8d38dd3231 remove the extern C around gdb helper functions. It's need needed for any new version of gdb to work and it causes at least mine to segfault

1aef5c06a3 Rework the way SCons recurses into subdirectories, making it
automatic.  The point is that now a subdirectory can be added
to the build process just by creating a SConscript file in it.
The process has two passes.  On the first pass, all subdirs
of the root of the tree are searched for SConsopts files.
These files contain any command line options that ought to be
added for a particular subdirectory.  On the second pass,
all subdirs of the src directory are searched for SConscript
files.  These files describe how to build any given subdirectory.
I have added a Source() function.  Any file (relative to the
directory in which the SConscript resides) passed to that
function is added to the build.  Clean up everything to take
advantage of Source().
function is added to the list of files to be built.

03ff1c3167 Split the syscall table, SPARC specific syscall implementations, and the 32 bit syscall table into it's own file. Corrected problems with the stat structure. These should be tested on 64 bit x86 and SPARC machines.

ad44834907 Two fixes:
1. Make sure connectMemPorts() only gets called when the CPU's peer gets changed.  This is done by making setPeer() virtual, and overriding it in the CPU's ports.  When it gets called on a CPU's port (dcache specifically), it calls the normal setPeer() function, and also connectMemPorts().
2. Consolidate redundant code that handles switching in a CPU.

src/cpu/base.cc:
    Move common code of switching over peers to base CPU.
src/cpu/base.hh:
    Move common code of switching over peers to BaseCPU.
src/cpu/o3/cpu.cc:
    Add in function that updates thread context's ports.
    Also use updated function to takeOverFrom() in BaseCPU.  This gets rid of some repeated code.
src/cpu/o3/cpu.hh:
    Include function to update thread context's memory ports.
src/cpu/o3/lsq.hh:
    Add function to dcache port that will update the memory ports upon getting a new peer.
    Also include a function that will tell the CPU to update those memory ports.
src/cpu/o3/lsq_impl.hh:
    Add function that will update the memory ports upon getting a new peer.
src/cpu/simple/atomic.cc:
src/cpu/simple/timing.cc:
    Add function that will update thread context's memory ports upon getting a new peer.
    Also use the new BaseCPU's take over from function.
src/cpu/simple/atomic.hh:
    Add in function (and dcache port) that will allow the dcache to update memory ports when it gets assigned a new peer.
src/cpu/simple/timing.hh:
    Add function that will update thread context's memory ports upon getting a new peer.
src/mem/port.hh:
    Make setPeer virtual so that other classes can override it.

027dfa01e6 stop m5 from leaking like a sieve
don't create a new physPort/virtPort every time activateContext() is called
add the ability to tell a memory object to delete it's reference to a port and a method to have a port call deletePortRefs()
on the port owner as well as delete it's peer
still need to stop calling connectMemoPorts() every time activateContext() is called or we'll overflow the bus id and panic

src/cpu/thread_state.cc:
    if we hav ea (phys|virt)Port don't create a new on, have it delete it's peer and then reuse it
src/mem/bus.cc:
src/mem/bus.hh:

    add a function to do deleting
src/mem/cache/cache.hh:
