Brian Feldman 42ebfbf227 Modify ktrace's general I/O tracing, ktrgenio(), to use a struct uio * 
instead of a struct iovec * array and int len.  Get rid of stupidly trying
to allocate all of the memory and copyin()ing the entire iovec[], and
instead just do the proper VOP_WRITE() in ktrwrite() using a copy of
the struct uio that the syscall originally used.

This solves the DoS which could easily be performed; to work around the
DoS, one could also remove "options KTRACE" from the kernel.  This is
a very strong MFC candidate for 4.1.
