[dpdk-dev] [PATCH] Introduce travis builds for github repositories

[Michael Santana <msantana@redhat.com>]

GitHub is a service used by developers to store repositories.  GitHub
provides service integrations that allow 3rd party services to access
developer repositories and perform actions.  One of these services is
Travis-CI, a simple continuous integration platform.

This is a simple initial implementation of a travis build for the DPDK
project.  It doesn't require any changes from individual developers to
enable, but will allow those developers who opt-in to GitHub and the
travis service to get automatic builds for every push they make.

Additionally, the travis service will send an email to the test-report
list informing anyone interested in the automated build (including a
result).
