    <sys/uio.h>: Extract kernel structures to a separate header.
    
     The only userspace user of these bits is kdump(1) that already properly
     defines _KERNEL_STRUCTURES before including system headers.
     * Put ui_rw and ui_seg enums under _KERNEL_STRUCTURES.
     * Adjust <sys/ktrace.h> for 'struct ktr_genio' visibility too.
    
     Handling KTR_GENIO requires special knowledge (hidden members) and
     kdump(1) is also a single userspace case using it. This does not affect
     utilities like ktrace(1) and allows for further cleanups.
