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.

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.

to snake case.
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
how to read the internal variables.
Another possibility to resolve this would be to
remove the namespaces "Float" and "Int" and use
unions instead.

These classes belong in the ps2 namespace. Use this
opportunity to rename PS2Device as ps2::Device, and
PS2TouchKit as ps2::TouchKit.
Unfortunately, since the ps2::Mouse and ps2::Keyboard
namespaces are being deprecated, these names cannot be
used as of now to rename PS2Mouse and PS2Keyboard.

The VExpress_GEM5_Foundation platform was reserving
a region of the memory map (@ 0x4 0000 0000) for PCI.
The Armv8-A FVP Foundation platform is not PCI capable at
the moment, so any PCI logic is really gem5 specific.
With this patch we are aligning gem5 to the FVP Base Platform,
which supports PCI and it is reserving 256GiB of memory
starting at 0x40 0000 0000 (256GiB).
Fast Models - Reference Manual - Version 11.8
At the moment we are still supporting a single DRAM range,
starting at 2GiB. So DRAM could overlap with the PCI memory
region though it is unlikely to happen in near future as
it would require a DRAM size > 254 GiB.

These were not caught by the previous patches because
the grep used ignored:
- anonymous structures
(e.g., "struct {")
- opening braces without leading spaces
(e.g., "struct Name{"),
- weird chars in auto-generation files
(e.g., "struct $name {").
- extra characters after the opening brace.
(e.g., "struct Name { // Comment")
- typedefs (note that this is not caught by the verifier)
(e.g., "typedef struct Name {")
Most of this has been fixed be grepping structures
with the following regex:
grep -nrE --exclude-dir=systemc \
"^ *(typedef)* *(struct|class|enum|union) [^{]*{$" src/
The following makes sure that "struct{" is captured:
grep -nrE --exclude-dir=systemc \
"^ *(struct|class|enum|union){" src/
To find cases that contain a comment after the
opening brace:
grep -nrE --exclude-dir=systemc \
"^ *(struct|class|enum|union)[^{]*{\s*//" src/

This function causes problems with gcc 5 which incorrectly complains
about the call to warn_if inside a constexpr function. That should only
be an error if a call to a non-constexpr is unavoidable, and even then
the compiler isn't required to emit a diagnostic.
Rather than drop the warning, or add ifdefs to deal with these defective
versions of gcc, this change eliminates the power() function entirely.
Most inputs to this function would overflow anyway, which is reportedly
why no integer version of an exponentiation function is defined in the
standard library, and all uses of this function can easily and more
efficiently be replaced by simple left and right shifts.
Finally, by eliminating the power() function, we also remove the
dependence on base/logging.hh.

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

The mismatches were from places where Params structs had been declared
as classes instead of structs, and ruby's MachineID struct.
A comment describing why the warning had been disabled said that it was
because of libstdc++ version 4.8. As far as I can tell, that version is
old enough to be outside the window we support, and so that should no
longer be a problem. It looks like the oldest version of gcc we
support, 5.0, corresponds with approximately libstdc++ version 6.0.21.
