53d93ef918 add a bridge object, modify bus object to be able to connect to other buses or bridges without panicing
SConscript:
    add new cc files to scons
mem/bus.cc:
mem/bus.hh:
    implement addressRanges() on the bus.
    propigate address ranges to anyone who is interested stripping out ranges of who your propigating to (to avoid livelock)
mem/packet.hh:
    add intersect function that returns true if two packets touch at least one byte of the same data (for functional access)
    add fixPacket() that will eventually take the correct action giving a timing and functional packet, right now it panics
mem/physical.cc:
    Don't panic if the physical memory recieves a status change, just ignore.

8e9d44477c Major update to sinic to support VSINIC better
dev/sinic.cc:
    - Size the virtualRegs array based on the configured value
    - Add debugging stuff for uniquely identifying vnic usage
    - Only count totally unprocessed packets when notifying via RxDone
    - Add initial virtual address support
    - Fix some bugs in accessing packets out of order to make sure that
    busy packets are processed first

    Create a separate list of Busy VNICs since more than one might
    be busy and we want to service those first
    Add more watermark stuff and new parameters
dev/sinicreg.hh:
    Make the number of virtual nics a read-only parameter
    add bits for ZeroCopy/DelayCopy
    rename Virtual to Vaddr so it's not ambiguous

    Added code to disassemble a trap instruction. This probably needs to be fixed up so there are immediate and register versions.
arch/sparc/isa/operands.isa:
    Added an R1 operand, and fixed up the numbering
arch/sparc/isa_traits.hh:
    SyscallNumReg is no longer needed, the max number of sources and destinations are fixed up, and the syscall return uses xcc instead of icc.
arch/sparc/linux/process.cc:
arch/sparc/linux/process.hh:
    Added a getresuidFunc syscall implementation. This isn't actually used, but I thought it was and will leave it in.
arch/sparc/process.cc:
arch/sparc/process.hh:
    Fixed up how the initial stack frame is set up.
arch/sparc/regfile.hh:
    Changed the number of windows from 6 to 32 so we don't have to worry about spill and fill traps for now, and commented out the register file setting itself up.
cpu/cpu_exec_context.hh:
cpu/exec_context.hh:
cpu/simple/cpu.hh:
sim/process.cc:
sim/process.hh:
    Changed the syscall mechanism to pass down the syscall number directly.
