api/Grpc is too general for package/service name.
rename them to gobgpapi/GobgpApi.

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

This reverts commit 51494759aded7098e151869e66dd5b2c4d96ecfd.
gobgpd still sends too more updates rather than Quagga. Revert this.

we can't parse Path.nlri field (whose type is []byte) without route family.

Without hurting the performance (the latency) much, GetBestPathList()
tries to sort Paths in the order that many routes could be packed into
one update message.
I did an experiment that the full routes are pushed to gobgpd (via
mrt), then another peer connects to gobgpd.
Without this patch, gobgpd sends 550,958 update messages to another
peer.
With this patch, gobgpd sends 250,606 update messages.

With experiments about the full routes, we hit the limit. Let's remove
it.

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.

When gobgp originates a route, the generated route had incorrect
as-path. this patch fix this bug.
Scenario test is also added to check this.

if we add same path multiple times by the following gobgp cli commands,
$ gobgp global rib add 10.0.0.0/24
$ gobgp global rib add 10.0.0.0/24
$ gobgp global rib add 10.0.0.0/24
current implementation sends multiple update messages to peers
even through the content of the path is same.
This is due to the shallow equivalence checking.
This patch checks paths' equivalence deeper by adding Equal() method to Path.
