Back when the class was written, for the packaging code, it made sense
that the default was True. But now that it's used all over the place,
and that the vast majority of uses are with find_executables=False, it
makes more sense for that to be the default.

This is an educated guess in an attempt to solve a hard to reproduce intermittent. This
also makes sure the original SIGINT handler is restored after running the linters.

This deprecates PYTHON_UNIT_TESTS and replaces it with PYTHON_UNITTEST_MANIFESTS.
In the build system, this means python unittests will be treated the same as all
other test suites that use manifestparser. New manifests called 'python.ini' have
been created for all test directories containing python unittests.

This replaces the "return_code" property on the LintRoller object with a list of "failed"
linters. This is a bit more useful as it lets us know exactly which linters had a problem
(whereas previously we just knew *something* went wrong). This patch pushes determining
the return code back into cli.py, which I think is fine.
In addition, we now pass the list of failed linters into the formatter. This allows us to
clarify exactly how many linters hit a failure which is a lot better than a seemingly
"successful" summary message.
Finally I also removed the "no files to lint" message because I've seen several people
confuse it for an error. I'll probably add it back as a debug log message when we switch
to using mozlog for output.

If a linter returns a status code instead of a list of results, mozlint will throw away
that status code and move on to the next linter. We should make sure that status code
bubbles all the way up to the cli.

Versions of mercurial older than 3.0 don't support the -T shorthand for
the --template option. While most people should be using something
newer, it can still happen that some run an older version, and it's
still trivial to support them by using the long option.

This is mostly to maintain backwards compatibility with the |mach eslint| command. But it's also going to be used in
automation. The 'mozlint-eslint' task will need to pass in --quiet to eslint.
Maybe in the future we should remove this ability and only allow well-defined arguments in mozlint. But for now it's
convenient and allows us to land the eslint->mozlint patch series quicker.

Some linters, such as flake8, will lint invalid file extensions if you explicitly pass them in. E.g,
|flake8 foobar.js| will result in flake8 attempting to lint a JS file. This is a problem because passing
in files explicitly is exactly what the --rev/--workdir options do. If a developer modifies a JS file
then runs |mach lint -l flake8 -w|, that JS file will get linted.
To prevent this, mozlint needs to handle file extensions instead of relying on the underlying linter to
do it. This patch adds an "extensions" config option to the LINTER dict, and will filter these files out
as part of the 'filterpaths' steps.

It's important to use absolute paths so lint errors for the same files don't show up in two
different places. For example, eslint will absolutize a relative path, whereas flake8 will
not.
This patch also makes sure all include/exclude paths are joined to the mozlint 'root' that
was previously calculated from vcs.

Previously, vcs related stuff was resolved in the cli.py module. But it's possible
for consumers to bypass the cli and instantiate a LintRoller directly. In fact this
is what the mozlint tests do.
Now that we always try to find the vcs root, calling into vcs is no longer optional.
This patch moves the VCSFiles class to a new vcs.py module and makes LintRoller
responsible for instantiating it instead of cli.py.

This adds two parameters, --rev and --workdir. Each works both with mercurial and git (though the syntax for
specifying revisions is different between them). The value is simply forwarded to either |hg log| or |git diff|
so syntax like |mach lint -r .~4::.| or |mach lint -r "HEAD~4 HEAD"| will work as expected.

There is currently no built-in user interface to mozlint. The only existing interface is the
external cli provided by |mach lint|. However, in the future mozlint may need to be used in a
context where mach isn't readily available (i.e version-control-tools). This patch basically
just moves the cli logic out of mach_commands.py, and into mozlint core. That way it can be
re-used in other places without needing to be re-implemented.
The |mach lint setup| subcommand was removed because apparently subcommands don't work with
the parser attribute. Nothing was using it yet anyway, so I removed it for now. It may get
re-added in some form in the future.

Currently a bug in python (https://bugs.python.org/issue8296) is preventing a KeyboardInterrupt from
reaching the parent process, meaning we can't kill the process with SIGINT. There is a workaround to
this bug, but instead I decided to ignore SIGINT in the parent process completely. Now, each child
process is responsible for handling SIGINT on its own. Since child processes should all shutdown
relatively quickly anyway, this effectively also ends the parent process.
The benefit of doing it this way is that each child process can return the results they have collected
to date. So when a developer hits Ctrl-C, they'll still see some (but not all) formatted lint output.
The downside is that a poorly implemented external linter could block the parent process from exiting
quickly, but if this happens we should just fix the linter.

For now, only the following two directories will be linted:
python/mozlint
tools/lint
New directories can be added by adding them to the 'include'
directive in tools/lint/flake8.lint. They all default to the
configuration specified in topsrcdir/.flake8. Subdirectories
can override this configuration by creating their own .flake8
file.

The current algorithm for filtering down tests is too naive. For example, given the following
directory structured:
parent
- foo
- bar
- baz
And the following include/exclude directives:
include = ['foo']
exclude = ['foo/bar']
Then running ./mach lint parent and ./mach lint foo/baz should both lint all files in baz but
no files in bar. This provides a nice way to include/exclude directories, while allowing the
underlying linters to find appropriate files to lint *within* those directories.
tl;dr - Straight file paths (no globs) will be passed straight to the underlying linter as is.
While paths with globs will first be resolved to a list of matching file paths.

Mozlint provides two main benefits:
1. A common system for defining lints across multiple languages
2. A common interface and result format for running them
