MessagePort: implement the virtual recvTiming function to avoid double pkt delete
...
Double packet delete problem is due to an interrupt device deleting a packet that the SimpleTimingPort also deletes. Since MessagePort descends from SimpleTimingPort, simply reimplement the failing code from SimpleTimingPort: recvTiming.

Replace curTick global variable with accessor functions.
...
This step makes it easy to replace the accessor functions
(which still access a global variable) with ones that access
per-thread curTick values.

X86: Create a directory for files that define register indexes.
...
This is to help tidy up arch/x86. These files should not be used external to
the ISA.

X86: Make the local APICs register themselves with the IO APIC.
...
This is a hack so that the IO APIC can figure out information about the local
APICs. The local APICs still have no way to find out about each other.
Ideally, when the local APICs update state that's relevant to somebody else,
they'd send an update to everyone. Without being able to do a broadcast, that
would still require knowing who else there is to notify. Other broadcasts are
implemented using assumptions that may not always be true.

X86: Record the initial APIC ID which identifies an APIC in M5.
...
The ID as exposed to software can be changed. Tracking those changes in M5
would be cumbersome, especially since there's no guarantee the IDs will remain
unique.
