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

- 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),
