Modified Files:
        src/sys/arch/mips/include: signal.h

Log Message:
Adjust the rules for sigcontext visibility on MIPS:
- Define __HAVE_STRUCT_SIGCONTEXT if _KERNEL (because it's needed for
  32-bit binary compatibility) or if the O32 ABI is active (because
  that's the only ABI that ever used sigcontext for signal delivery).
- For _KERNEL, define a "struct sigcontext" suitable only for 32-bit
  compatible signal delivery.
- For userspace, define a "struct sigcontext" appropriate for any ABI
  if _LIBC is defined (it's used for setjmp / longjmp) or if O32 is
  the active ABI (because it was part of the old BSD signal API).
