Make javac.py output colorful

Make javac.py output colorful

This highlights warnings in yellow, errors in red(ish), and the ^ marker
in blue.

Adds stdout_filter and stderr_filter to build_utils.CheckOutput. If the
caller handled this themselves they would need to print stdout/stderr
themselves and modify the value stored in the ProcessCalledException.

warning: [serial] serializable class

serialVersionUID
personally, I would probably drop the example lines, but if you want to keep
them, then I would add a comment line above them to make it easier to mentally
parse (i.e. Example warning output line:)

FYI, you should always use `sys.path.insert(0, …`. Else if the user has a module
installed locally it will get precedence over the bundled one, and the installed
version might not be api-compatible with the bundled one.
