dc306354b0 Move the bswap functions from libutil to libc (this bups the 
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

eae488f7bb Fix typo, which resulted in always compiling the M68040/M68060-version

31c3c1a2b3 Most calls of ldexp() won't be with a first parameter of 0.0. Don't penalize 
them for a slight optimization of the zero case.

is
e6cb27b508 ieee.h and ldexp.c taken from the powerpc port, for the benefit of 
68040 and 68060 owners.
With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp()
doesn't use excessive amounts of system cpu time.
Without any of those defines, the normal assembler version using FSCALE is
included, for the benefit of M68020 and M68030 users, or M68040/M68060 users
where the ldexp performance is no bottleneck.
[Its not yet worked out how to include both library versions in a binary
distribution, but you can build your own from source now if you need it.]
For details, look at PR 3105.

ac11de32c1 Actually, bitfields are faster on the '040; optimize for it, but adjust the 
fields so that the mask and sticky bits are the same.

03dbf74333 inline call to sigreturn original idea from jason downs <downsj@CSOS.ORST.EDU> 
we want this to be done for everything including non-PIC code as longjmp()
does non-standard things with regs and wouldn't like it if the user replaced
the sigreturn() stub.
