Synced with SVN for trusted build component fork started by Kristin Mead.
Moving forward, GitHub will be the central repo.
Added support for:
  - creating makefiles for build to PX4
  - shared variables (data subcomponents in AADL)
  - entrypoints to match Pat's conception of them.
Also fixed a variety of bugs.
