  Modified files:
    sys/conf             files 
    sys/sys              libkern.h 
  Added files:
    sys/libkern          strvalid.c 
  Log:
  Add a 'strvalid()' call to libkern.  Given a character pointer, and
  buffer length, determine if the pointer is to a valid string.  Currently,
  the only check is whether a '\0' appears in the buffer.  This is useful
  when pulling in a structure from userland that may contain one or more
  strings, and validity testing must be performed on elements of the
  structure.  When copying normal string arguments, copyinstr() is
  expected to be used.
