include: fix missing definitions in <cache.h>/<headers.h>

The headers should be self-contained so they can be included in any
order. With exception of <nft.h>, which any internal header can rely on.

Some fixes for <cache.h>/<headers.h>.

In case of <cache.h>, forward declare some of the structs instead of
including the headers. <headers.h> uses struct in6_addr.
