  Introduce GIT_CALLBACK macro to enforce cdecl
  
  Since we now always build the library with cdecl calling conventions,
  our callbacks should be decorated as such so that users will not be able
  to provide callbacks defined with other calling conventions.
  
  The `GIT_CALLBACK` macro will inject the `__cdecl` attribute as
  appropriate.
