974a47dfb9 misc: Adopt the gem5 namespace
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.

773368d68d arch-arm: Consolidate register related files into a directory.
Create a directory called "regs" which holds files, primarily headers,
related to registers, with the exception of registers.hh. Hopefully
registers.hh will go away in the not too distant future, removing this
exception.

8633b87f15 arch: Move setting up RegClassInfos into the arches.
Also remove no longer global constants from arch/registers.hh if they
are no longer used locally.

774770a641 arm: Get rid of some register type definitions.
These are IntReg, FloatReg, FloatRegBits, and MiscReg. These have been
supplanted by the global types RegVal and FloatRegVal.

1088f0c4ac misc: Rename misc.(hh|cc) to logging.(hh|cc)
These files aren't a collection of miscellaneous stuff, they're the
definition of the Logger interface, and a few utility macros for
calling into that interface (panic, warn, etc.).

899ad72060 arch, arm: Print value being ignored on DummyISA write
When ignoring writes to the Dummy ISA device (DummyISADevice),
additionally print the value being ignored in the diagnostic.

Sometimes it is useful to know exactly what we are dropping ...

070b4a81db arm: Add support for filtering in the PMU
This patch adds support for filtering events in the PMU. In order to
do so, it updates the ISADevice base class to forward an ISA pointer
to ISA devices. This enables such devices to access the MiscReg file
to determine the current execution level.

3697990c27 arm: Add a model of an ARM PMUv3
This class implements a subset of the ARM PMU v3 specification as
described in the ARMv8 reference manual. It supports most of the
features of the PMU, however the following features are known to be
missing:

 * Event filtering (e.g., from different privilege levels).
 * Access controls (the PMU currently ignores the execution level).
 * The chain counter (event no. 0x1E) is unimplemented.

The PMU itself does not implement any events, it merely provides an
interface for the configuration scripts to hook up probes that drive
events. Configuration scripts should call addEventProbe() to configure
custom events or high-level methods to configure architected
events. The Python implementation of addEventProbe() automatically
delays event type registration until after instantiation.

In order to support CPU switching and some combined counters (e.g.,
memory references synthesized from loads and stores), the PMU allows
multiple probes per event type. When creating a system that switches
between CPU models that share the same PMU, PMU events for all of the
CPU models can be registered with the PMU.

Kudos to Matt Horsnell for the initial gem5 implementation of the PMU.
