yang: redefine nexthop operational model
Separate out nexthop config and operational models.
nexthop-group config model has list of nexthop-groups
where else operational nexthop group is single entity
underneath list of nexthops.
The common code is fectored into grouping to use among
config and operational model.
nexthop operational model caters to RIB operational model.

sharpd,zebra: unicast support for zapi messages
Distinguish between unicast and broadcast opaque messages
in zebra handler code. Add cli and internal api changes to
have sharpd send unicast opaque messages. Add opaque cli
commands to the sharp user doc.
before the last commit, it was possible under some
circumstances to call isis_circuit_af_set on a circuit
with a NULL area, e.g. if the circuit was deconfigured
due to a validation error. While this should not happen
now, let's add an explicit check to avoid crashing if
a regression is introduced.

if we are not able to bring a circuit up due to some config
issue, e.g. a low MTU compared to the area lsp-mtu, we should
not remove the configuration, as this will push out of sync
with the YANG state and create more issues down the line.
Instead, keeping the circuit state at C_STATE_CONF should be
sufficient.
For the specific case of the MTU mismatch above, this also means
that when we receive a new IF_UP_FROM_Z when the MTU is changed
we will be able to bring the circuit up as we should.

lib: fix prefix list installation
Based on the function `prefix_list_entry_add` and
`prefix_list_entry_delete` it was created two functions to replicate
its functionality without the assumption we are always alocating a new
prefix list entry.
Since the prefix list entry is stored in the YANG private data
structures, we want to avoid the allocation/free of memory that is
hold by the schema.
Every time a prefix list entry values change we must call
`prefix_list_entry_update_start` to uninstall the entry from prefix
list internal structures and then call
`prefix_list_entry_update_finish` to put them back.
The variable `installed` in the prefix list entry tracks the
installation status of the internal structure. It is possible that a
user unconfigures or forgets to add a `prefix` value and so we can't
install the entry until then.

bgpd: Actually find the sequence number for `bgp extcommunity-list...`
The code in the bgp extcommunity-list function was using
argv_find to get the correct idx. The problem was that
we had already done argv_finds before and idx was non-zero
thus having us always set the seq pointer to what was last
looked up. This causes us to pass in a value to the
underlying function and it would just wisely ignore it
causing a seq number of 0.
We would then write this seq number of 0 and then immediately
reject it on read in again. BOO!
Actually handle argv_find the way it was meant to be.
