rules, check out the help for ./configure to see what's changed. Added
the beginnings of autoconf DGA support (it is detected properly though it
isn't yet complete---HAS_DGA isn't getting defined in config.h for some
reason..)
places in the various Makefile.in's. Having them all in the module root
like that may make it easy to make a change that affects everything all
at once but it's real bitch to try and maintain those files. They're all
gone now and we'll just have to maintain the seperate makefiles.
