d582bd909a In the misaligned case, xor the read word with the target pattern 
before making the unwanted bytes non-zero.
Means that memchr(buf, 0xff) is no longer a special case.

170e962b6c Remove some long dependant instruction sequences (ie allow parallel code). 
Since 'rep stos' will have a long setup time, avoid doing it more than once.
For misaligned (start address or length) write an unaligned word at both
ends of the buffer then aligned 'rep stosd' the middle.
Use the same code for bzero().
bzero.S is left being compiled for a while (empty) - to avoid issues with
duplicate symbols in libc.a after update builds.

0578c2ad0f Move popcount et al to src/common and add popcount32/popcount64. 
Requested by rmind@. MD should now override popcount32/popcount64 and
provide the aliases as fitting.

28a175e482 Put back dsl's string changes, but fix memchr.S to use cmp (rather 
than test) so that the condition code is set correctly (and fix the
comments: 0x10->0x01 and ^->&).   From Anon Ymous

XXX: There are similar comment errors in some of the other string code.

XXX: We really need a regression test that includes misaligned memory
with searches designed to catch corner cases such as searching for 0,
-1, etc, and search length limit violations.  Searching for 0 on
misaligned memory would have caught this problem.

97943df1a9 A better memchr(). 
Always read aligned words, invalidating unwanted bytes in first word,
and checking that any match in the last word is before the buffer end.
No loops apart from the one through the data.

6bdd82f5c7 Shorten a dependency chain by using 'sbb, xor' (at a time when carry is set) 
instead of 'mov, neg, dec'.
('mov, not' can't be used because it doesn't set the flags.)

6054206dee Replace with a version that: 
1) doesn't do byte compares to find which byte matched
2) doesn't do byte compares if any top bits are set
3) doesn't use a loop when the input is misaligned
4) has less mispredicted branches
Passes regression tests and 'build.sh' doesn't explode (and more than usual).

66df44074f After alg 2 triggers, mask with ~x (alg 3) to ignore bytes with top bit set. 
Then use bit scan to work out which byte is zero.
If the source is misaligned read the aligned word and make the unwanted
(low order) bytes non-zero.
Passes regression test - which probably tests just enough cases.

b1946a6b32 Back out the addition of memset.c to the vax libkern, and instead do 
as tsutsui@ suggested, and include <sys/param.h> in sha2.c instead.
On the vax, this causes <machine/macros.h> to be included, and it contains
that machine's memset() macro+inline.
