segtree: only use prefix expressions for ranges for selected datatypes
It is uncommon to represent f.i. port number ranges as prefix expressions.
Introduce a datatype DTYPE_F_PREFIX flag to indicate that the preferred
representation of a range is a prefix and use it for segtree decomposition
to decide whether to use a range or prefix expression.
The ipaddr, ip6addr, mark and realm datatypes are changed to include the
DTYPE_F_PREFIX flag.
This fixes completely unreadable output in cases where the ranges are
representable as prefixes, f.i. in case of port number:
{ 0/6 => jump chain1, 0/5 => jump chain2, 0/4 => continue}
becomes:
{ 0-1023 => jump chain1, 1024-2047 => jump chain2, 2048-4095 => continue}
