Re: Convert *GetDatum() and DatumGet*() macros to inline functions

Tom, Robert,

> Yeah, I don't see a reason to back-patch a change like this

Maybe we should consider backporting at least 0001 patch, partially
perhaps? I believe if fixes pretty cursed pieces of code, e.g:

```
             pg_cryptohash_ctx *context =
-            (pg_cryptohash_ctx *) PointerGetDatum(foundres);
+            (pg_cryptohash_ctx *) DatumGetPointer(foundres);
```

This being said, personally I don't have a strong opinion here. After
all, the code works and passes the tests. Maybe I'm just being a
perfectionist here.
