The patch is using the newly defined PARAMS macro to replace
custom params() getters in derived class.
The patch is also removing redundant _params:
Instead of creating yet another _params field, SimObject descendants
should use params() to expose the real type of SimObject::_params they
already have.

The create() method on Params structs usually instantiate SimObjects
using a constructor which takes the Params struct as a parameter
somehow. There has been a lot of needless variation in how that was
done, making it annoying to pass Params down to base classes. Some of
the different forms were:
const Params &
Params &
Params *
const Params *
Params const*
This change goes through and fixes up every constructor and every
create() method to use the const Params & form. We use a reference
because the Params struct should never be null. We use const because
neither the create method nor the consuming object should modify the
record of the parameters as they came in from the config. That would
make consuming them not idempotent, and make it impossible to tell what
the actual simulation configuration was since it would change from any
user visible form (config script, config.ini, dot pdf output).

Two python Enum parameter types had some very generic elements which
both include one named "none". When headers for both are included that
creates a conflict which breaks the build. Enums which such extremely
generic names need to be scoped so that they don't invite these sorts
of collisions.
This change converts them from Enum to ScopedEnum in python, and also
makes a few small changes to where they're used in c++ to match.

The importer in Python 3 doesn't like the way we import SimObjects
from the global namespace. Convert the existing SimObject declarations
to import from m5.objects. As a side-effect, this makes these files
consistent with configuration files.

Generally speaking, the endianness of the data devices provide or
accept is dependent on the device and not the ISA the system
executes. This change makes the devices in dev pick an endianness
rather than using the guest's.
For the ISA bus and the UART, accesses are byte sized and so endianness
doesn't matter. The ISA and PCI busses and the devices which use them
are defined to be little endian.

When running gem5, the simulator outputs the following message to
describe the ports used by the VNC server and ther terminal:
Listening for system connection on port 5900
Listening for system connection on port 3456
The code used to extract the basename ('terminal' or 'vncserver') and
print that instead of system. However, this doesn't seem to work any
more. Change the code to output the full object name instead.

Add a simple memory-mapped device that forwards writes to a serial
devices and treats reads as reads from the device. Unlike real UART
models, this one doesn't support interrupts.
This is useful to implement various debug devices that exist in many
systems.
