As part of recent decisions regarding namespace
naming conventions, all namespaces will be changed
to snake case.
X86Macroop became x86_macroop.
Ideally, this should probably be moved to inside the
X86ISA namespace, and renamed accordingly, but a macroop
namespace would probably generate a lot of conflicts.

Clang 11 threw the following error: `anonymous non-C-compatible type
given name for linkage purposes by typedef declaration; add a tag name
here`.
Clang 11 enforces a restriction on giving non-C-compatible anonymous
structs a typedef name for linking purposes. This change to the C++
standard is discussed here http://wg21.link/p1766r1 and has been
retroactively applied to all C++ standard versions.

This is patch is in regard to issues discussed here:
https://www.mail-archive.com/gem5-dev@gem5.org/msg39122.html
The aim of this patch is to set a potential fix, and to give more
valuable debugging information.
It is not known why Kokoro sometimes fails, but it may be due to the
Docker service not starting fully prior to execution of the tests
within a Docker container. As such a 2 second sleep has been added
between starting the Docker service and running the tests.
The pulling of the docker images has been separated out to run at the
start of testing. This should help us determine whether the issue lays
with the pulling of an image or the running of a container.
The bash debug flag `-x` has been set so the expansion of each line can
be determined upon the event of a failure.
This patch will be reverted if it is found to not solve the issue.

In this context, the decoder width is the number of bytes that are fed
into the decoder at once. This is frequently the same as the size of an
instruction, but in instructions with occasionally variable instruction
sizes (ARM, RISCV), or extremely variable instruction sizes (x86) there
may be no relation.
Rather than determining the amount of data to feed to the decoder based
on a MachInst type defined by each ISA, this new interface adds some new
properties to the base InstDecoder class each arch specific decoder
inherits from. These are the size of the incoming buffer, a pointer to
wherever that data should end up, and a mask for masking a PC value so
it aligns with the instruction size.
These values are filled in by a templated InstDecoder constructor which
is templated based on what would have historically been the MachInst
type.
Because the "moreBytes" method would historically accept a parameter of
type MachInst, this parameter has also been eliminated. Now, the
decoder's parent object should use the pointer and size values to fill
in the buffer moreBytes reads. Then when moreBytes is called, it just
uses the buffer without having to show what its type is externally.

The existing template would apply the helper operator to *any* template
which took two types, regardless of what that template was. The
assumption was that those types *must* be STL containers, because no
other template takes two types, right?
Instead, this new version uses type traits to explicitly whitelist types
which the helper applies to. Currently the only type it seems to be used
with is std::vector, but by defining more specializations of
IsHelpedContainer, other types/templates can be enabled as well.
This is particularly important when moving to c++17, since the
std::string class would then apparently match the old overload. That
makes the << operator ambiguous and breaks the build.

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.

Debug flags were directly declared as global objects; however, the
destruction order of global objects in different translation units are
not defined in c++, so the destructor of other objects cannot safely
utilize debug flags to output extra information.
We now define those flags as references to objects allocated on the heap
so our flags will never get destructed. Note that this won't really
introduce any memory leak, as the program is getting terminated anyway.

This can be used to send a functional packet from the perspective of a
thread context. Currently this will not consider targets within the CPU
like the local APIC on x86. The default implementation sends a packet
using the port on the way out of the CPU.

These versions of g++ don't handle parameter pack expansion correctly
when there is a parameter pack defined at the class level and then one
which is defined by the constructor itself. Even though it knows what
the outter parameter pack contains, it still re-assigns it to be empty
and puts all arguments into the later parameter pack.
To work around this problem, we will explicitly put the class level
parameters into a tuple, which we then have to go through extra
acrobatics to explode and pass into base class constructors.
That also means that in all subclasses, the arguments which go into the
tuple need to be wrapped in {}s to group them into constructor arguments
for the tuple.
