make packages

[rakslice]

I didn't bother going down the road i did in the aix ver of these scripts by make installing first in a DESTDIR or similar, because I didn't do anything further with that there.

But svr4 has a packaging system.

• Figure out if there's a way to properly create packages, or ham up something with pkgtrans.
• Get packages installing to a DESTDIR or similar instead of the final target
• Put it together

This is a work in progress in branch packaging.

I've implemented the necessary changes in build.inc and finished a first pass through the individual build scripts.

I mostly just need to update the CD image. My plan is to update it with the package building version, bootstrap a vm with it and do a good build of the packages, and then transfer the packages out and put them on the CD also. Then I will change it so the most obvious installation script will just install the packaged version, but all the scripts and sources will be there if you want to built from source instead.

I should update the go script to symlink out more things that need more space (e.g. /var.tmp); maybe I'll specify an actual VM disk size needed to to a default fresh install and get through the build. Other follow on stuff:

• Measure the package installation disk requirements
• Script the package build install time test for files left behind in the prefix (that may have been installed directly to the final location, ignoring the DESTDIR or similar)
• Script checking packages for files outside of the parts of the file tree we expect them in (by scanning the prototype files)

Moved the other nice to have bullet points there out to a separate issue.
