Heimdal's HDB plugin interface, and hence Samba's KDC that depends upon it, doesn't work on 32-bit builds due to structure fields being arranged in the wrong order. This problem presents itself in the form of segmentation faults on 32-bit systems, but goes unnoticed on 64-bit builds thanks to extra structure padding absorbing the errant fields. This commit reorders the HDB plugin structure fields to prevent crashes and introduces a common macro to ensure every plugin presents a consistent interface.
