MEM: Clean-up of Functional/Virtual/TranslatingPort remnants

This patch cleans up forward declarations and a member-function
prototype that still referred to the old FunctionalPort, VirtualPort
and TranslatingPort. There is no change in functionality.

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.

src/arch/sparc/vtophys.cc:
a tad bit of error checking
src/arch/sparc/vtophys.hh:
Cleanup of full-system global variables, primarily in simple_cpu.cc,
to allow multi-system simulations. (Multiple systems not yet yested
though.) Also changes to build sim_smt in full-system mode (though
with only SimpleCPU and not the full timing CPU for now).

Still to do: minimize changes in SimpleCPU code between full-system
and application modes... way too many ifdefs there. Much of the
full-system stuff moved into SimpleCPU should be put in a new System
object to allow multiprocessor simulations.

Converted last remaining modules from C to C++ (mostly in /old).
Renamed all .c files to .cc and a few .h files to .hh.

Renamed architecture-specific files in arch/$TARGET from
$TARGET.{cc,hh,def} to machine.{cc,hh,def} to get rid of pointless
intermediate files in object directory. Split exo-specific
definitions out of machine.hh into machine_exo.h.

Specifics:

In machine.def, null resource descriptors must be FUClamd_NA (and not
NA) to pass C++ type checking.

Enhanced error checking/reporting in bas
src/arch/sparc/vtophys.cc:
- Get rid of my String class, the Vector class, the bitvector class, and my
doubly linked list class.
- Convert tokenize, to_number (formerly StringToNumber) and eat_white to
function on stl strings.
- Change most cases of char * and const char * to string, or const string &
- Some formatting and style nits, but not too many.
src/arch/sparc/vtophys.cc:
simplify
src/arch/sparc/vtophys.cc:

Renamed SimpleCPU::(read|write)_(byte|half|word|qword) to just read &
write, overloaded on the type of the 'data' argument. Merged the
full-system and non-full-system implementations of these eight
original functions into two common template functions.

To support this, also renamed (read|write)[1248] on memory_object and
derivatives to just read & write, again overloaded on the type of the
'data' argument. Many of these functions could now be condensed into
a few template functions (though with a level of indirection so that
the interface can remain virtual). I did not do that though.
src/arch/sparc/vtophys.cc:
First pass at compiling with gcc 3.x. Lots of "std::" in header files,
"using namespace std" in source files. (Note policy of not putting "using"
statements in headers or before includes in sources.)

Still not able to compile with gcc 3.2.
Errors:
- Can't create an ifstream from a file descriptor anymore (breaks IniFile).
- "`class MSHR::MSHRegister' is private" errors in mshr.cc and prefetch_cache.cc:
not clear why since it's in the public part of the class declaration.
- cpu.cc:879: can't match a reference and 0 (specifically "no match for `bool ?
SimObjectParam<PipeTrace*>& : int' operator")
- pipetrace.cc: "invalid conversion from `int' to `std::_Ios_Fmtflags'"
Warnings:
- strstream now deprecated... needs some rewriting in sat_counter.hh
and hybrid_pred.hh (need to get all that code out of the headers anyway)
- trace.hh macro problem: cpp now says 'pasting "::" and "Event" does not
give a valid preprocessing token'
- major "implicit typename" issues in base/sized.hh
src/arch/sparc/vtophys.cc:
src/arch/sparc/vtophys.hh:
Implement some interval statistics for full system mode.
Create a callpal function that is called when a callpal occurs so it's easier
to manipulate the statics.
Rework the vtophys stuff to make it a bit cleaner.

Massive renaming to (almost) eliminate all md_* and MD_* names
in preparation for total exorcism of machine.def.

Most of the changes in this commit were performed with the
following perl script (perl -pi <script> <files>). A small
amount of manual fixup was needed to (mostly getting rid of
the Addr typedefs in the various memory objects now that
the former md_addr_t has that name).
