SE: move page allocation from PageTable to Process
PageTable supported an allocate() call that called back
through the Process to allocate memory, but did not have
a method to map addresses without allocating new pages.
It makes more sense for Process to do the allocation, so
this method was renamed allocateMem() and moved to Process,
and uses a new map() call on PageTable.
The remaining uses of the process pointer in PageTable
were only to get the name and the PID, so by passing these
in directly in the constructor, we can make PageTable
completely independent of Process.

SimObject: add export_method* hooks to export C++ methods to Python
Replace the (broken as of previous changeset) swig_objdecl() method
that allowed/forced you to substitute a whole new C++ struct
definition for SWIG to wrap with a set of export_method* hooks
that let you just declare a set of C++ methods (or other declarations)
that get inserted in the auto-generated struct.
Restore the System get/setMemoryMode methods, and use this mechanism
to specialize SimObject as well, eliminating teh need for sim_object.i.
Needed bits of sim_object.i are moved to the new pyobject.i.
Also sucked a little SimObject specialization into cxx_param_decl()
allowing us to get rid of src/sim/sim_object_params.hh. Now the
generation and wrapping of the base SimObject param struct is more
in line with how derived objects are handled.
--HG--
rename : src/python/swig/sim_object.i => src/python/swig/pyobject.i

scons/swig: refactor some of the scons/SWIG code
- Move the random bits of SWIG code generation out of src/SConscript
file and into methods on the objects being wrapped.
- Cleaned up some variable naming and added some comments to make
the process a little clearer.
- Did a little generated file/module renaming:
- vptype_Foo now Foo_vector
- init_Foo is now Foo_init
This makes it easier to see all the Foo-related files in a
sorted directory listing.
- Made cxx_predecls and swig_predecls normal SimObject classmethods.
- Got rid of swig_objdecls hook, even though this breaks the System
objects get/setMemoryMode method exports. Will be fixing this in
a future changeset.

Faults: Add in generic faults that work like panics, warns, etc.
These faults take varargs to their constructors which they print into a string

All of the classes will now be available in both modes, and only
GenericPageTableFault will continue to check the mode for conditional

for now those aren't available in FS mode.

ISA parser: Use '_' instead of '.' to delimit type modifiers on operands.
By using an underscore, the "." is still available and can unambiguously be
used to refer to members of a structure if an operand is a structure, class,
etc. This change mostly just replaces the appropriate "."s with "_"s, but
there were also a few places where the ISA descriptions where handling the
extensions themselves and had their own regular expressions to update. The
regular expressions in the isa parser were updated as well. It also now
looks for one of the defined type extensions specifically after connecting "_"
where before it would look for any sequence of characters after a "."
following an operand name and try to use it as the extension. This helps to
disambiguate cases where a "_" may legitimately be part of an operand name but
not separate the name from the type suffix.
Because leaving the "_" and suffix on the variable name still leaves a valid
C++ identifier and all extensions need to be consistent in a given context, I
considered leaving them on as a breadcrumb that would show what the intended
type was for that operand. Unfortunately the operands can be referred to in
code templates, the Mem operand in particular, and since the exact type of Mem
can be different for different uses of the same template, that broke things.

LSQ: Moved a couple of lines to enable O3 + Ruby
This patch makes O3 CPU work along with the Ruby memory model. Ruby
overwrites the senderState pointer with another pointer. The pointer
is restored only when Ruby gets done with the packet. LSQ makes use of
senderState just after sendTiming() returns. But the dynamic_cast returns
a NULL pointer since Ruby's senderState pointer is from a different class.
Storing the senderState pointer before calling sendTiming() does away with
the problem.
