* fixed compile issues with prior release
* fixed carrier loss not being detected for IPv4
* UUID based DUID is used where available and no prior DUID exists
Replace unportable manual calculation of alignof() that causes UB, with
a GCC extension __alignof__.
This fixes a problem reported by UBSan with the MKSANITIZER distribution.
that are not very useful (and trully if any they belong to a separate section
instead of being interspersed in the document), and organizes and formats
the information better.
Sanitizers are conflicting with this option:
When linking shared libraries, the AddressSanitizer run-time is not
linked, so -Wl,-z,defs may cause link errors (t use it with
AddressSanitizer).

When linking shared libraries, the MemorySanitizer run-time is not
linked, so -Wl,-z,defs may cause link errors (t use it with
MemorySanitizer).

Root cause of breaking libc++ investigated by <Yang Zheng>
- Replace non-printable multibyte char with ?-symbol.
- Put space before non-spacing char.
Fix problems reported in PR bin/53164 and
PR bin/53323, that are because we did not take into account non-printable
multibyte char of wctob(wc) == EOF && wcwidth(wc) == -1.
This change breaks the expectations of users that would like a coredump
of top(1). Other similar applications such as vmstat(1) don't do this.
Since the change was just a courtesy, revert.
* dhcp: Clarified some checksumming code, style and commentary
(thanks to Maxime Villard)
* dhcp6: IAID is now unique per IA type rather than global
* ip6: if an IA callback causes a fork, exit earlier
The cp_old array is allocated with malloc(3) and its pointer is passed to
percentages64().
In this function there happens a calculation of total_change, which value
depends on the value inside the unitialized cp_old[] array.

Fix this issue by changling malloc(3) with calloc(3).
Detected with Memory Sanitizer during the integration of sanitizers with
the NetBSD basesystem.

programs there; make all Makefiles that use bsd.hostprog.mk include it.
Namely turn off MKREPRO and don't make lint, man pages, info files etc.
Remove the Makefile.inc files that contained these same settings, and
remove the settings from Makefile.host
tcp_timer.h. This struct move is more trouble than its worth. It breaks
header compatibility with other BSD's and can't be really removed because
it is an installed header that will break other 3rd party software. I
suggest that it gets reverted!
