Current denominators are not integers and some of them lose precision
because of that, for example, 1e-6 is actually stored as
9.9999999999999995e-07 and 1-e12 is stored as 9.9999999999999998e-13.
When multiplying by such denominators, we receive incorrect values.
Changing denominators to integers and using division instead of
multiplication improves precision and solves the problem.

It shouldn't be set unless some affinity is configured. NB callbacks

Make link-params a presence container and activate it when entering the

Introduce new "[no] multicast <enable|disable>" command to be able to
remove the configuration. Current "[no] multicast" command cannot be
removed. Current command is hidden but still works for backwards

We shouldn't pass "lo" as an interface to create_interface_in_kernel.
It always exists, and this function flushes all configured IP addresses
from it.

With a current pam_rootok.so, it works only with `root` account. If the user
is under `frrvty`, `frr` group, it gets the error:
```
% groups | grep -o -E "frrvty|frr"
frrvty
frr
% vtysh -c 'end'
vtysh_pam: Failed in account validation: Permission denied(6)
```
Checking the logs:
```
vtysh[23930]: pam_rootok(frr:account): root check failed
```

When no data requests were sent to the backends, return immediately,
instead of waiting for a timeout. This can happen if backends providing
the requested data are not connected to mgmtd.

Use consistent `e_somepath` names for expanded versions of `somepath`.
Also remove all paths from `config.h` and put them into
`lib/config_paths.h` - this is to make more obvious when someone is
doing something probably not quite properly structured.

Both of these belong in `/var/lib`, not `/var/run`.
Rather hilariously, the history read in
`mgmt_history_read_cmt_record_index` was always failing, because it was
doing a `file_exists(MGMTD_COMMIT_FILE_PATH)` check. Which is the wrong
macro - it's `.../commit-%s.json`, including the unprocessed `%s`, which
would never exist.
I guess noone ever tried if this actually works. Cool.
On the plus side, this means I don't have to implement legacy
compatibility for this, since it never worked to begin with.
(SQLite3 DB location is also changed in this commit since it also uses
`DAEMON_DB_DIR`.)

Unfortunately, `ospf6d` is much worse than `ospfd` and `isisd` regarding
its state saving, due to the existence of the auth trailer code.
Again, this belongs in `/var/lib`, not `/var/run`.
Merge both state files into one, and add reconciliation code for the
auth seqno.
I'm gonna save my comment on the fact that `ospf6_auth_seqno_nvm_delete`
is not in fact used anywhere. Which is now a warning because it's
`static`. Well. It probably should be used somewhere, so leave it in.

Use library facility to load/save, support previous path as fallback,

This belongs in `/var/lib`, not `/var/run`. Also the filename was
typo'd (`isid-restart.json`).
Change to proper location and fall back to previous in case it's the
first restart after an FRR update from a version with the bugged path.

clang-format doesn't understand FRR_DAEMON_INFO is a long macro where
laying out items semantically makes sense.
(Also use only one `FRR_DAEMON_INFO(` in isisd so editors don't get
confused with the mismatching `( ( )`.

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.

This needs to be used for persistent state, which currently is misplaced
into `/var/run` / `/run` where it gets deleted across reboots.

`--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.
