This adjusts the lldb-dap listening mode to accept multiple clients. Each client initializes a new instance of DAP and an associated `lldb::SBDebugger` instance. The listening mode is configured with the `--connection` option and supports listening on a port or a unix socket on supported platforms. When running in server mode launch and attach performance should be improved by lldb sharing symbols for core libraries between debug sessions.
