * Tests might want to spin up their own block tree, and thus should also not rely on a single global.

  Fix all issues by removing the global

72f6bec1da198764d4648a10a61c485e7ab65e9e rpc: show both UTXOs in decodepsbt (Andrew Chow)

Pull request description:

  Due to recent changes to hardware wallets, the full previous transaction will need to be provided for segwit inputs. Since some software may be checking for the existence of a `witness_utxo` to determine whether to produce a segwit signature, we keep that field to ease the transition.

  Because all of the sanity checks implemented by the `IsSane` functions were related to having mixed segwit and non-segwit data in a PSBT, those functions are removed as those checks are no longer proper.

  Some tests are updated/removed to accommodate this and a simple test added to check that both UTXOs are being added to segwit inputs.

  As discussed in the wallet IRC meeting, our own signer will not require `non_witness_utxo` for segwit inputs.

Pull request description:

  `OutputType::CHANGE_AUTO` is problematic for several reasons:

  * An output that is not change must never be described by `CHANGE_AUTO`. Simply allowing that option makes the code confusing and review harder than it needs to be.
  * To make review even harder, `CHANGE_AUTO` requires `-Wswitch` to be disabled for `OutputType`

  Fix both issues by removing `CHANGE_AUTO` and then enabling `-Wswitch` for `OutputType`
