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().

Jansi has moved to https://github.com/jline/jline3 under org.jline.jansi which is used by Maven 4.x.
This effectively breaks build-tools Maven Plugins:
