MarcoFalke ba15ab4990 Merge bitcoin/bitcoin#22218 : multiprocess: Add ipc::Context and ipc::capnp::Context structs

3e33d170cc Add ipc::Context and ipc::capnp::Context structs (Russell Yanofsky)

Pull request description:

  These are currently empty structs but they will be used to pass some function and object pointers from bitcoin application code to IPC hooks that run, for example, when a remote object is created or destroyed, or a new process is created.

  This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10). The commit was first part of larger PR #10102.

Internal c++ interfaces

The following interfaces are defined here:

Chain — used by wallet to access blockchain and mempool state. Added in #14437, #14711, #15288, and #10973.
ChainClient — used by node to start & stop Chain clients. Added in #14437.
Node — used by GUI to start & stop bitcoin node. Added in #10244.
Wallet — used by GUI to access wallets. Added in #10244.
Handler — returned by handleEvent methods on interfaces above and used to manage lifetimes of event handlers.
Init — used by multiprocess code to access interfaces above on startup. Added in #19160.
Ipc — used by multiprocess code to access Init interface across processes. Added in #19160.

The interfaces above define boundaries between major components of bitcoin code (node, wallet, and gui), making it possible for them to run in different processes, and be tested, developed, and understood independently. These interfaces are not currently designed to be stable or to be used externally.
