Rather than include this for some targets, set it up so we can build it
all the time via the common code. This makes it easier for targets to
opt into it when they're ready, increases build coverage, and allows us
to centralize much of the logic.
We also get to delete tconfig.h from two more targets -- they were
setting WITH_DEVICES to 0 which has the same behavior as not defining
it at all.
While the SIM_HAVE_MODEL knob is gone, we now have WITH_MODEL_P, but it
is only used by the common sim-model code. We use it to declare dummy
model lists when the arch hasn't created its own.
The "MACH" and "MODEL" names are a bit generic and collide with symbols
used by other sections of code (like h8300's opcodes). Since these are
sim-specific types, they really should have a "SIM_" prefix.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
There is an architecture-info flag for listing possible arch values, but
there is on equivalent for listing possible model values. So add the
equivalent for models.

The sim code has a lot of static initializer for options and devices, but
since they aren't using newer struct style, they have to specify a value
for every option otherwise gcc spits a lot of warnings about "missing
initializer". So add NULL/0 stubs for pointers/values.
