Add an option, --checker/-c, to style.py that selects individual style
checkers to apply. When this option isn't specified, the script
defaults to all available style checkers. The option may be specified
multiple times to run multiple style checkers.
The option, --fix/-f, can be specified to automatically fix style
violations.

The current style checker script, hgstyle.py, assumes that it is being
run from Mercurial. This means that it depends on the Mercurial Python
libraries, which aren't necessarily present if using git. This
changeset adds a new style checker script, style.py, that has
been designed to be run from the command line.
The script has support for detecting which revision control system is
used and is able to query both git and Mercurial for changes. This
enables the script to operate on modified regions and/or all of the
modified files in the repository.

The Mercurial style checker extensions are currently stored in
style.py. This is not ideal since they won't work with other version
control systems. This changeset renames style.py to hgstyle.py and
adds upgrade code to scons that automatically updates the hooks in
hgrc.

Remove the unsupported style.py subcommands (fixwhite, chkwhite),
which leaves the chkformat command as the only remaining
command. Since the script now only supports one command, remove the
sub-command support altogether.

The style checker incorrectly includes newlines when checking lines of
code, which effectively decreases the column limit by 1. This
changeset strips the newline character from before calling line
checkers.

Added checkers for line length and boolean comparisons
(== true/== false) to the style script.

Added a new Verifier object to check for and fix spacing
between if/while/for and following paren.
Restructured Verifier class to make it easier to add
new subclasses, particularly by using a global list of
verifiers to auto-generate command line options and
simplify the invocation loop.

The m5format command didn't actually work due to parameter handling
issues and missing language detection. This changeset fixes those
issues and cleans up some of the code to shared between the style
checker and the format checker.

The style used to support the option -w to automatically fix white
space issues. However, this option was actually wired up to fix all
styles issues the checker encountered. This changeset cleans up the
code that handles automatic fixing and adds an option to fix all
issues, and separate options for white spaces and include ordering.

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 some directories within the repository where we don't want
to enforce our coding style. Specifically, we don't want the style
hooks to warn whenever we update external code in the ext/ directory.

The 'hg m5style' command had some rather strange semantics. When
called without arguments, it applied the style checker to all added
files and modified regions of modified files. However, when providing
a list of files, it used that list as an ignore list instead of
specifically checking those files.
This patch makes the m5style command behave more like other Mercurial
commands where the arguments are used to specify which files to work
on instead of which files to ignore.

The style checker used to traverse symlinks if they pointed to files, which can
result in style checker failure if the pointed-to file doesn't exist. This
style check is actually unnecessary, since symlinks either point to other files
that are already style checked, or files outside gem5, which shouldn't be
checked. Skip symlinks.

I've renamed the check_whitespace operation to check_style. You're going to
need to change your .hg/hgrc file. While you're at it, add a pre-qrefresh
hook please.

clean up the code a little bit while we're at it.
I recommend that everyone adds the pre-qrefresh hook below since it
will make qref run the style hook and not just commit/qpush
[extensions]
style = <m5 path>/util/style.py
[hooks]
pretxncommit.style = python:style.check_whitespace
pre-qrefresh.style = python:style.check_whitespace

Before this fix, the style hook would blow up when you did a qrefresh to add
a new file, but executed the qrefresh from a repository sub directory.
