Andrew Bettison a79156c4d0 Add Swift daemon API, use in 'servaldswift'
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.
