Qi Zhang Sept. 17, 2021, 11:02 a.m. UTC 
  Add new parser module which can parse a packet in binary
and generate information like ptype, protocol/offset pairs
and flags which can be used to feed the FXP profile creation
directly.

The patch added skeleton of the parser instance create and
destroy APIs:
ice_parser_create
ice_parser_destroy
