The VMSTATE_STRUCT_VARRAY_UINT32 macro is intended to handle migrating a field which is an array of structs, but where instead of migrating the entire array we only migrate a variable number of elements of it. The VMSTATE_STRUCT_VARRAY_POINTER_UINT32 macro is intended to handle migrating a field which is of pointer type, and points to a dynamically allocated array of structs of variable size. We weren't actually checking that the field passed to VMSTATE_STRUCT_VARRAY_UINT32 really is an array, with the result that accidentally using it where the _POINTER_ macro was intended would compile but silently corrupt memory on migration. Add type-checking that enforces that the field passed in is really of the right array type. This applies to all the VMSTATE macros which use flags including VMS_VARRAY_* but not VMS_POINTER.
