    Include XSTATE note in x86 core dumps

    Introduce a simple COREDUMP_MACHDEP_LWP_NOTES logic to provide machdep
    API for injecting per-LWP notes into coredumps, and use it to append
    PT_GETXSTATE note.

    Since the XSTATE block uses the same format on i386 and amd64, the code
    does not have to conditionalize between 32-bit and 64-bit ELF format
    on that.  However, it does need to distinguish between 32-bit and 64-bit
    PT_* values.  In order to do that, it reuses PT32_* constant already
    present for ptrace(), and adds a matching PT64_GETXSTATE to satisfy
    the cpp logic.
