i just said it like 2 times already that i think this destck() and the
result serveraddrs() check is bogus and is the source of all this
confustion.

the "curdest" is handled as an end pointer in the rest of the code.

its where you start adding stuff, and after writing it, you increment
it to the next element. so it always points past the last valid element.
this is just idiomatic c code.

serveraddrs() should take a start index (current count) and return a
count. and at the beginning check if the start index is already the
maximum size of the dest array. this makes the most sense and is not
hard to understand.
