The style checker code needs to disable autojunk when diffing source
files using Python's difflib. Support for this was only introduced in
Python 2.7, which leads to a TypeError exception on older Python
version. This changeset adds a fallback mechanism for old Python
versions.
The old style guide used to mandate 78 characters as the maximum line
length to accommodate traditional diffs on 80-column terminals. This
is an uncommon use case and it has therefore been decided (see email
thread on gem5-dev [1]) that a maximum length of 79-characters makes
more sense.

Add a style checker that verifies that source code doesn't contain
non-printable (control) characters. The only allowed control
characters are:
* 0x0a / \n: New line
* 0x09 / \t: Tab (the whitespace checker enforces no-tabs for C/C++ files)

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.
