of dbmmodule dynamically by default (otherwise it can pull in
dependencies with libdb that croak pybsddb3). This change moves the
Setup line for dbmmodule to Setup.config.in.
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.
