6lowpan: nhc: add other known rfc6282 compressions This patch adds other known rfc6282 compression formats to the nhc framework. These compression formats are known but not implemented yet. For now this is useful to printout a warning which compression format isn't supported.

net: 6lowpan: use array for find nhc id This patch will remove the complete overengineered and overthinking rb data structure for looking up the nhc by nhcid. Instead we using the existing nhc next header array and iterate over it. It works now for 1 byte values only. However there are only 1 byte nhc id values currently supported and IANA also does not specify large than 1 byte values yet. If there are 2 byte values for nhc ids specified we can revisit this data structure and add support for it.
