Reuse standard sk, ip and ipv6 cookie init handlers where possible.

Avoid repeated open coding of the same logic.
Harmonize feature sets across protocols.
Make IPv4 and IPv6 logic more alike.
Simplify adding future new fields with a single init point.

Willem de Bruijn (7):
  tcp: only initialize sockcm tsflags field
  net: initialize mark in sockcm_init
  ipv4: initialize inet socket cookies with sockcm_init
  ipv4: remove get_rttos
  icmp: reflect tos through ip cookie rather than updating inet_sk
  ipv6: replace ipcm6_init calls with ipcm6_init_sk
  ipv6: initialize inet socket cookies with sockcm_init
