Subject: Cleanup: Alembic: use pointers instead of references when passing
 progress variables

Using pointers instead of references when passing progress variables
makes the C++ code more in line with the C code (as it doesn't transform
pointer parameters to reference parameters). Also makes it easier to
spot when a common Blender pattern is implemented incorrectly (fix will
be in the next commit).
