Update the build structures to automatically detect the presence of BSD db,
including the proper name of the header file to include.  Has all the
expected niceties associated with yet-more-configure-options.  ;)

This checkin includes changes for non-generated files only; subsequent
checkin will catch those.

This is part of SourceForge patch #101272.
