frr: Update to version 9.1

frr: Update to version 9.1

- Update from version 8.5.2 to 9.1
- Update of rootfile
- Build dependencies of frr now include protobuf-c. protobuf-c requires protobuf.
   protobuf requires abseil-cpp.
- Build dependency of libyang will have a minimum version requirement of 2.1.128 coming
   out of an issue. Minimum version for frr-9.1 is 2.1.80 but excluding 2.1.111 due to
   API issues. Based on the near future requirement being 2.1.128 will move to current
   latest version of 2.1.148
- This patch set includes the above build dependencies
- Changelog
    9.1
	FRR 9.1 brings a long list of enhancements and fixes with 941 commits from 73
	 developers.
	OSPFv2 HMAC-SHA Cryptographic Authentication
		Specify that HMAC cryptographic authentication must be used on a
		 specific interface using a key chain.
	BGP MAC-VRF Site-Of-Origin support
		In some EVPN deployments, it is useful to associate a logical VTEP’s
		 Layer 2 domain (MAC-VRF) with a Site-of-Origin “site” identifier. This
		 provides a BGP topology-independent means of marking and
		 import-filtering EVPN routes originating from a particular L2 domain.
		 One situation where this is valuable is when deploying EVPN using
		 anycast VTEPs, i.e. Active/Active MLAG, as it can be used to avoid
		 ownership conflicts between the two control planes (EVPN vs MLAG).
	BGP Dynamic capability support
		Added support for Graceful-Restart, Long-lived Graceful-Restart,
		 Software-version, and Role BGP capabilities to be adjusted dynamically
		 using BGP dynamic capability.
		Dynamic BGP capability allows the dynamic update of capabilities over an
		 established BGP session. This capability would facilitate
		 non-disruptive capability changes by BGP speakers.
	IS-IS SRv6 uSID support (RFC 9352)
		The Segment Routing (SR) architecture allows a flexible definition of
		 the end-to-end path by encoding it as a sequence of topological
		 elements called "segments". It can be implemented over the MPLS or the
		 IPv6 data plane. This feature enables extensions in IS-IS to support
		 Segment Routing over the IPv6 data plane (SRv6) as per RFC 9352.
	Next-hop resolution via the default route
		Changed the default for a traditional profile to be enabled. The
		 datacenter profile is left as disabled.
	Add support for VLAN, ECN, DSCP mangling/filtering
		PBR maps are a way to specify a set of rules that are applied to packets
		 received on individual interfaces. If a received packet matches a rule,
		 the rule’s next-hop-group or next-hop is used to forward it; any other
		 actions specified in the rule are also applied to the packet.
		With this change, we added more commands for PBR maps, like matching
		 src-ip, dst-ip, src-port, dst-port, vlan, dscp, ecn, and more.
	libyang 2.1.80 related breaking changes
		prefix-list matching in route-maps is fundamentally broken with
		 libyang 2.1.111. If you have this version, please downgrade to the most
		 stable version 2.1.80.
		More details CESNET/libyang#2090
	Other significant changes
	    Zebra support for route replace semantics in FPM link
	    New command for BGP neighbor x addpath-tx-best-selected link
	    New command for BGP mpls bgp l3vpn-multi-domain-switching link
	    A couple more new BGP route-map commands:
	        set as-path exclude all link
	        set as-path exclude as-path-access-list link
	        set extended-comm-list delete link
	        set as-path replace <any|ASN> [<ASN>] link
	        set as-path replace as-path-access-list WORD [<ASN>] link
	        match community-list X any UPDATE
	Deprecations
	    Deprecate pre-standard outbound route filtering capability
	    Deprecate pre-standard route refresh capability
	    Drop deprecated capability
