dfilter: Add support for universal quantifiers
Adds the keywords "any" and "all" to implement the quantification
to any existing relational operator.
Filter: all tcp.port in {100, 2000..3000}
Syntax tree:
0 ALL TEST_IN:
1 FIELD(tcp.port)
1 SET(#2):
2 FVALUE(100 <FT_UINT16>)
2 FVALUE(2000 <FT_UINT16>) .. FVALUE(3000 <FT_UINT16>)
Instructions:
00000 READ_TREE tcp.port -> reg#0
00001 IF_FALSE_GOTO 5
00002 ALL_EQ reg#0 === 100 <FT_UINT16>
00003 IF_TRUE_GOTO 5
00004 ALL_IN_RANGE reg#0 in { 2000 <FT_UINT16> .. 3000 <FT_UINT16> }
00005 RETURN
