Large patch from Erik Ivanenko <erik.ivanenko@utoronto.ca> which

moves pieces of the pc386 bsp up to a shared level for all i386 BSPs
and modifies the i386ex BSP to use those shared pieces.  Serial remote
debugging is included for both targets.  Erik's notes:

    There are several workarounds in it:

     1) #define NEXT_GAS is hardcoded in pc386/start/start.s
     2)  #define NEXT_GAS is hardcoded in i386ex/start/start.s
     3) #define NEW_GAS is hardcoded in pc386/start16.s
     4) #undef __assert and redeclare _assert hardcoded in console.c for
        both pc386 and i386ex due to my egcs1.1b ~ newlib problem. Should have
        modified t-rtems.cfg ( no time )

    I've tested pc386 with both video and serial consoles and GDB remote.
    All work fine, except that GDB acts weird. ( re: other posting)

    I hope this will work for you.  It took quite some time to locate the
    autoconf error.  The remainder was just grunt work.
    Unfortunately, I think I've unwound the removal of the IBMPCInitVideo
    stuff. Sorry. I REALLY can't spend more time... I've been at this
    conversion to 4.0 locally and updating the release since Sept. 8th, and
    have yet to compile my network driver.... This is as much as I can do
    right now.

    I look forward to the next patch to really test i368ex.  I did make sure
    that the sample tests worked for pc386.
