b857ac60d9 test/fuzz: Invoke LoadMempool via CChainState
Not only does this increase coverage, it is also more correct in that
when ::LoadMempool is called with a mempool and chainstate, it calls
AcceptToMemoryPool with just the chainstate.

AcceptToMemoryPool will then act on the chainstate's mempool via
CChainState::GetMempool, which may be different from the mempool
originally passed to ::LoadMempool. (In this fuzz test's case, it
definitely is different)

Also, move DummyChainstate to its own file since it's now used by the
validation_load_mempool fuzz test to replace CChainState's m_mempool.

Pull request description:

  The return value of the `push*` helpers is never used, but important to determine if the operation was successful. One way to fix this would be to add the "nodiscard" attribute. However, this would make the code (and this diff) overly verbose for no reason.

  So fix it by removing the never used return value. Also, fail verbosely in case of a programming mistake.

Pull request description:

  This adds Miniscript support for Output Descriptors without any signing logic (yet). See the OP of #24147 for a description of Miniscript and a rationale of having it in Bitcoin Core.
  On its own, this PR adds "watchonly" support for Miniscript descriptors in the descriptor wallet. A follow-up adds signing support.

  A minified corpus of Miniscript Descriptors for the `descriptor_parse` fuzz target is available at https://github.com/bitcoin-core/qa-assets/pull/92.
  The Miniscript descriptors used in the unit tests here and in #24149 were cross-tested against the Rust implementation at https://github.com/rust-bitcoin/rust-miniscript.

  This PR contains code and insights from Pieter Wuille.

fc5eb528f7 [tests] Connect peer in outbound_slow_chain_eviction by sending p2p messages
Prior to this commit, the peer was connected, and then the services and
connectivity fields in the CNode object were manually set. Instead, send
p2p `version` and `verack` messages, and have net_processing's internal
logic set the state of the node.

This ensures that the node's internal state is consistent with how it
would be set in the live code.

Prior to this commit, `dummyNode1.nServices` was set to `NODE_NONE`
which was not a problem since `CNode::fClient` and
`CNode::m_limited_node` are default initialised to false. Now that we
are doing the actual version handshake, the values of `fClient` and
`m_limited_node` are set during the handshake and cause the test to fail
if we do not set `dummyNode1.nServices` to a reasonable value
(NODE_NETWORK | NODE_WITNESS).

Miniscript support in output descriptors
Miniscript descriptors are defined under P2WSH context (either `wsh()`
or `sh(wsh())`).
Only sane Miniscripts are accepted, as insane ones (although valid by
type) can have surprising behaviour with regard to malleability
guarantees and resources limitations.
As Miniscript descriptors are longer and more complex than "legacy"
descriptors, care was taken in error reporting to help a user determine
for what reason a provided Miniscript is insane.

Merge bitcoin/bitcoin#25464: rpc: Reduce Univalue push_backV peak memory usage in listtransactions
fa8a1c0696 rpc: Fix Univalue push_backV OOM in listtransactions (MacroFake)

Pull request description:

  Related to, but not intended as a fix for #25229.

  Currently the RPC will have the same data stored thrice:

  * `UniValue ret` (memory filled by `ListTransactions`)
  * `std::vector<UniValue> vec` (constructed by calling `push_backV`)
  * `UniValue result` (the actual result, memory filled by `push_backV`)

  Fix this by filling the memory only once:

  * `std::vector<UniValue> ret` (memory filled by `ListTransactions`)
  * Pass iterators to `push_backV` instead of creating a full copy
  * Move memory into `UniValue result` instead of copying it

7a45c33d1f Introduce generic 'Result' class (furszy)

Pull request description:

  Based on a common function signature pattern that we have all around the sources:
  ```cpp
  bool doSomething(arg1, arg2, arg3, arg4, &result_obj, &error_string) {
      // do something...
      if (error) {
          error_string = "something bad happened";
          return false;
      }

      result = goodResult;
      return true;
  }
  ```

  Introduced a generic class `BResult` that encapsulate the function boolean result, the result object (in case of having it) and, in case of failure, the string error reason.

  Obtaining in this way cleaner function signatures and removing boilerplate code:

  ```cpp
  BResult<Obj> doSomething(arg1, arg2, arg3, arg4) {
      // do something...
      if (error) return "something bad happened";

      return goodResult;
  }
  ```

  Same cleanup applies equally to the function callers' side as well. There is no longer need to add the error string and the result object declarations before calling the function:

  Before:
  ```cpp
  Obj result_obj;
  std::string error_string;
  if (!doSomething(arg1, arg2, arg3, arg4, result_obj, error_string)) {
      LogPrintf("Error: %s", error_string);
  }
  return result_obj;
  ```

  Now:
  ```cpp
  BResult<Obj> op_res = doSomething(arg1, arg2, arg3, arg4);
  if (!op_res) {
      LogPrintf("Error: %s", op_res.GetError());
  }
  return op_res.GetObjResult();
  ```

  ### Initial Implementation:

  Have connected this new concept to two different flows for now:

  1) The `CreateTransaction` flow. --> 7ba2b87c
  2) The `GetNewDestination` flow. --> bcee0912

  Happy note: even when introduced a new class into the sources, the amount of lines removed is almost equal to added ones :).

  Extra note: this work is an extended version (and a decoupling) of the work that is inside #24845 (which does not contain the `GetNewDestination` changes nor the inclusion of the `FeeCalculation` field inside `CreatedTransactionResult`).

Merge bitcoin-core/gui#627: Apply translator comments to reset options confirmation dialog
d5c141f221 qt: apply translator comments to reset options confirmation dialog (Jarol Rodriguez)

Pull request description:

  This is a followup to #617. Because the strings were being concatenated, we can not apply translator comments to all of the revelant strings. This can be tested by applying the following diff to current master and running `make translate`; then check the resulting diff:

  ```diff

               QMessageBox::Yes | QMessageBox::Cancel, QMessageBox::Cancel);
  ```

  To apply the above translator comments, what we want to do instead is have a variable in which the translatable strings are appended to using the [QString append function](https://doc.qt.io/qt-5/qstring.html#append).

  When you run `make translate` with this PR, you will see the translator comments properly applied, as shown below:
