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
This commit only adds the core library, it does not add any consumers of mozlint just yet.
