Stephen J. Kiernan 4ac21b4f09 Prepare for network stack as a module
- Move cr_canseeinpcb to sys/netinet/in_prot.c in order to separate the
   INET and INET6-specific code from the rest of the prot code (It is only
   used by the network stack, so it makes sense for it to live with the
   other network stack code.)
 - Move cr_canseeinpcb prototype from sys/systm.h to netinet/in_systm.h
 - Rename cr_seeotheruids to cr_canseeotheruids and cr_seeothergids to
   cr_canseeothergids, make them non-static, and add prototypes (so they
   can be seen/called by in_prot.c functions.)
 - Remove sw_csum variable from ip6_forward in ip6_forward.c, as it is an
   unused variable.

* Network types.

* Internally the system keeps counters in the headers with the bytes
* swapped so that VAX instructions will work on them. It reverses
* the bytes before transmission at each protocol level. The n_ types
* represent the types with the bytes in ``high-ender'' order. Network
* byte order is usually referered to as big-endian these days rather
* than high-ender, which sadly invokes an Orson Scott Card novel, or
* worse, the movie.
