stats: remove offsets on vpp side
Represent pointers directly in shared memory and require clients to adjust for shared memory segment being mapped at different base address. Deprecated: stat_segment_pointer() / stat_segment_offset() Added: stat_segment_adjust() Bumped the stat segment version to 2. Type: refactor Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I33e756187b8903b45dcd353e6c1a101b7a4acb79
