When additional path index are in use there must be more remaining data bytes.
Therefore we return only 1 when the len is greater 1.

BGP-LS is just a collector of IGP link state information. Some
fields are encoded "as-is" from the IGP, hence in order to dissect
them properly we must be aware of their origin, e.g. IS-IS or OSPF.
So, *before* dissecting LINK_STATE attributes we must get the
'Protocol-ID' field that is present in the MP_[UN]REACH_NLRI
attribute. The tricky thing is that there is no strict order for path
attributes on the wire, hence we have to keep track of 1) the
'Protocol-ID' from the MP_[UN]REACH_NLRI and 2) the offset/len of
the LINK_STATE attribute. We store them in per-packet proto_data and
once we got both we are ready for the LINK_STATE attribute dissection.

They're not just addresses, they also include a mask length for IPv4 and
a prefix length for IPv6. Rename them appropriately.
Rename the old ipv4_addr_and_mask() and ipv6_addr_and_mask() to reflect
that 1) they fetch data from a tvbuff and 2) *don't* fetch the mask
length or prefix length, those lengths are passed as arguments to
indicate how many bytes worth of address to fetch.

It ends up dragging in libwireshark headers, which programs not linking
with libwireshark shouldn't do. In particular, including
<epan/address.h> causes some functions that refer to libwireshark
functions to be defined if the compiler doesn't handle "static inline"
the way GCC does, and you end up requiring libwireshark even though you
shouldn't require it.
Move plurality() to wsutil/str_util.h, so that non-libwireshark code can
get it without include epan/packet.h. Fix includes as necessary.
