Get rid of GIT__PRIVATE macro

Using it in the first place means something's wrong.
This patch replaces it with an internal header which
carries the previously "protected" code instead.

Internal source-files simply include "commit.h" and
they're done. The internal header includes the public
one to make sure we always use the proper prototype.
