lib: work around enum issue in old gcc
I'd like to keep the explicit check here, but since underlying type of
enum is implementation defined, theres some inconsistency using -Wall

lib: handle failure to change ifindex
This fixes a theoretical bug that could occur when trying to change an
ifindex on an interface to that of an existing interface. We would
remove the interface from the ifindex tree, and change the ifindex, but
when we tried to reinsert the interface, the insert would fail. It was
impossible to know if this failed due to the insertion / deletion macros
capturing the result value of the underlying BSD tree macros. So we
would effectively delete the interface.
Instead of failing on insert, we just check if the prospective ifindex
already exists and return -1 if it does.
Macros have been changed to statement expressions so the result can be
checked, and bubbled up.

sharpd: Allow sharpd to specify it's own routes for label changes
With the command using STR_SHARP, the sharp daemon is not allowed
to use it's own routes for label modification. Switching over
to STR_ZEBRA allows the sharp daemon to modify labels on any
route in the system, since there are no `ROUTE_ZEBRA` types.

In some places we log the interface but not the vfr the
interface is in. In others we only output the vrf id, which
can be difficult for human to read. This commit makes zebra

ospf6d: stop looping thru same Inter-Area Router LSAs
Processing loop uncovered when there are multiple ABRs also
acting as ASBRs into the same area in ospf6. The problem
was that when looking thru the list of Inter-area router
entries, if the current entry being processed matched, it
still merged next-hops and re-initiated the process. In
this fix, if the route/path matches and the next-hops also
match, there is no need to re-initiate the examine process.

for some reason, when issuing a 'no metric-style' command we were
setting the metric-style to narrow, even though the default is
actually wide. Use NULL to avoid similar problems in the future.
Likewise, the 'no is-type' command was still trying to implement
the old logic of applying a different default for the first area.
In practice this had no effect because the value would now be the
same in both cases, but it's better to remove useless code anyway.

lib: support replacement in the nexthop-group cli
Use more limited matching logic so that nexthops within a
nexthop-group are unique based only on vrf, type, and gateway.
Treat configuration of a nexthop that matches an existing
nexthop as a replace operation.
zebra should only check whether a get_chunk operation succeeded
when processing the response, rather than insde the get_chunk
call itself. Spllitting the request and response hooks was done
precisely to allow for asynchronous calls to an external label
manager; in this case, the requested chunk is not necessarily
going to be available at request time.

Yang constraints enforced by the northbound callbacks require that
the maximum lifetime be >= than (refresh interval + 300). When we are
moving from one config to another through frr-reload.py, we issue
a number of vtysh -c commands ('no lsp-refresh-interval level-1 500',
'no max-lsp-lifetime level-1 1000'), which reset these parameters to their
default values, respectively 900 and 1200. Depending on the actual
values in the current config, the order in which these commands are sent
might be the wrong one, in that we hit an invalid intermediate state and
make vtysh (and by extension frr-reload.py) return an error.
As a workaround, let's add a one-liner command that sets all these
inter-related parameters in one go, and make isisd display them as a
single line too, so that the diff will be computed as a single command.
The old individual commands are kept to ensure backwards compatibility.

bgpd: fix multiple bugs with cluster_list attrs
Multiple different issues causing mostly UAFs but maybe other more
subtle things.
- Cluster lists were the only attributes whose pointers were not being
NULL'd when freed, resulting in heap UAF
- When performing an insert into the cluster hash, our temporary struct
used for hash_get() was inconsistent with our hash keying and
comparison functions. In the case of a zero length cluster list, the
->length field is 0 and the ->list field is NULL. When performing an
insert, we set the ->list field regardless of whether the length is 0.
This resulted in the two cluster lists hashing equal but not comparing
equal. Later, when removing one of them from the hash before freeing
it, because the key matched and the comparison succeeded (because it
was set to NULL *after* the search but *before* inserting into the
hash) we would sometimes release the duplicated copy of the struct,
and then free the one that remained in the hash table. Later accesses
constitute UAF. This is fixed by making sure the fields used for the
existence check match what is actually inserted into the hash when
that check fails.
This patch also makes cluster_unintern static, because it should be.
