Subject: [PATCH] More progress on checkpointing... we can now write out a
 checkpoint and read it back in, though most objects don't actually serialize
 any data.

dev/alpha_console.hh:
dev/console.cc:
dev/console.hh:
    Change unserialize param from IniFile& to const IniFile*.
cpu/simple_cpu/simple_cpu.cc:
    Change unserialize param from IniFile& to const IniFile*.
    Make unserialize call ExecContext::unserialize.
sim/eventq.cc:
    Rename MainEventQueue (no spaces) for easier parsing in checkpoints.
    Disable event serialization for now, so we can focus on the easy stuff.
sim/serialize.cc:
    Change paramIn and arrayParamIn param from IniFile& to const IniFile*.
sim/serialize.hh:
    Change unserialize, paramIn, and arrayParamIn params from IniFile& to const IniFile*.
