Use single VM in .travis.yml to speed-up launching builds. Container are launched in parallel threads.

The output of each thread is saved to a log. All of them are printed in order, after all the threads have finished.
Shared ANSI color codes between libraries/vendors and dist/linux. The common file to be sourced is dist/ansi_color.sh
