We are dangerously teetering every time an option to add "just one more"
thing to the CD is committed to being unable to fall below the 685MB
size (which I understand is what FreeBSDMall needs for the CDs they
produce).

So, as our src/ and ports/ trees grow, the room we have left is
shrinking fast.  I think it is not feasible to ship the tests on the CD,
but I do agree they can be shipped on the DVD.

Julio has submitted a review request for this to make a tests.txz
distribution, which can then be excluded for the bootonly.iso and
disc1.iso, but kept for the dvd.iso.

I am building a test release build with this change now, but I am aware
of one immediate problem that will be encountered - if we default
WITH_TESTS=1, the running userland on the bootonly.iso and disc1.iso
(used for the installer) will also include the tests.

This is because we do not evaluate the value of WITH_TESTS=, but only
that it is defined.  This is also a problem for the debug.txz with
WITH_DEBUG_FILES=1 for the buildworld/buildkernel, but
WITHOUT_DEBUG_FILES=1 for the bootonly.iso and disc1.iso creation,
because we cannot set both.

Some of the later commits to a projects/ branch to work on allowing the
debug.txz to be fetched from FTP (or via the netinstall) illustrates the
problem and some very hackish workarounds I have tried.
