pimd,pim6d: Set RP to true if the address matches, ignore prefix-length
The API pim_rp_check_interface_addrs checks if the RP address matches
with the primary address then it returns true.
In case of PIMv4 this condition is true, therefore the router becomes RP.
But in case of PIMv6, this condition does not pass because primary address
for PIMv6 is link-local address.
Also PIMv4 allows secondary addresses to be used as RP
if it is a host route in case primary does not match.
Fixing it by only checking the configured
RP address with the interface address and ignoring the prefix
length since it does not matter.
In several places, we are getting the vrf structure using
vrf_lookup_by_name(). Again we are passing vrf->vrf_id to
pim_get_pim_instance() to get the pim_instance.
The API pim_get_pim_instance() again get the VRF structure using
vrf_lookup_by_id(). This is avoided in this PR.

bgpd: rename "struct bgp" variables in mplsvpn
The "struct bgp" variable names in the mplsvpn bgp code do not
explicitly say whether they refer to a source or destination BGP
instance. Some variable declarations are commented out with "from" and
"to" but this does not avoid confusion within the functions. The names
of "struct bgp" variables are reused in different functions but their
names sometimes refer to a source instance and sometimes to a
destination instance.
Rename the "struct bgp" variable names to from_bgp and to_bgp.

pimd: Correct the order of show json for interface traffic
"show ip pim interface traffic json" shows pruneTx first and then
pruneRx stats
where as
"show ip pim interface <ifname> json" shows pruneRx first and then
pruneTx stats.
Although the values are right but the display looks odd.
Making it same as other stats, first display Rx and then Tx.
API to verify static route was checking whether
router is installed with expected nexthop. In
this particular scenario we has same route as
Connected and Static both. In heavy loaded
system static routes was taking time to get
installed and API was doing the verification
on Connected route instead Static route.
Enhanced scripts to check only static routes.

bgpd: work around GCC/plugin shortcomings
The GCC extended printf format checking plugin runs into some GCC
shortcomings regarding casts on printf function parameters. While this
can be fixed with a small GCC patch, patching GCC is "nontrivial" to say
the least. Luckily, it happens that this is /almost/ not an issue for
the FRR source base.
Since we fix SA "misunderstandings" too, let's just fix places where the
format checking plugin runs into this limitation to keep things working
extra smoothly.
(It's not a huge effort either, these two spots in bgpd are the only
places that trigger the plugin limitation, and it's been "clean" before
that for more than a year if my memory is right.)
