====================
Convert network timestamps to be y2038 safe

Introduction:

The series is aimed at transitioning network timestamps to being
y2038 safe.
All patches can be reviewed and merged independently.

Socket timestamps and ioctl calls will be handled separately.

Thanks to Arnd Bergmann for discussing solution options with me.

Solution:

Data type struct timespec is not y2038 safe.
Replace timespec with struct timespec64 which is y2038 safe.

Changes v1 -> v2:
  Move and rename inet_current_time() as discussed
  Squash patches 1 and 2
  Reword commit text for patch 2/3
  Carry over review tags
