This commit adds an empty common altp2m.c and altp2m.h file to be added to
in later commits. Creating a commit with just the empty file additions
makes it easier to reorder later commits which add to these files.

This commit can be squashed into the first commit which actually adds
something to altp2m.c/altp2m.h for the actual submission if that would be
preferred.

This is commit 1/8 of the preparation phase.
