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.

71460cb13e sim,misc: Rename Int namespace as as_int
As part of recent decisions regarding namespace
naming conventions, all namespaces will be changed
to snake case.

sim_clock::Int became sim_clock::as_int.

"as_int" was chosen because "int" is a reserved
keyword, and this namespace acts as a selector of
how to read the internal variables.

Another possibility to resolve this would be to
remove the namespaces "Float" and "Int" and use
unions instead.

5c8983fc18 misc: Fix remaining opening braces
These were not caught by the previous patches because
the grep used ignored:
- anonymous structures
  (e.g., "struct {")
- opening braces without leading spaces
  (e.g., "struct Name{"),
- weird chars in auto-generation files
  (e.g., "struct $name {").
- extra characters after the opening brace.
  (e.g., "struct Name { // Comment")
- typedefs (note that this is not caught by the verifier)
  (e.g., "typedef struct Name {")

Most of this has been fixed be grepping structures
with the following regex:
  grep -nrE --exclude-dir=systemc \
    "^ *(typedef)* *(struct|class|enum|union) [^{]*{$" src/

The following makes sure that "struct{" is captured:
  grep -nrE --exclude-dir=systemc \
    "^ *(struct|class|enum|union){" src/

To find cases that contain a comment after the
opening brace:
  grep -nrE --exclude-dir=systemc \
    "^ *(struct|class|enum|union)[^{]*{\s*//" src/

415abb3a3c sim,mem,dev: Merge eventq_impl.hh into eventq.hh.
Having some methods (which are supposed to be inline) defined in another
file which is only included sometimes creates a lot of opportunities for
errors. They no longer need to be separate, so merge them together.

89f2d5eb54 misc: Make many includes explicit.
A future change will adjust how some includes can be included
transitively. This change fixes up those files so that they include the
headers they need directly, instead of expecting to have them by
accident through other files.

a928a438b8 style: [patch 3/22] reduce include dependencies in some headers
Used cppclean to help identify useless includes and removed them. This
involved erroneously included headers, but also cases where forward
declarations could have been used rather than a full include.

76cd4393c0 sim: Refactor the serialization base class
Objects that are can be serialized are supposed to inherit from the
Serializable class. This class is meant to provide a unified API for
such objects. However, so far it has mainly been used by SimObjects
due to some fundamental design limitations. This changeset redesigns
to the serialization interface to make it more generic and hide the
underlying checkpoint storage. Specifically:

  * Add a set of APIs to serialize into a subsection of the current
    object. Previously, objects that needed this functionality would
    use ad-hoc solutions using nameOut() and section name
    generation. In the new world, an object that implements the
    interface has the methods serializeSection() and
    unserializeSection() that serialize into a named /subsection/ of
    the current object. Calling serialize() serializes an object into
    the current section.

  * Move the name() method from Serializable to SimObject as it is no
    longer needed for serialization. The fully qualified section name
    is generated by the main serialization code on the fly as objects
    serialize sub-objects.

  * Add a scoped ScopedCheckpointSection helper class. Some objects
    need to serialize data structures, that are not deriving from
    Serializable, into subsections. Previously, this was done using
    nameOut() and manual section name generation. To simplify this,
    this changeset introduces a ScopedCheckpointSection() helper
    class. When this class is instantiated, it adds a new /subsection/
    and subsequent serialization calls during the lifetime of this
    helper class happen inside this section (or a subsection in case
    of nested sections).

  * The serialize() call is now const which prevents accidental state
    manipulation during serialization. Objects that rely on modifying
    state can use the serializeOld() call instead. The default
    implementation simply calls serialize(). Note: The old-style calls
    need to be explicitly called using the
    serializeOld()/serializeSectionOld() style APIs. These are used by
    default when serializing SimObjects.

  * Both the input and output checkpoints now use their own named
    types. This hides underlying checkpoint implementation from
    objects that need checkpointing and makes it easier to change the
    underlying checkpoint storage code.

2d6470936c sim: have a curTick per eventq
This patch adds a _curTick variable to an eventq. This variable is updated
whenever an event is serviced in function serviceOne(), or all events upto
a particular time are processed in function serviceEvents(). This change
helps when there are eventqs that do not make use of curTick for scheduling
events.

ffb6aec603 AddrRange: Transition from Range<T> to AddrRange
This patch takes the final plunge and transitions from the templated
Range class to the more specific AddrRange. In doing so it changes the
obvious Range<Addr> to AddrRange, and also bumps the range_map to be
AddrRangeMap.

In addition to the obvious changes, including the removal of redundant
includes, this patch also does some house keeping in preparing for the
introduction of address interleaving support in the ranges. The Range
class is also stripped of all the functionality that is never used.

It's not the right fix for the checkpoint deadlock problem
Brad was having, and creates another bug where the system can
deadlock on restore.  Brad can't reproduce the original bug
right now, so we'll wait until it arises again and then try
to fix it the right way then.

283be34a99 devices: Fixed periodic interrupts to work with draining
Added drain functions to the RTC and 8254 timer so that periodic interrupts
stop when the system is draining.  This patch is needed to checkpoint in
timing mode.  Otherwise under certain situations, the event queue will never
be completely empty.
