During route processing in zebra, Zebra will create a nexthop
group that matches the nexthops passed down from the routing
protocol. Then Zebra will look to see if it can re-use a
nhe from a previous version of the route entry( say a interface
goes down ). If Zebra decides to re-use an nhe it was just dropping
the route entry created. Which led to nexthop group's that had
a refcount of 0 and in some cases these nexthop groups were installed
into the kernel.
Add a bit of code to see if the returned entry is not being used
and it has no reference count and if so, properly dispose of it.

Currently when re-evaluating an aggregate route, the full attribute of
the aggregate route is not compared with the existing one in the BGP
table. That can result in unnecessary churns (un-install and then
install) of the aggregate route when a more specific route is added or
deleted, or when the route-map for the aggregate changes. The churn
would impact route installation and route advertisement.
The fix is to apply the route-map for the aggregate first and then
compare the attribute.
Here is an example of the churn:
debug bgp aggregate prefix 5.5.5.0/24
!
route-map set-comm permit 10
set community 65004:200
!
router bgp 65001
address-family ipv4 unicast
redistribute static
aggregate-address 5.5.5.0/24 route-map set-comm
!
Step 1:
ip route 5.5.5.1/32 Null0

Step 2:

In zlog_5424_cycle(), struct zlt_5424 *zlt only points to valid memory when
the passed file descriptor is >= 0 (and passing -1 seems to be a supported
use case). So we shouldn't try to compute the address of its zt member when
zlt is NULL.

When changing the log threshold (prio_min) using zlog_5424_apply_meta(), try
to open the log destination using zlog_5424_open() if we haven't done so
before. Without this, we might never open the destination at all, because
when zlog_5424_apply_dst() gets called (which so far was the only initial
caller of zlog_5424_open()), chances are that prio_min is still at its
initial value of ZLOG_DISABLED, causing it to skip the call to
zlog_5424_open().

Don't over-allocate syscaps in zcaps2sys(): This is just a single struct
(pset_t) with a count and a pointer to an array of capabilities, not an
array. So only allocate a single pset_t, not num copies of it.
The allocation size of syscaps->caps then needs to be based on the number of
Linux capabilities (count), but that is already handled properly a few lines
below.
Note that this fix is mostly cosmetic and for correctness. There was no
potential for memory corruption, because num is guaranteed to be nonzero. So
at least the one required pset_t was always allocated (but potentially much
more).
