Use different approach for filling large datasets to userspace:

Instead of trying to allocate bing contiguous chunk of memory,
use intermediate-sized (page size) buffer as sliding window
reducing number of sooptcopyout() calls to perform.

This reduces dump functions complexity and provides additional
layer of abstraction.

User-visible api consists of 2 functions:
ipfw_get_sopt_space() - gets contigious amount of storage (or NULL)
and
ipfw_get_sopt_header() - the same, but zeroes the rest of the buffer.
