when a path has IPv4 NLRI and IPv6 nexthop, handle it in MPBGP manner.
(use mp-reach-nlri path attribute instead of nexthop path attibute)

RFC4760 says:
An UPDATE message that contains the MP_UNREACH_NLRI is not required to
carry any other path attributes.

Fix a bug that gobgp creates a wrong update message from path having
MP_REACH with multiple NLRIs. gobgp always allocates a path per NRLI
(that is, multiple paths from an update message having MP_REACH with
multiple NLRIs).

post-policy code creates paths from bgp update and then create the
message from the modified paths. MP_UNREACH needs to be handled
diffently.

Actually comapring all the attributes to see if packing NLRIs. It
takes long but gobgpd sends minimum messages.

With this patch, bobgpd packs multiple NLRIs into one BGP update
message (IOW, multiple paths into one update message).
We do only with ipv4 since we could have lots of routes. If you don't
have lots, it's not worth having the complicated logic for such route
families.

this patch fixes the wrong behavior shown below
$ gobgp global rib add 10.0.0.0/24
$ gobgp global rib del 10.0.0.0/24
$ gobgp global rib
Network Next Hop AS_PATH Age Attrs
*> 10.0.0.0/24 0.0.0.0 65000 00:05:48 [{Origin: IGP}]
since we used to compare path's source by PeerInfo's pointer, locally
originated routes is considered as a different route even if they have
same prefix.
this patch introduce Equal() method to compare PeerInfo's content and
fix this wrong behavior.

table_manager.go clones withdraw path before passing it to peer.go
clone() doesn't clone pathattributes. This patch adds a helper
funciton to clone PathAttributes to message.go (it is used by
createing BGPUpdate message to withdraw ipv6. later it will be used
for 2 byte AS peer).
