What's worse, the tzfile.h that gets installed is over 20 years old
and doesn't match the real tzfile.h in libc/time. This makes the
tree safe for /usr/include/tzfile.h removal. The TM_YEAR_BASE
define has been moved to time.h temporarily until its usage is
replaced by 1900 in the tree. Actual removal of tzfile.h is pending
a ports build. Based on a diff from deraadt@
for a couple decades. Keep the OSIOCGIFCONF ioctl to support COMPAT_LINUX
but move the rest of the Linux-specific ioctl() handling into linux_socket.c

This hides the unavoidably cruddy sys/param.h namespace in some programs.
Little impact, because many programs are cruddy and still get it via

to returning strong random by default, source from arc4random(3).
Parameters to the seeding functions are ignored, and the subsystems remain
in strong random mode. If you wish the standardized deterministic mode,
call srand_deterministic(), srandom_determistic(), srand48_deterministic(),
seed48_deterministic() or lcong48_deterministic() instead.
The re-entrant functions rand_r(), erand48(), nrand48(), jrand48() are
unaffected by this change and remain in deterministic mode (for now).
Verified as a good roadmap forward by auditing 8800 pieces of software.
Roughly 60 pieces of software will need adaptation to request the
deterministic mode.

This is a getaddrinfo() flag that is defined thusly in RFC 3493:
If the AI_ADDRCONFIG flag is specified, IPv4 addresses shall be
returned only if an IPv4 address is configured on the local system,
and IPv6 addresses shall be returned only if an IPv6 address is
configured on the local system. The loopback address is not
considered for this case as valid as a configured address.
For example, when using the DNS, a query for AAAA records should
occur only if the node has at least one IPv6 address configured
(other than IPv6 loopback) and a query for A records should occur
only if the node has at least one IPv4 address configured (other
than the IPv4 loopback).
The flag is set by default when hints is NULL.
