ddt: compare keys, not entries

Browse Source 
We're about to have different kinds of things that we'll compare on key,
so generalise this function to support that.

(It actually worked fine because of the way the casts work out, but it
requires the key to be at the start of the object so the cast through
ddt_entry_t works, and even then it reads strangely for anything that's
not a ddt_entry_t).
