This will be re-used by the flake8 linter, so moving it into mozlint for
re-useability.

Right now there are excludes defined in the linter definition (via the .yml
files), as well as excludes defined in lintargs (via the mach_commands.py).
This is a minor simplification that extends each linter definition's local
excludes with the global ones right off the bat. This just makes it a bit
easier to keep track of.

This patch makes a few changes around error handling:
1) Prints the name of the linter that produced non-json output
2) Changes the 'python not found' error to a warning (as this is not fatal)
3) Makes sure said warning only gets printed once (by moving it to the setup function)

The excluded directories aren't being properly handled in the py2/py3 compat
linters. In order for FileFinder to apply the exclusions properly they need
to either be relative to or contained by the base.
This means that currently the following will work:
./mach lint -l py2 <topsrcdir>
./mach lint -l py2 testing/mochitest
But this is broken:
./mach lint -l py2 testing
This change fixes the compat linters so exclude paths will be made relative
to the FileFinder base before passing them in. Any exclude not contained by
the base is simply discarded as it won't be relevant to that FileFinder
instance anyway.

check_compat.py was adapted from gps' check-py3-compat.py in mercurial:
https://www.mercurial-scm.org/repo/hg/file/tip/contrib/check-py3-compat.py
The py3 linter simply runs ast.parse(f) for each file being linted. Any syntax errors
are formatted as mozlint results and dumped to stdout as json. I looked into also
importing the file (using 3.5+'s importlib.util.spec_from_file_location), but there
were too many problems:
1. Lots of false positives (e.g module not found)
2. Some files seemed to run indefinitely on import
I decided to punt on importing for now, we can always investigate in a follow-up.
The py2 linter runs ast.parse(f), and also checks that the file has:
from __future__ import absolute_import, print_function
Initially every python file in the tree is excluded from the py2 check, though
at least this makes it easy to find+fix, and new files in un-excluded
directories will automatically be linted.
