crda: relicense under copyleft-next-0.3.0

I'm relicensing CRDA to copyleft-next-0.3.0. The original
motivation was to help with the BSD family but they are not
using any of this software and as this software grows I'd
like to ensure we use the best free software license

Fontana's work on copyleft-next is great and has good
community traction. At this point development for
copyleft-next has slowed down as copyleft-next-0.3.0
is already a good, usable alternative to GPLv2 and GPLv3.

A few notes:

  * With copyleft we don't have to specify 'at your option
    any later version' since the license allows that by

  * Some folks might wonder if copyleft-next-0.3.0 is
    OSI OSD-conformant or FSF-free since neither of
    those bodies have examined the license officially,
    but note, although IANAL, that copyleft-next is
    outbound-compatible with GPLv2 and GPLv3
