fix problems on darwin/*BSD for syscall emulation mode

arch/alpha/alpha_linux_process.cc:
arch/alpha/alpha_tru64_process.cc:
    fixup for bsd hosts. Some headers are included by default which means that
    more variables need TGT_ prefixes and there isn't a stat call (everything
    is a stat64 call) so we have to work around that a bit
base/intmath.hh:
base/socket.cc:
    this is no longer needed with mac os 10.4
cpu/inst_seq.hh:
    just use a uint64_t instead of long long
cpu/o3/inst_queue_impl.hh:
    I much cleaner way to get max int
sim/syscall_emul.hh:
    fix stat64 problems on *BSD
