The daemon API is built as a Swift module called ServalDNA. The new CliContext class allows easy implementation of CLI output using Swift code. The new CliContextFile subclass is the obvious first implementation, equivalent to cli_stdio.c. The 'servaldswift' executable now uses CliContextFile to print its CLI output to standard output. The new delegated log output support constructs each log line in a buffer and prints it by calling the delegate's 'print' function at end-of-line. The 'servaldswift' executable now provides a log output delegate in Swift that simply prints to standard error, replacing log_output_console.o, which is omitted from its link.
