fa3e0da06b policy: Treat taproot as always active (MarcoFalke)
Pull request description:
Now that taproot is active, it can be treated as if it was always active for policy for the next major release. This simplifies the code and changes two things:
* Importing `tr` descriptors can be done before the chain is fully synced. This is fine, because the wallet will already generate `tr` descriptors by default (regardless of the taproot status) after commit 47fe7445e7.
* Valid taproot spends won't be rejected from the mempool before taproot is active. This is strictly speaking a bugfix after commit 47fe7445e7, since the wallet may generate taproot spends before the chain is fully synced. For example, a slow node or a purposefully offline node. Currently, the wallet needs the mempool to account for change. See https://github.com/bitcoin/bitcoin/issues/11887.
A similar change was done for segwit v0 in https://github.com/bitcoin/bitcoin/pull/13120 .
This effectively reverts commit c5ec0367d7.

0e0f4fdd89 multiprocess: Add interfaces::Node::broadCastTransaction method (Russell Yanofsky)
Pull request description:
This fixes a null pointer crash in the bitcoin-gui PSBT dialog. The bitcoin-gui interfaces::Node object has a null NodeContext pointer, and can't broadcast transactions directly. It needs to broadcast transactions through the bitcoin-node process instead.

ad085f9ba1 multiprocess: Delay wallet client construction (Russell Yanofsky)
Pull request description:
Delay wallet client construction until after logging, thread and other init for two reasons:
- More responsive multiprocess GUI startup. When bitcoin-gui is started this moves the call from bitcoin-gui to bitcoin-node that spawns bitcoin-wallet off of the GUI event thread and onto the background GUI init executor thread.
- Avoids feature_logging.py test failures with bitcoin-node by making bitcoin-wallet logging start after bitcoin-node logging starts,
because the tests are not written to handle the bitcoin-wallet logging init code running first.
This partially reverts commit b266b3e0bf, moving wallet client creation back to the place it was located before.

7e88f61b28 multiprocess: Make interfaces::Chain::isTaprootActive non-const (Russell Yanofsky)
Pull request description:
`interfaces::Chain` is an abstract class, so declaring the method const would be exposing internal implementation details of subclasses to interface callers. And specifically this doesn't work because the multiprocess implementation of the `interfaces::Chain::isTaprootActive` method can't be const because IPC connection state and request state is not constant during the call.

Add interfaces::ExternalSigner to let signer objects be passed between

e4709c7b56 Start using init makeNode, makeChain, etc methods (Russell Yanofsky)
Pull request description:
Use `interfaces::Init::make*` methods instead of `interfaces::Make*` functions, so interfaces can be constructed differently in different executable without having to change any code. (So for example `bitcoin-gui` can make an `interfaces::Node` pointer that communicates with a `bitcoin-node` subprocess, while `bitcoin-qt` can make an `interfaces::Node` pointer that controls node code in the same process.)

5c5d0b6264 Add FoundBlock.found member (Russell Yanofsky)
Pull request description:
This change lets IPC serialization code handle FoundBlock arguments more simply and efficiently. Without this change there was no way to determine from a FoundBlock object whether a block was found or not. So in order to correctly implement behavior of leaving FoundBlock output variables unmodified when a block was not found, IPC code would have to read preexisting output variable values from the local process, send them to the remote process, receive output values back from the remote process, and save them to output variables unconditionally. With FoundBlock.found method, the process is simpler. There's no need to read or send preexisting local output variable values, just to read final output values from the remote process and set them conditionally if the block was found.
