2.0.0-rc2

Changed

• The entry point for creation of C++ apps is now make_user_endpoints(). The old entry point get_rpc_handler() has been removed (#3562). For an example of the necessary change, see this diff of the logging sample app (#3562).
• Failed recovery procedures no longer block subsequent recoveries: .recovery ledger files are now created while the recovery is in progress and ignored or deleted by nodes on startup (#3563).
• Corrupted or incomplete ledger files are now recovered gracefully, until the last valid entry (#3585).
• The CCF public API is now under include/ccf, and all application includes of framework code should use only these files.

Removed

• get_node_state() is removed from AbstractNodeContext. The local node's ID is still available to endpoints as get_node_id(), and other subsystems which are app-visible can be fetched directly (#3552).

Fixed

• Nodes no longer crash at start-up if the ledger in the read-only ledger directories (ledger.read_only_directories) is ahead of the ledger in the main ledger directory (ledger.directory) (#3597).
