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.
Violates POSIX and C89, which violate best practice in this century.

Some 64-bit platforms (e.g. Windows 64) have a 32-bit long. So, shifting
1UL 32-bits to the left causes an overflow. This replaces the constant 1UL with
(size_t)1 so that we get the correct constant size for the platform.

Several functions that need to be redefined for a Windows port are right
in the middle of other code that is relatively portable. This patch
isolates the functions that need Windows-specific implementations so
they can be built conditionally in the portable tree.

Treat rtsol in hostname.if as a keyword like dhcp and call ifconfig

OK krw@ (who is *not* an IPv6 person), but I recruited him in his
capacity as an installer person.

The former is not used anywhere in NetBSD, FreeBSD, or DragonFly
and not supported by groff, so i'm going to delete it from mandoc(1).
We don't need two macros for the same thing.

(potentially) MD versions (function dependent, not filename dependent)
split out memcpy/memmove/bcopy and strchr/index/strrchr/rindex
Bring back amd64 .S versions
And the final touch: switch all architectures temporarily to MI
memcpy.c, which contains syslog + abort for overlapping copies.  A nice
harsh undefined behaviour.  We will clean the entire userland of the
remaining issues in this catagory, then switch to the optimised memcpy
which skips the memmove check.
I tried to cut this change into pieces, but testing each sub-step on
every architecture is too time consuming and mindnumbing.

Remove the bug about rand() being faster.
Add a bug about historical implementations seeding very poorly.

better to find one instead of continuing to mangle this mess.

only doing what's needed for crypt_hashpass. sigh.

write out a hash. also simplify writing out the hash.

for quite some time.  Mop up the last few, by using /dev/random where we
actually want it, or not even mentioning arandom where it is irrelevant.
