Minimize includes of unrelated public headers by networking headers.

Stop including sys/param.h, sys/types.h, stdint.h, inttypes.h,
stdio.h, and string.h from network-related headers.  This is done
separately from earlier patches because the network headers are extra
messy, and are also more likely to contain quirks inherited verbatim
from 4.xBSD than the bulk of our public headers.

Rose and NetROM are based on AX.25 so it makes practical sense for
netrose/rose.h and netrom/netrom.h to continue including netax25/ax25.h.

The only copies of ip_icmp.h and udp.h in the source tree are moved
from sysdeps/gnu to inet (after which there are no longer any netinet/
headers in sysdeps/gnu).

Much as sys/un.h needs to duplicate the prototype for strlen,
netinet/icmp6.h needs to duplicate the prototype for memset.  I am
open to better ideas on that front.
