Fixes for splash, may conflict with Korey's SMT work and doesn't support 03cpu yet.

src/cpu/simple/base.cc:
    Cpu's should start as unallocated, not suspended
src/cpu/simple_thread.cc:
    Wait for a thread to be assigned to activate the cpu
src/kern/tru64/tru64.hh:
    When looking for a open cpu to assign threads, look for an unallocated one, not a suspended one.
