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.
