CLI: dependency reduction

[barchetta]

Remove the remaining third party dependencies:

1. jansi-1.18.jar
2. compiler-0.9.6.jar

[romain-grecourt]

For Jansi there are two distinct usages:

• org.fusesource.jansi.Ansi ansi escapes constants, this should be fairly simple to rewrite.
• org.fusesource.jansi.AnsiConsole to install System.out and System.err.

The installed PrintStream are system specific and respond to various system properties which are used in build-tools. Overall this is fairly complicated, although removing Jansi with our own mechanism would simplify this area.

AnsiConsole uses JNI to detect if STDOUT or STDERR are TTY.

The native code is provided for 7 platforms: linux32, linux64, windows32, windows64, freebsd32, freebsd64, osx. It is mostly a wrapper around isatty from the standard C library + workaround for windows.

We may be able to just use System.console() != null or System.console().isTerminal().
