37495f8823 misc: Using OS::size_t in syscall signature 
Using the host size_t is confusing the guest ABI engine every time
the host and the guest adopt a different data model (ILP32 vs LP64)

For example when a LP64 machine is running an ILP32 application in SE
mode, "size_t" will wrongly inform the guest ABI engine to retrieve the
argument by loading a 64 bit (instead of 32) value from the stack

83b14e569b misc: Stop using getVirtProxy. 
The proxies are not used on the critical path, and it's usually implicit
whether they should be the FS or SE version.

Ideally in the future we won't need to worry about which version we need
to use, but the differences haven't quite been abstracted away, and
occasionally we need to decide between the two.

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.

naming conventions, all namespaces will be changed
