As part of this effort, the mpc750 libcpu code is now shared with the
ppc6xx.

<raguet@crf.canon.fr> to fix bugs and make the mcp750 boot
RTEMS running the GoAhead web server.

<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),

- The same bug fix that was done on pc386 to prevent interrupt
from occuring (never experienced it but who knows as I have 8259
emulation :()
- Removed every compiler warning (except wrong ones and ones I can't do
anything).
- Removed any libc available code in code linked with mcp750 rtems
executbale. Unfortunately using newlib functions for linking the
bootloader does not work as the compilation options in bootloader
(-mrelocatable -fixed-r13) are not compatible with newlib options.
=> I have put any libc external reference in one single new file (lib.c)
that is linked only with the boot loader. Removing the file from
${OBJ} and using -lc crash the bootloader. Added big warning...

I have made test with the Dec21140 driver and it appears that all
works fine even if the cache is enabled for the memory space in
which the incoming and outcoming Ethernet frames are stored.
I have had #ifdef to "comment" the code. If you want to disable
cache, you only have to #define the name. It could be mandatory
for some BSPs.

that were accidentally not committed earlier. The DECNet driver
is being added as its own directory to avoid forcing the driver to
have to pull in the complete set of network drivers.
