Edits to help support repo:onf-make as a git submodule.

transition.mk
-------------
  o Basic bridge logic for transition to repo:onf-make.
  o Include costs.mk and virtualenv targets.
  o Conditional include.mk logic to inline into Makefile
    appended at the end.

makefiles/detect
----------------
  o WIP
  o Add detection logic to enable makefile features based on extension.
  o Targets and logic can be loaded on demand based on available source.
    VS kitchen sink/load everything that happens now.
