Lexi Winter 50ecbc5142 libipsec: make const-correct
- add const to the appropriate places in the libipsec public API and the
  relevant internal functions needed to support that.

- replace caddr_t with c_caddr_t in ipsec_dump_policy()

- update the ipsec_dump_policy manpage to use c_caddr_t (this manpage
  was already wrong as it had "char *" instead of caddr_t previously).

While here, update pfkeyv2.h to not cast away const in the PFKEY_*()
macros.

This should not cause any ABI changes as the actual types have not
changed.
