Python's header files set various compiler macros (e.g.,
_XOPEN_SOURCE) unconditionally. This triggers preprocessor warnings
that end up being treated as errors. The Python integration manual [1]
strongly recommends that Python.h is included before any system
header. The style guide used to mandate that Python.h is included
first in any file that needs it. This requirement was changed to
always include a source file's main header first, which ended up
triggering these errors.
This change updates the style checker to always include Python.h
before the main header file.

This patch updates the git-pre-commit hook to check the files as they
will be after the commit, instead of as they are currently, this way we
prevent the undesired situation:
- unstylish modification of a file
- stage said file for commit
- try to commit and fail due to style
- fix style, forgetting staging changes
- try to commit and fail, as although the changes staged are not
styly, the current content of the file is.

Adds a wrapper to the fix functions of the verifiers. This wrapper first
copies the original file to a backup file, then performs the fix. If an
error occurs, the backup file is used to restore the original file.
Also fixed a line-length error in verifiers.py

The style checker for spacing around control statements (ControlSpace)
and the whitespace checker (Whitespace) didn't refer to some of their
configuration variables correctly. This changeset fixes those issues.

The commit that refactored the style checkers into a new Python
package (style: Refactor the style checker as a Python package)
accidentally left a fragment of file_types.py in the old location
(util/style.py). This was caused by a race between the commit that
moved the file and Nate's commit that added a copyright header to the
file.
This commit moves the last fragment (the copyright header) and removes
the old file.

Older versions of git need the '=' to connect --diff-filter to
its argument.

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.
