4e2c4c42b4 Implement _atomic_cas_up() in assembly code as the compiler cannot be 
trusted to generate fully restartable code sequences.

Addresses lib/38482 for ARM and m68000.

73e50f111b Do like the non-__OPTIMIZE_SIZE__ variant, and compile memset() unless 
BZERO is defined, instead of requiring MEMSET to be defined.

Avoids violating the principle of least astonishment, and also fixes
the build of stand/ and kernels for (at least) alpha.

bb9b5eb92c In libc, use the MI atomic_cas(). The assembly version is faster, but I 
think there are PIC issues with it and I don't have a way to fix and test.

e6d6e05cb1 Including assym.h is not needed and will break the build, because it does not 
exist that early. Deleted it.

8346a6360d Use mkstemp() + fchmod() instead of mktemp(), since the latter

2ba84f0f9e Add tuned powerpc assembler written by IBM and released under a 3-clause 
BSD Lisc as part of the perflib project.
http://sourceforge.net/projects/ppcperflib/

Tested the new functions with microbenchmarks on a number of different
CPU types, and  found that most cpus either benefited greatly, or were
unaffected.  Primarily G4 CPU's were unaffected, and all others showed
speedups.  My 7044 (POWER3) went from a 70.6 to a 73.2 (thats good) in
bytebench with a complete release built with these.  Also passed
regression tests.

267197ec1e For all files under src/common, as well as related man pages under 
src/lib/libc, or related headers under src/sys/sys: change u_intNN_t to
uintNN_t.

cf01a0f8c8 C99 is no longer "very recent". Adjust a comment accordingly, and 
start using uintNN_t instead of u_intNN_t in the definitions of
sha2_{byte,word32,word64}.

ececdb7913 When passing char (or unsigned char) arguments as int, assign them to a 
temporary char (resp. unsigned char) before comparing, to force truncation
to the proper domain. This makes the coresponding regression tests succeed.
