Running `bgp_srv6l3vpn_to_bgp_vrf` and `bgp_srv6l3vpn_to_bgp_vrf2`
topotests with `--valgrind-memleaks` gives several memory leak errors.
This is due to the way SRv6 SIDs are removed in bgpd: when
an SRv6 locator is deleted/unset, all the SIDs allocated from that
locator are removed from the SRv6 functions list
(`bgp->srv6_functions`),but the memory allocated for the SIDs is not
freed.
This patch adds a call to `XFREE()` to properly free the allocated
memory when an SRv6 SID is removed.

Running `bgp_srv6l3vpn_to_bgp_vrf` and `bgp_srv6l3vpn_to_bgp_vrf2`
topotests with `--valgrind-memleaks` gives several memory leak errors.
This is due to the way FRR daemons pass local SIDs to zebra: to send a
local SID to zebra, FRR daemons call the `zclient_send_localsid()`
function.
The `zclient_send_localsid()` function performs the following sequence
of operations:
* create a temporary `struct nexthop`;
* call `nexthop_add_srv6_seg6local()` to fill the `struct nexthop` with
the proper local SID information;
* create a `struct zapi_route` and call `zapi_nexthop_from_nexthop()` to
copy the information from the `struct nexthop` to the
`struct zapi_route`;
* send the `struct zapi_route` to zebra through the ZAPI.
The `nexthop_add_srv6_seg6local()` function uses `XCALLOC()` to allocate
memory for the SRv6 nexthop. This memory is never freed.
Creating a temporary `struct nexthop` is unnecessary, as the local SID
information can be pushed directly to the `struct zapi_route`. This
patch simplifies the implementation of `zclient_send_localsid()` by
avoiding using the temporary `struct nexthop`. This eliminates the need
to use `nexthop_add_srv6_seg6local()` to fill the `struct nexthop` and
consequently fixes the memory leak.

Handle matching type2/5 evpn routes via lookup in the optimized

Implement the ability to match type-2 and type-5 routes
via a route-map and a prefix-list.
Add some library code to convert an evpn prefix into
a general ipv4/ipv6 prefix for type-2 and type-5 routes.
evpn prefix is really just another subtype of prefix so all
the info needed can be extracted right there.
Add a special handler to bgp_routemap for evpn type routes
when applying the outbound route-map. This calls the library
code to convert the evpn_prefix to a ipv4/ipv6 prefix and
run it through the plist code. In this we assume type-2 routes
are a /32.

Add route-map as a possible word for the `no` form
of `advertise ipvX *** [route-map WORD] cmd.
Before this patch the cmd was only accepted if `no` form
was given without route-map WORD. So if you just copypaste
the original version of the cmd, it would fail.

Implement forcing L3 auto derivation via configs even when
manually RTs are set. This will allow both to coexist in
BGP RTs. Without using auto config command, it will remove
auto derived RTs when you manually configure your own. To allow
both, use the auto command ond import/export/both.
Implement '*' wildcard import L3 RTs so we can import a route into any AS.
This is necessary to avoid a user from having to configure an L3 RT for
every AS they care to import evpn route from.

Abstract the ecommunity into a container struct for L3
route targets so that we can add some additional info
via flags to go along with RT configs without modifying
the used elsewhere ecommunity struct. This functions as a
wrapper everywhere its used including the import/export lists.
The flags will be used in later commits to change behavior
when importing/exporting routes.

IPv4 and IPv6 behaves a little bit differently with the socket
options.
IPPROTO_RAW socket option is only for IPv4.
Therefore the register packet was not properly getting encapculated
for PIMv6 and was working fine for PIMv4.
So have used IPPROTO_PIM for PIMv6.

BGP SoO is a tag that is appended on BGP updates to allow a peer to mark
a particular peer as belonging to a particular site. In certain MPLS L3 VPN
configurations, the BGP AS-Path may not provide the granularity needed
prevent a loop in the control-plane. With this in mind, BGP SoO is designed
to fill this gap and prevent a routing loop that may occur.
If we configure for example, `neighbor soo 65000:1` at PEs, routes won't be
announced between CPEs if soo matches. This is especially needed when using
as-override or allowas-in.
Also, this is the automated way of the same behavior as configuring route-maps
for each peer like:
```
bgp extcommunity-list cpe permit soo 65000:1
!
route-map cpe permit 10
set extcommunity soo 65000:1
...
route-map cpe deny 10
match extcommunity cpe
route-map cpe permit 20
...
```

Fix issue #11839.
When the user defines a range in an area other than the backbone area, the
summary route will be announced to the backbone area as an inter-area LSA.
However, if the prefix defined in the range is the same prefix as a connected
route in that area, the LSA won't be announced to the backbone area.
This is because when ospf6d is originating the summary route for the
intra-area route, it finds the range configured by the user and tries to
suppress the route by deleting the existing summary route, which happens to be
the one created by the range.
Although the range definition is not necessary in this case, it should not
fail this use case. So let's just keep the summary route there if it is
created from the user defined range.
