01afd0f7f5 tree-wide: make format_ifname() or friends return negative errno on failure 
Also,
- drop unnecessary +1 from buffer size, as IF_NAMESIZE or IFNAMSIZ
  includes the nul at the end.
- format_ifname() does not update buffer on failure,
- introduces format_ifname_alloc(), FORMAT_IFNAME(), and their friends.

d7ac09520b tree-wide: mark set-but-not-used variables as unused to make LLVM happy 
LLVM 13 introduced `-Wunused-but-set-variable` diagnostic flag, which
trips over some intentionally set-but-not-used variables or variables
attached to cleanup handlers with side effects (`_cleanup_umask_`,
`_cleanup_(notify_on_cleanup)`, `_cleanup_(restore_sigsetp)`, etc.):

```
../src/basic/process-util.c:1257:46: error: variable 'saved_ssp' set but not used [-Werror,-Wunused-but-set-variable]
        _cleanup_(restore_sigsetp) sigset_t *saved_ssp = NULL;
                                                     ^
                                                     1 error generated.

89fa013349 network: use NetworkConfigSource/State to manage nexthops 
This also changes the logic when Id= is not specified.
Previously, kernel picks the lowest unused ID, but now networkd picks
the lowest unused ID.

eb72fa3ad2 network: use NetworkConfigSource/State to manage routing policy rules 
This also changes the logic when Priority= is not specified.
Previously, we request without FRA_PRIORITY attribute and kernel picks
the highest unused priority for the rule.
This makes networkd picks the highest unused priority and always request
FRA_PRIORITY attribute.

981fab5d0a network: always call address ready callback if address is ready 
The address ready callback is used for cleaning up old addresses or
routes acquired by e.g. DHCP. However, the callback was called only
when the address was previously not ready. So, maybe, unnecessary
addresses or routes may not be cleared.

Also, this makes the callback is called slightly earlier. As it may
remove several addresses or routes, and possibly changes the link state.

f1c22cf4da network: do not try to drop addresses or routes of unmanaged interfaces on carrier lost 
Currently, link_stop_engines(), link_drop_config(), and link_drop_foreign_config()
do nothing when the interface is unmanaged. So this does not change anything.
But returning earlier should be clear and safer for protecting configs
on unmanaged interfaces.
