Changed BaseCPU::ProfileEvent's interval member to be of type Tick. This was done to be consistent with its python type of a latency. In addition, the multiple definitions of profile in the different cpu models caused problems for intialization of the interval value. If a child class's profile value was defined, the parent BaseCPU::ProfileEvent interval field would be initialized with a garbage value. The fix was to remove the multiple redifitions of profile in the child CPU classes.

sockets: Add a function to disable all listening sockets. When invoking several copies of m5 on the same machine at the same time, there can be a race for TCP ports for the terminal connections or remote gdb.

There are some SimObjects that have no other function than to be used with ports (NativeTrace and EtherTap), so they will panic if the ports are disabled.

process: separate stderr from stdout - Add the option of redirecting stderr to a file. With the old behaviour, stderr would follow stdout if stdout was to a file, but stderr went to the host stderr if stdout went to the host stdout. The new default maintains stdout and stderr going to the host. Now the two can specify different files, but they will share a file descriptor if the name of the files is the same. - Add --output and --errout options to se.py to go with --input.

eventq: new eventq data structure. The new data structure is singly linked list sorted by time and priority. For things of the same time and priority, a second, circularly linked list maintains the data structure. Events of the same time and priority are now inserted in FIFO order instead of LIFO order.

Change everything to use the cached virtPort rather than created their own each time. This appears to work, but I don't want to commit it until it gets tested a lot more. I haven't deleted the functionality in this patch that will come later, but one question is how to enforce encourage objects that call getVirtPort() to not cache the virtual port since if the CPU changes out from under them it will be worse than useless. Perhaps a null function like delVirtPort() is still useful in that case.

After a checkpoint (and thus a stats reset), the not_idle_fraction/notIdleFraction statistic is really wrong. The notIdleFraction statistic isn't updated when the statistics reset, probably because the cpu Status information was pulled into the atomic and timing cpus. This changeset pulls Status back into the BaseSimpleCPU object. Anyone care to comment on the odd naming of the Status instance? It shouldn't just be status because that is confusing with Port::Status, but _status seems a bit strage too.

Get rid of bogus bus assertion. It runs out that if a MemObject turns around and does a send in its receive callback, and there are other sends already scheduled, then it could observe a state where it's not at the head of the list but the bus's sendEvent is not scheduled (because we're still in the middle of processing the prior sendEvent).

Get rid of bogus cache assertion. I was asserting that the only reason you would defer targets is if a write came in while you had an outstanding read miss, but there's another case where you could get a read access after you've snooped an invalidation and buffered it because it applies to a prior outstanding miss.
