Patch from Emmanuel Raguet <raguet@crf.canon.fr> to add remote debug server

and RPC support to RTEMS.  Thanks. :)  Email follows:

    Hello,

    For Xmas, here is the Remote Debugger on RTEMS !

    Here are 2 patches for the Remote Debugger on RTEMS for pc386 from Linux
    host :

     - one for RTEMS it self,
     - one for GDB-4.17.


    1/ RTEMS patch
    --------------

    This patch adds 2 libraries :
     - a simplified SUN RPC library
     - the Remote Debugger library

    The configuration command is the following :
    ../rtems4/configure --target=i386-rtemself --enable-rtemsbsp=pc386
    --enable-rdbg

    The SUN RPC library is built only if networking is set.
    The RDBG library is built if networking and enable-rdbg are set.

    The function used to initialize the debugger is :
            rtems_rdbg_initialize ();

    A special function has been created to force a task to be
    in a "debug" state : enterRdbg().
    The use of this function is not mandatory.



    2/ GDB-4.17 patch
    -----------------

    This patch create a new RTEMS target for GDB-4.17.

    The configuration command is the following :
    ./configure --enable-shared --target=i386RTEMS

    To connect to a target, use :
      target rtems [your_site_address]

    Then, attach the target using : attach 1

    And... Debug ;)

    You can obtain the original GDB-4.17 on
    ftp://ftp.debian.org/debian/dists/stable/main/source/devel/gdb_4.17.orig.tar.gz

    This has been tested from a Debian 2.0.1 linux host.
