IPOS: Add Ericsson IPOS kernel packet header dissector
IPOS is the networking operating system used in Ericsson's SSR 8000, Router 6000, and SP routers, etc.. This change added the IPOS kernel packet header dissector. The change creates a new file for IPOS protocol named "packet-ipos.c". IPOS will register sub dissectors with the dissect table "sll_linux_dissector_table" for IPOS internal ethernet packet types. IPOS dissector also calls the existing REDBACK dissector.
