The owipcalc tool provides an "add" algorithm which can be used
to concateneted IPv6 addresses from prefix and suffix.
Since it's available upstream and our string manipulation is ugly,
let's replace our IP concatenation with that tool. The package
consists of a single .c file with about 1000 lines resulting in
about 4 kB for the ipk package.
This patch does _not_ introduce any conceptual changes yet. Thus,
the "wrong" IPv6 prefix from KeyXchange will be expected in the
same format, it is just healed for the new code for now.
The change allows to get rid of some bloat, i.e. some quite trivial
custom functions on the way. This also drops the ipTidyColon()
function, as owipcalc seems to return the collapsed version by default.

Previously, IPv6 addresses were constructed by reading from
the device config file in the function. To have more options,
it is better to use the address itself as parameter.
By this way we can decide what we use for getting the MAC when
calling.

This puts the code for creating IPv6 addresses from MAC
address and EUI into functions, so it can be reused.
This should be particularly helpful if code is rewritten later.
