Separate owipcalc in client and lib part. Owipcalc brings a lot of nice
functionality with it, e.g. parsing and calculating prefixes.

owipcalc: fix contains not respect default route2021-01-23T16:48:18ZNick Hainke2021-01-23T12:48:11Zurn:sha1:e974acaac78d8b90bd9e5cbd81010593ec725cbb
In IPv4 the default route can be written as
0.0.0.0/0
In IPv6 the default route can be written as
::/0
If u try
owipcalc 0.0.0.0/0 contains 1.1.1.1
or
owipcalc ::/0 contains ::1
owipcalc will respond with 0 meaning that the "default prefixes" do not
contain the routes.
That is why we check now for 0 prefix.
Furthermore, if the prefix is 0, i will be 16. We will access a negative
array entry in the line:
uint8_t net1 = x->s6_addr[15-i] & m;
Divide by % 16 to prevent i becoming 16:
uint8_t i = ((128 - a->prefix) / 8) % 16;

owipcalc: import from base2021-01-22T16:12:53ZAdrian Schmutzler2021-01-22T16:12:53Zurn:sha1:ee75bd5a8f4780aefaec3e7a8075b637899cf050
This is a helpful utility, but it does not have any dependencies
in base repository. Move it to packages feed.
