* 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)

    where the binary vector (a(0),a(1),a(2),...,a(m-1)) is the representation
    of the integer "alpha_to[i]" with a(0) being the LSB and a(m-1) the MSB. Thus for
    example the polynomial representation of @^5 would be given by the binary
    representation of the integer "alpha_to[5]".

    "index_of[i]". Now, @^index_of[i] is that element whose polynomial
