7fbae5b706 tree-wide: use C99 __func__ rather than obsolete __FUNCTION__ 
We use __func__ almost everywhere, but there are some holdouts. Fix
that.

fe92eb795b network: use official bswap_32() rather than inofficial __bswap_32() 
The former is a macro for the latter, but let's use the official API
(the one that has an API).

e210f027e0 sd-dhcp6-client: rename dhcp6_lease_set_dns() -> dhcp6_lease_add_dns()

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.

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.
