Previously, the RISC-V devices queried the system object in
SimObject::init() for the number of CPUs and the number of threads.
However, the system object doesn't actually count the number of
CPUs/threads until it runs init(). Therefore, we've just been getting
lucky in the order that the SimObject init() functions were called.
This change instead decouples these two functions and makes the number
of CPUs/threads a parameter for the RISC-V interrupt devices. This
change also updates the example config script.

Now all occurances of the THE_ISA macro which were being used to check
for anything other than the NULL_ISA have been eliminated. We still need
to be able to check whether the current ISA is the null ISA, but we
don't want to let any preprocessor checks back in which are based on
what the current ISA is.
This change removes the THE_ISA macro, and replaces it with IS_NULL_ISA
which evaluates to 1 if the ISA is null, and 0 if it isn't.

Now that we're using c++17, the type_traits with a ::value member have
a _v alias which reduces verbosity. Or on other words
std::is_integral<T>::value
can be replaced with
std::is_integral_v<T>
Make this substitution throughout the code base. In places where gem5
introduced it's own similar templates, add a V alias, spelled
differently to match gem5's internal style.
gem5: :IsVarArgs<T>::value => gem5::IsVarArgsV<T>

I don't have this header on one of the machines I build on, so this is
breaking the build for me. Removing this include seems to make the
build succeed, implying that it's not actually necessary. I looked at
the file it's used in and didn't see anything that looked like it came
from this header file.

Remove the duplicate dmaVirt calls from HSA packet processor and GPU
command processor and move them into their own class. This removes some
duplicate code and allows a DmaVirtDevice to be created which will be
useful for upcoming full system GPU commits.
The DmaVirtDevice is an abstraction of the base DmaDevice but iterates
using ChunkGenerator over virtual addresses. Classes which inherit from
DmaVirtDevice must provide a translation function to translate from
virtual address to physical address. Once translated, the physical
address is passed to DmaDevice to do the work.

In C, to refer to a type without a struct or enum tag on the type, you
need to typedef it like this:
typedef struct
{
} Foo;
Foo foo;
In C++, this is unnecessary:
struct Foo
{
};
Foo foo;
Remove all of the first form in C++ files and replace them with the
second form.

Apply the gem5 namespace to the codebase.
Some anonymous namespaces could theoretically be removed,
but since this change's main goal was to keep conflicts
at a minimum, it was decided not to modify much the
general shape of the files.
A few missing comments of the form "// namespace X" that
occurred before the newly added "} // namespace gem5"
have been added for consistency.
std out should not be included in the gem5 namespace, so
they weren't.
ProtoMessage has not been included in the gem5 namespace,
since I'm not familiar with how proto works.
Regarding the SystemC files, although they belong to gem5,
they actually perform integration between gem5 and SystemC;
therefore, it deserved its own separate namespace.
Files that are automatically generated have been included
in the gem5 namespace.
The .isa files currently are limited to a single namespace.
This limitation should be later removed to make it easier
to accomodate a better API.
Regarding the files in util, gem5:: was prepended where
suitable. Notice that this patch was tested as much as
possible given that most of these were already not
previously compiling.

There are special counters in the framebuffer that are tested during
driver initialization. The expected behavior of the counters is to
return the previously read value + 1. There is one (known) counter used
in driver initialization at a fixed BAR address offset.

The flow for Full System amdgpu is the use KVM to boot linux and begin
loading the driver module. However, the amdgpu module requires reading
the VGA ROM located at 0xc0000 in X86. KVM does not support having a
small 128KiB hole at this location, therefore we take a checkpoint and
switch to a timing CPU to continue loading the drivers before the VGA
ROM is read.
This creates a checkpoint just before the first MMIOs. This is indicated
by three interrupts being sent to the PCI device. After three interrupts
in a row are counted a checkpoint exit event occurs. The interrupt
counter is reset if a non-interrupt PCI read is seen.

As part of recent decisions regarding namespace
naming conventions, all namespaces will be changed
to snake case.
::Stats became ::statistics.
"statistics" was chosen over "stats" to avoid generating
conflicts with the already existing variables (there are
way too many "stats" in the codebase), which would make
this patch even more disturbing for the users.

sim_clock::Int became sim_clock::as_int.
"as_int" was chosen because "int" is a reserved
keyword, and this namespace acts as a selector of

Another possibility to resolve this would be to
remove the namespaces "Float" and "Int" and use
unions instead.
