stddef: Introduce __TRAILING_OVERLAP()
Introduce underlying __TRAILING_OVERLAP() macro to let callers apply
atributes to trailing overlapping members.
For instance, the code below:
| struct flex {
| size_t count;
| int data[];
| };
| struct {
| struct flex f;
| struct foo a;
| struct boo b;
| } __packed instance;
can now be changed to the following, and preserve the __packed
attribute:
| __TRAILING_OVERLAP(struct flex, f, data, __packed,
| struct foo a;
| struct boo b;
| ) instance;
