cmsdk: Declare a parcelable header.

Browse Source 
- This change forces that a parcelable header is written as the
  first data positions in a parcel and defines a means to distinguish
  between old sdk class versions vs new ones to do proper unraveling
  of parcels.

Ticket: BAMBOO-152
Change-Id: I9cc762fe8a51cc527e85be7fe5de57e4613be019
