This patch is a functionality modification to lxdialog to add support
for an "Abort" button in *addition* to the standard "Yes" and "No"
buttons on the "yesno" dialog. The intended purpose of this patch is to
give users the ability to abort their last requested action.

Actually it's already possible to abort the dialog by pressing Esc. I
don't mind the abort button, but please match the Esc behaviour and return
-1.

Advise taken. Personally, I don't like "magic numbers", so I'd prefer
to return an enumerated type (DIALOG_RESULT), if you don't mind.
