  Log:
  Merge kern_ktrace.c:1.102, ktrace.h:1.30 from HEAD to RELENG_6:
  
    Replace ktr_buffer pointer in struct ktr_header with a ktr_unused
    intptr_t.  The buffer length needs to be written to disk as part
    of the trace log, but the kernel pointer for the buffer does not.
    Add a new ktr_buffer pointer to the kernel-only ktrace request
    structure to hold that pointer.  This frees up an integer in the
    ktrace record format that can be used to hold the threadid,
    although older ktrace files will have a garbage ktr_buffer field
    (or more accurately, a kernel pointer value).
