[PATCH v3 58/74] qom: Make type checker functions accept const pointers |

qualifiers from their arguments. Keep this behavior in the
macros generated by DECLARE_*CHECKER* by now.

Changes v1 -> v2:
* Removed note about _Generic from commit message, because it
won't be possible to do what I was planning without manual
