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 an AbstractRepo class and implementations for git and Mercurial
that provide a common interface to query repository status for style
checkers. The class defines the interfaces to list modified files that
are about to be committed and methods to identify changed regions.

Style validators provide a subset of the style verifier functionality
and are only exposed through the "hg m5format" command. This
functionality seems to be both redundant and unused.

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.
