arch, base, sim: Demote (SE|FS)TranslatingPortProxy &s to PortProxy &s.
Al(most) all of the interesting differences between the two classes have been removed. There are some control methods which are still specific to each type which may require treating them as their true type, but most code that consumes them doesn't need to worry about which is which.

mem: Remove the ISA specialized versions of port proxy's read/write.
These selected their behavior based on ifdefs and had to be disabled when on the NULL ISA. The versions which take an explicit endianness have been renamed to just read/write instead of readGtoH and writeHtoG since the direction of the translation is obvious from context.

sim: Add helper functions that add PCEvents with custom arguments
This changeset adds support for forwarding arguments to the PC event constructors to following methods:
addKernelFuncEvent addFuncEvent
Additionally, this changeset adds the following helper method to the System base class:
addFuncEventOrPanic - Hook a PCEvent to a symbol, panic on failure.
addKernelFuncEventOrPanic - Hook a PCEvent to a kernel symbol, panic on failure.
System implementations have been updated to use the new functionality where appropriate.

ISA: generic Linux thread info support
This patch takes the Linux thread info support scattered across different ISA implementations (currently in ARM, ALPHA, and MIPS), and unifies them into a single file.
Adds a few more helper functions to read out TGID, mm, etc.
ISA-specific information (e.g., ALPHA PCBB register) is now moved to the corresponding isa_traits.hh files.

System: Move code in initState() back into constructor whenever possible.
The change to port proxies recently moved code out of the constructor into initState(). This is needed for code that loads data into memory, however for code that setups symbol tables, kernel based events, etc this is the wrong thing to do as that code is only called when a checkpoint isn't being restored from.

MEM: Make port proxies use references rather than pointers
This patch is adding a clearer design intent to all objects that would not be complete without a port proxy by making the proxies members rathen than dynamically allocated. In essence, if NULL would not be a valid value for the proxy, then we avoid using a pointer to make this clear.
The same approach is used for the methods using these proxies, such as loadSections, that now use references rather than pointers to better reflect the fact that NULL would not be an acceptable value (in fact the code would break and that is how this patch started out).
Overall the concept of "using a reference to express unconditional composition where a NULL pointer is never valid" could be done on a much broader scale throughout the code base, but for now it is only done in the locations affected by the proxies.

SE/FS: Remove System::platform and Platform::intrFrequency.
In order for a system object to work in SE mode and FS mode, it has to either always require a platform object even in SE mode, or get rid of the requirement all together. Making SE mode carry around unnecessary/unused bits of FS seems less than ideal, so I decided to go with the second option. The platform pointer in the System class was used for exactly one purpose, a path for the Alpha Linux system object to get to the real time clock and read its frequency so that it could short cut the loops_per_jiffy calculation. There was also a copy and pasted implementation in MIPS, but since it was only there because it was there in Alpha I still count that as one use.
This change reverses the mechanism that communicates the RTC frequency so that the Tsunami platform object pushes it up to the AlphaSystem object. This is slightly less specific than it could be because really only the AlphaLinuxSystem uses it. Because the intrFrequency function on the Platform class was no longer necessary (and unimplemented on anything but Alpha) it was eliminated.
After this change, a platform will need to have a system, but a system won't have to have a platform.

MEM: Add port proxies instead of non-structural ports
Port proxies are used to replace non-structural ports, and thus enable all ports in the system to correspond to a structural entity. This has the advantage of accessing memory through the normal memory subsystem and thus allowing any constellation of distributed memories, address maps, etc. Most accesses are done through the "system port" that is used for loading binaries, debugging etc. For the entities that belong to the CPU, e.g. threads and thread contexts, they wrap the CPU data port in a port proxy.
The following replacements are made: FunctionalPort > PortProxy TranslatingPort > SETranslatingPortProxy VirtualPort > FSTranslatingPortProxy

Change ExecContext to ThreadContext. This is being renamed to differentiate between the interface used objects outside of the CPU, and the interface used by the ISA. ThreadContext is used by objects outside of the CPU and is specifically defined in thread_context.hh. ExecContext is more implicit, and is defined by files such as base_dyn_inst.hh or cpu/simple/base.hh.
Further renames/reorganization will be coming shortly; what is currently CPUExecContext (the old ExecContext from m5) will be renamed to SimpleThread or something similar.
