e210f027e0 sd-dhcp6-client: rename dhcp6_lease_set_dns() -> dhcp6_lease_add_dns() 
As it is allowed that multiple DNS server options appear in the message.

e693e96961 sd-dhcp6-client: do not merge NTP and SNTP options 
Previously, SNTP option is ignored when it appears after NTP option(s),
but merged later NTP options when it appears first.
This makes split the NTP and SNTP addresses, and use SNTP addresses only
when no NTP option is provided.

9c3d46bf8d sd-dhcp6-client: support multiple NTP server options

suboption contains one NTP server.

ad3c84204c sd-dhcp6-client: fix buffer size calculation in dhcp6_option_parse_ip6addrs() 
GREEDY_REALLOC() takes number of elements, not buffer size.

This also rename dhcp6_option_parse_ip6addrs() to
dhcp6_option_parse_addresses().

8a8955507a sd-dhcp6-client: modernize dhcp6_option_parse_ia() 
This makes
- the function not update the arguments for storing results on error,
- use dhcp6_option_parse() to parse sub options,
- ignore all errors, except for -ENOMEM, in parsing sub options,
- update log messages.

4af39cb8ec sd-dhcp6-client: make dhcp6_option_parse_status() also parse error message 
This also introduce dhcp6_option_parse_ia_options(). Currently, it is
assumed that each IA address or PD prefix may contain a status sub-option.
But it is not prohibited that other sub-options or multiple status
options are contained.

b89a3758e9 sd-dhcp6-client: modernize dhcp6_option_parse() 
- merge dhcp6_option_parse() with option_parse_hdr().
- do not assign/update any values on error.
- use assert() instead of assert_return(), as the assertions cannot
  be triggered by a library user.

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.

04499a70fb Drop the text argument from assert_not_reached() 
In general we almost never hit those asserts in production code, so users see
them very rarely, if ever. But either way, we just need something that users
can pass to the developers.

We have quite a few of those asserts, and some have fairly nice messages, but
many are like "WTF?" or "???" or "unexpected something". The error that is
printed includes the file location, and function name. In almost all functions
there's at most one assert, so the function name alone is enough to identify
the failure for a developer. So we don't get much extra from the message, and
we might just as well drop them.

Dropping them makes our code a tiny bit smaller, and most importantly, improves
development experience by making it easy to insert such an assert in the code
without thinking how to phrase the argument.
