[PATCH v2 6/8] socket: Add SO_TIMESTAMP[NS]_NEW

From: Deepa Dinamani
Date: Tue Dec 11 2018 - 15:28:54 EST

Add SO_TIMESTAMP_NEW and SO_TIMESTAMPNS_NEW variants of
socket timestamp options.
These are the y2038 safe versions of the SO_TIMESTAMP_OLD
and SO_TIMESTAMPNS_OLD for all architectures.

Note that the format of scm_timestamping.ts[0] is not changed
in this patch.
