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.

The stdio fgetc returns the character read as an unsigned char cast to
an int.
The reason why it gets casted from unsigned char to int is because EOF
is defined as a negative value (usually -1).
At the moment in the atomicio.test we store the int in a char.
However the C standard states that the sign of a char is implementation
specific. This makes the test non portable: an architecture/ABI which
which is considering a char as a unsigned char won't compile since a
unsigned value will always be != -1 (EOF).
This is the error message you would get on a aarch64 host /w gcc/5.4.0
build/ARM/base/atomicio.test.cc:121:48:
error: comparison is always true due to limited range of data type
