rippled (XRP Ledger server) Version 2.0.0-b1 (beta)

This is a beta for the next release.

Highlights:

• Support for XLS-38 XChainBridge (side chains) (#4292)
• Several changes to improve performance

When finalized, the next stable release of rippled is expected to be the last release for 2023 (given the holidays in Nov/Dec). The major version is bumped for the following reasons:

• api_version 2 general availability
  • This api_version is not available yet (except in beta, requiring a configuration change), but it will be in the next release.
• Notable performance improvements in TPS (transactions per second).
• XLS-38 sidechains support
  • This is a large change and adds significant new functionality to the protocol.
• Lastly, many aspects of the code have been refactored and changed since the previous major version bump.

(Note that the replacement for getting and setting thread name (#4312) was reverted, so it is not in this release.)
