Merge bitcoin/bitcoin#28170: p2p: adaptive connections services flags

Pull request description:

  Derived from #28120 discussion.

  By relocating the peer desirable services flags into the peer manager, we
  allow the connections acceptance process to handle post-IBD potential
  stalling scenarios.

  The peer manager will be able to dynamically adjust the services flags
  based on the node's proximity to the tip (back and forth). Allowing the node
  to recover from the following post-IBD scenario:
  Suppose the node has successfully synced the chain, but later experienced
  dropped connections and remained inactive for a duration longer than the limited
  peers threshold (the timeframe within which limited peers can provide blocks). In
  such cases, upon reconnecting to the network, the node might only establish
  connections with limited peers, filling up all available outbound slots. Resulting
  in an inability to synchronize the chain (because limited peers will not provide
  blocks older than the `NODE_NETWORK_LIMITED_MIN_BLOCKS` threshold).

Repository Tools

Developer tools

Specific tools for developers working on this repository. Additional tools, including the github-merge.py script, are available in the maintainer-tools repository.

Verify-Commits

Tool to verify that every merge commit was signed by a developer using the github-merge.py script.

Linearize

Construct a linear, no-fork, best version of the blockchain.

Qos

A Linux bash script that will set up traffic control (tc) to limit the outgoing bandwidth for connections to the Bitcoin network. This means one can have an always-on bitcoind instance running, and another local bitcoind/bitcoin-qt instance which connects to this node and receives blocks from it.

Seeds

Utility to generate the pnSeed[] array that is compiled into the client.

Build Tools and Keys

Packaging

The Debian subfolder contains the copyright file.

All other packaging related files can be found in the bitcoin-core/packaging repository.

MacDeploy

Scripts and notes for Mac builds.

Test and Verify Tools

TestGen

Utilities to generate test vectors for the data-driven Bitcoin tests.

Verify-Binaries

This script attempts to download and verify the signature file SHA256SUMS.asc from bitcoin.org.

Command Line Tools

Completions

Shell completions for bash and fish.
