  Modified files:
    sys/conf             files 
    sys/ddb              db_command.c db_input.c db_main.c 
                         db_output.c ddb.h 
  Added files:
    sys/ddb              db_capture.c 
  Log:
  Add a new DDB(4) facility, output capture.  Input and output from DDB may be
  captured to a memory buffer for later inspection using sysctl(8), or in the
  future, to a textdump.
  
  A new DDB command, "capture", is added, which accepts arguments "on", "off",
  "reset", and "status".
  
  A new DDB sysctl tree, debug.ddb.capture, is added, which can be used to
  resize the capture buffer and extract buffer contents.
