a single-precision quiet NaN; only to be defined on platforms that do support
this value.

This means the stack frame and program counter can restored directly

which does not work in all cases.

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.

Quick fix to repair runtime link problem with libc - "SYS_sigaltstack
...
undefined". The sigaltstack structure layout didn't actually change on
the sparc, so just change the syscall name. A better fix would probably
be to replace the direct system call with a function call to the libc
sigaltstack().
