incorrectly internally on certain divides.
Handle the case where the internal result appears negative. This condition
can occur when dividing MIN_INT by certain values.

Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern.
...
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

Add machine-independent assertion-checking support. macros are:
...
assert() which always does assertion checking
unless "NDEBUG" is defined.
KASSERT() which does assertion checking if DIAGNOSTIC
is defined.
KDASSERT() which does assertion checking if DEBUG is
define. This macro exists for compatibility
with existing ports' assertion checking macros.
(Assertion checking is not typically an
"expensive" operation, and DIAGNOSTIC should be
used for inexpensive consistency checks.)

add strncasecmp.c to ports' libkern Makefile.inc's. When adding a new
...
source file to libkern, it should be added to _ALL_ ports makefiles if
it is machine-independent and used by machine-independent code (in
this case adosfs). (There are several arguments that say that
strncasecmp should not be in libkern at all, and i think they're
good ones, but as long as ADOSFS needs it to link, it has to be here
for all architectures.)
