Refactor the style checker into a Python module that can be reused by
command line tools that integrate with git. In particular:
* Create a style package in util
* Move style validators from style.py to the style/validators.py.
* Move style verifiers from style.py to the style/verifiers.py.
* Move utility functions (sort_includes, region handling,
file_types) into the style package
* Move generic code from style.py to style/style.py.

The include sorter class normally yields one string per line and
relies on the caller to merge lines into a block of text separated by
newlines. However, there are cases when this isn't true. This makes
diffing using Python's difflib hard. This changeset updates the
include sorter to never do this and always yield one line at a time.

The following changes introduced substantial changes to sort_includes.py:
- hg:84b4d6af0ecc - util: Fix state leakage in ...

Since the file didn't include a copyright header at the time, I never
added the correct ARM copyright notice. This changeset adds the
correct copyright notice.

As of August 2014, the gem5 style guide mandates that a source file's
primary header is included first in that source file. This helps to
ensure that the header file does not depend on include file ordering
and avoids surprises down the road when someone tries to reuse code.
In the new order, include files are grouped into the following blocks:
* Primary header file (e.g., foo.hh for foo.cc)
* Python headers
* C system/stdlib includes
* C++ stdlib includes
* Include files in the gem5 source tree
Just like before, include files within a block are required to be
sorted in alphabetical order.
This changeset updates the style checker to enforce the new order.

There are cases where the state of a SortIncludes object gets messed
up and leaks between invocations/files. This typically happens when a
file ends with an include block (dump_block() gets called at the end
of __call__). In this case, the state of the class is not reset
between files. This bug manifests itself as ghost includes that leak
between files when applying the style hooks.
This changeset adds a reset at the beginning of the __call__ method
which ensures that the class is always in a clean state when
processing a new file.

I didn't realize that the perl version existed when I started this,
this version has a lot more features than the previous one since it will
sort and separate python, system, and m5 headers in separate groups, it
will remove duplicates, it will also convert c headers to stl headers
