Subject: * Code cleanup:   - remove trailing white space, trailing empty
 lines, C++ comments, etc.   - split cmd_boot.c (separate cmd_bdinfo.c and
 cmd_load.c)

* Patches by Kenneth Johansson, 25 Jun 2003:
  - major rework of command structure
    (work done mostly by Michal Cendrowski and Joakim Kristiansen)
