lib: create `frr_daemon_state_{load,save}`
These functions load daemon-specific persistent state from
`/var/lib/frr` and supersede open-coded variants of similar calls in
ospfd, ospf6d and isisd to save GR state and/or sequence numbers.
Unlike the open-coded variants, the save call correctly `fsync()`s the
saved data to ensure disk contents are consistent.

build: untangle sysconfdir & localstatedir
`--sysconfdir` should be `/etc` and `--localstatedir` should be `/var`.
The package-specific subdirectory should be added by configure, not
given by the user, to match established behavior by other packages.
Note that `--bindir`, `--sbindir`, `--libdir` and `--libexecdir` have
different established/expected behavior due to distro specific
multi-arch support. That's why these are left unchanged.
The reason this is getting fixed now is that we need to use
`--localstatedir` for its actual value to put things in `/var/lib`. As
it is now, being overloaded for `/run`, the configured `/var` path
becomes inaccessible.

Issue:
Previously, the PBR common was updated for every rule update or deletion
example:
let say we have three rule 11, 12, 13 and if we are removing rule 12. in the current code
we are making the entire map "valid" to false.
pbr-map MAP1 seq 11
match src-ip 90.1.1.2/32
set nexthop 20.1.1.2 swp1
pbr-map MAP1 seq 12
match src-ip 90.1.1.3/32
set nexthop 20.1.1.2 swp1
pbr-map MAP1 seq 13
match src-ip 90.1.1.4/32
set nexthop 20.1.1.2 swp1
no pbr-map MAP1 seq 12 ==> turns whole map valid to false.
r1(config)# end
r1# show pbr map
pbr-map MAP1 valid: no
Seq: 11 rule: 310
Installed: yes Reason: Valid
SRC IP Match: 90.1.1.2/32
nexthop 20.1.1.2 swp1
Installed: yes Tableid: 10002
Seq: 13 rule: 312
Installed: yes Reason: Valid
SRC IP Match: 90.1.1.4/32
nexthop 20.1.1.2 swp1
Installed: yes Tableid: 10004
Fix:
Now, the PBR common will only be updated when the last rule is being deleted.
This change ensures that we only send a delete request to Zebra once, and only
set the valid and installed flags to false when the last rule is deleted.
This optimizes the handling of PBR rules and reduces unnecessary interactions with Zebra

lib: remove leaf-list xpath hack from northbound
Currently, when editing a leaf-list, `nb_candidate_edit` expects to
receive it's xpath without a predicate and the value in a separate
argument, and then creates the full xpath. This hack is complicated,
because it depends on the operation and on the caller being a backend or
not. Instead, let's require to always include the predicate in a
leaf-list xpath. Update all the usages in the code accordingly.
