Patch from Eric Valette <valette@crf.canon.fr> and Emmanuel Raguet

<raguet@crf.canon.fr>:

    - the dec21140 driver code has been hardened (various bug fixed) Emmanuel,
    - bug in the mcp750 init code have been fixed (interrupt stack/initial
      stack initialization), BSS correctly cleared (Eric V)
    - remote debugging over TCP/IP is nearly complete (berakpoints,
      backtrace, variables,...) (Eric V),
    - exception handling code has also been improved in order to fully
      support RDBG requirements (Eric V),
