implement ipi stufff for SPARC

src/arch/alpha/utility.hh:
src/arch/mips/utility.hh:
src/arch/sparc/utility.hh:
src/arch/x86/utility.hh:
    add hook for system to startup the cpu or not... in the case of FS sparc, only the first cpu would get spunup.. the rest sit in an idle state until they get an ipi
src/arch/sparc/isa/decoder.isa:
    handle writable bits of strandstatus register in miscregfile
src/arch/sparc/miscregfile.hh:
    some constants for the strand status register
src/arch/sparc/ua2005.cc:
    properly implement the strand status register
src/dev/sparc/iob.cc:
    implement ipi generation properly
src/sim/system.cc:
    call into the ISA to start the CPU (or not)
