New Revision: 335091
URL: https://svnweb.freebsd.org/changeset/base/335091

Log:
  Make it possible to use print_controller from another program
  
  Rename print_controller to nvme_print_controller. Put it in its
  own file for easy inclusion. Move util.c to be nc_util.c to not
  conflict with camcontrol. add nvecontrol_ext.h to define shared
  interfaces.
