cd114adca5 This commit includes two major changes: 
1) Speed up arc4random().  We make arc4randbyte() inline, which makes this
   not much slower than, say, the other arc4 implementation in our kernel.

   We also replace four calls to arc4randbyte() with a loop, saving about
   20% on some processors where the "unrolled" arc4randbyte() calls would
   needlessly stomp the cache.

2) Address various problems with the initialization/"stirring" code,
   primarily in the area of handling of the source data from the kernel
   entropy pool.  We used to:

	a) Ask the entropy pool for 32 bytes

	b) If we got zero bytes, key with junk from the stack (ouch!)
	   which has some nasty implications, to say the least.  For
	   example, we're most likely to get zero bytes at boot time,
	   when the stack contents are even more predictable than usual.

	c) If we got less than 32 bytes but more than zero bytes, use
	   however many bytes we got as the arc4 key, copying it
	   repeatedly as per usual arc4 key setup.

	   Because of the way NetBSD's entropy pool works, this was
	   mostly harmless, because if you ask for RND_EXTRACT_ANY,
	   you always get as many bytes as you ask for.  However,
	   this is probably a security hole in the original FreeBSD
	   code, where AFAICT you might end up using an 8-bit arc4
	   key -- not good, much worse than using the output of the
	   entropy pool hash function even when it thinks it only
	   has 8 bits of entropy to give you.

	   One thing this code could do on NetBSD that was not so
	   good was to replace a key with a lot of entropy with
	   one with less entropy.  That's clearly counterproductive.

   The new code, instead:

	a) Asks for 32 good bytes.  If it gets them, use them as the
	   arc4 key in the usual way.

	b) Tracks how many entropy bytes the key it's replacing had.
	   If the new entropy request got less bytes, leave the old
	   key in place.  Note that the first time through, the "old
	   key" had zero bytes, so we'll always replace it.

	c) If we get less then 32 bytes but more than we had, request
	   EXTRACT_ANY bytes from the entropy pool, padding the key
	   out to 32 bytes which we then use as the arc4 key in the
	   usual way.

This is still really all rather backwards.  Instead of this generator
deciding to rekey itself using a basically arbitrary metric, it should
register a callback so that the entropy pool code could rekey it when
a lot of bits were available.  Details at 11.

Finally, rename the "stir" function (which did not stir) to "rekey",
which is what it actually does.

f89823c1f8 Save 1-4 instructions on all cases except for the ret=0 case. 
This is probably the last version from me. :)
You are welcome to speed it up, of course. :)

Here's a benchmark on SH-4 200MHz.
9.2% faster if all the cases occur evenly.

70b5675025 Assembly version of ffs(3). 
Confirmed to return the same value as that of the C version.

The results of a simple benchmark on SH-4 200MHz, is shown below.

59474a8c82 NetBSD, meet the SH-5 cpu. 
SH-5, meet NetBSD.

Let's hope this is the start of a long and fruitful relationship. :-)

This code, funded by Wasabi Systems, adds initial support for the
Hitachi SuperH(tm) SH-5 cpu architecture to NetBSD.

At the present time, NetBSD/evbsh5 only runs on a SH-5 core simulator
which has no simulated devices other than a simple console. However, it
is good enough to get to the "root device: " prompt.

Device driver support for Real SH-5 Hardware is in place, particularly for
supporting the up-coming Cayman evaluation board, and should be quite
easy to get running when the hardware is available.

There is no in-tree toolchain for this port at this time. Gcc-current has
rudimentary SH-5 support but it is known to be buggy. A working toolchain
was obtained from SuperH to facilitate this port. Gcc-current will be
fixed in due course.

The SH-5 architecture is fully 64-bit capable, although NetBSD/evbsh5 has
currently only been tested in 32-bit mode. It is bi-endian, via a boot-
time option and it also has an "SHcompact" mode in which it will execute
SH-[34] user-land instructions.

For more information on the SH-5, see www.superh.com. Suffice to say it
is *not* just another respin of the SH-[34].

uses the PC devices that it simulates for now. It will be developed

2dc247fc34 make CMSG_ALIGN always synchronize with kernel's idea of ALIGNBYTES. 
ancillary data alignment will be ALIGNBYTES, not sizeof(long) - 1, from now.

CMSG_xx will NOT resolve into constant.  if you use CMSG_xx to allocate
arrays, you'll lose.

bump shlib minor for libc.

NOTE: if you are on top of arch with ALIGNBYTES != sizeof(long) - 1,
you need to recompile IPv6-related binaries.  there is no way to guarantee
backward compat in this aspect.  sorry for this.  this should be the last
backward compat breakage for IPv6-related ancillary data manipulation.
