Deprecating .gdbinit files requires a NEWS entry.
[But maybe that's in a later patch.]

And are we *really* sure we want to deprecate them?
I don't read every thread (and forget half I do read :-() so I may
have missed a high level decision.

While I realize you might be trying to avoid adding another option,
combining warn on/off with auto-load on/off is a bit odd.  Is it
possible to look at this differently and have the warning apply to
more than just local-gdbinit (thus being a more useful option and thus
being less of a pain to add)?
E.g., a warning for using deprecated features or some such.
[Or maybe we want a warning for each such feature, dunno.]

This assumes absence of padding.
