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.

Virtual memory areas are used to track regions of memory which may
change over the course of execution, such as heap, stack, and mmap. It
is a high-level mimicry of Linux' memory management. VMAs are intended
to be used to support lazy allocation of physical pages to valid VMAs
as the virtual addresses are touched. Lazy allocation increases speed
of simulation for SE mode processes which, for example, mmap large
files.
The VMAs can also be queried to generate a map of the process' memory
which is used in some libraries such as pthreads.
This changeset only adds APIs for virtual memory areas. These are used
in a subsequent changeset.
