System object now exists for both fullsys and syscall emulation, as the
latter needs it so that Process objects can find the shared PhysicalMemory
for initialization.
Changes are incomplete: still need to fix up Process (& EioProcess) memory
initialization and syscall emulation code for new mem interface.

cpu/base.hh:
Take System argument in constructor.
cpu/exec_context.cc:
Take System argument in constructor.
Merge two constructors into a single one.
cpu/exec_context.hh:
Take System argument in constructor.
Merge two constructors into a single one.
Replace dummy translation with lookup in Process object's page table.
python/m5/objects/Process.py:
Add System parameter to Process object (& subobjects).
python/m5/objects/System.py:
Segregate full-system only Process parameters (most of them!).
sim/process.cc:
Take System argument in constructor.
Move initialization to startup() callback to occur after system & cpus
are initialized.
Generate ProxyMemory object to pass to loader for transparent
virtual page allocation.
sim/process.hh:
Take System argument in constructor.
Move initialization to startup() callback to occur after system & cpus
are initialized.
sim/system.cc:
sim/system.hh:
Enable System object for non-full-system too.
Basically involved putting most of the existing code
inside '#ifdef FULL_SYSTEM'.
Key thing needed for syscall emulation at this point is
the PhysicalMemory object (for Process initialization).

interfaces, and specific support for Alpha Linux. Split syscall emulation
functions into several groups, based on whether they depend on the specific
OS and/or architecture (and all combinations of above), including the use of
template functions to support syscalls with slightly different constants
or interface structs.
arch/alpha/alpha_tru64_process.cc:
Incorporate full Tru64 object definition here, including structure and constant definitions.
This way we can wrap all of the functions inside the object, and not worry about namespace
conflicts because no one outside this file will ever see it.

prog.hh is now process.hh

prog.hh is now process.hh
move architecture-specific syscall arg accessors into ExecContext
cpu/simple_cpu/simple_cpu.cc:
No need to include prog.hh (which has been renamed)
sim/process.cc:
sim/process.hh:
LiveProcess is now effectively an abstract base class.
New LiveProcess::create() function takes an object file and dynamically picks the
appropriate subclass of LiveProcess to handle the syscall interface that file expects
(currently Tru64 or Linux).
