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).
