Update pylint to 1.8.3

[pyup-bot]

This PR updates pylint from 1.7.2 to 1.8.3.

Changelog

1.8.1

=========================

Release date: 2017-12-15

 * Wrong version number in __pkginfo__.

1.8

=========================

Release date: 2017-12-15

 * Respect disable=... in config file when running with --py3k.

 * New warning `shallow-copy-environ` added

   Shallow copy of os.environ doesn't work as people may expect. os.environ
   is not a dict object but rather a proxy object, so any changes made
   on copy may have unexpected effects on os.environ

   Instead of copy.copy(os.environ) method os.environ.copy() should be
   used.

   See https://bugs.python.org/issue15373 for details.

 * Do not display no-absolute-import warning multiple times per file.

 * `trailing-comma-tuple` refactor check now extends to assignment with
    more than one element (such as lists)

   Close 1713

 * Fixing u'' string in superfluous-parens message

   Close 1420

 * `abstract-class-instantiated` is now emitted for all inference paths.

    Close 1673

 * Add set of predefined naming style to ease configuration of checking
   naming conventions.

   Closes 1013

 * Added a new check, ``keyword-arg-before-vararg``

   This is emitted for function definitions
   in which keyword arguments are placed before variable
   positional arguments (*args).

   This may lead to args list getting modified if keyword argument's value
   is not provided in the function call assuming it will take default value
   provided in the definition.

 * The `invalid-name` check contains the name of the template that caused the failure

   Close 1176

 * Using the -j flag won't start more child linters than needed.

 * Fix a false positive with bad-python3-import on relative imports

   Close 1608

 * Added a new Python 3 check, ``non-ascii-bytes-literals``

   Close 1545

 * Added a couple of new Python 3 checks for accessing dict methods in non-iterable context

 * Protocol checks (not-a-mapping, not-an-iterable and co.) aren't emitted on classes with dynamic getattr

 * Added a new warning, 'bad-thread-instantiation'

   This message is emitted when the threading.Thread class does not
   receive the target argument, but receives just one argument, which
   is by default the group parameter.

   Close 1327

 * In non-quiet mode, absolute path of used config file is logged to
   standard error.
   Close 1519

 * Raise meaningful exception for invalid reporter class being selected

   When unknown reporter class will be selected as Pylint reporter,
   meaningful error message would be raised instead of bare ``ImportError``
   or ``AttribueError`` related to module or reporter class being not found.
   Close 1388

 * Added a new Python 3 check for accessing removed functions from itertools
   like ``izip`` or ``ifilterfalse``

 * Added a new Python 3 check for accessing removed fields from the types
   module like ``UnicodeType`` or ``XRangeType``

 * Added a new Python 3 check for declaring a method ``next`` that would have
   been treated as an iterator in Python 2 but a normal function in Python 3.

 * Added a new key-value pair in json output. The key is ``message-id``
   and the value is the message id.
   Close 1512

 * Added a new Python 3.0 check for raising a StopIteration inside a generator.
   The check about raising a StopIteration inside a generator is also valid if the exception
   raised inherit from StopIteration.
   Close 1385

 * Added a new warning, ``raising-format-tuple``, to detect multi-argument
   exception construction instead of message string formatting.

 * Added a new check for method of logging module that concatenate string via + operator
   Close 1479

 * Added parameter for limiting number of suggestions in spellchecking checkers

 * Fix a corner-case in ``consider-using-ternary`` checker.

   When object ``A`` used in  ``X and A or B`` was falsy in boolean context,
   Pylint incorrectly emitted non-equivalent ternary-based suggestion.
   After a change message is correctly not emitted for this case.
   Close 1559

 * Added ``suggestion-mode`` configuration flag. When flag is enabled, informational
   message is emitted instead of cryptic error message for attributes accessed on
   c-extensions.
   Close 1466

 * Fix a false positive ``useless-super-delegation`` message when
   parameters default values are different from those used in the base class.
   Close 1085

 * Disabling 'wrong-import-order', 'wrong-import-position', or
   'ungrouped-imports' for a single line now prevents that line from
   triggering violations on subsequent lines.

   Close 1336

 * Added a new Python check for inconsistent return statements inside method or function.
   Close 1267

 * Fix ``superfluous-parens`` false positive related to handling logical statements
   involving ``in`` operator.

   Close 574

 * ``function-redefined`` message is no longer emitted for functions and
   methods which names matches dummy variable name regular expression.
   Close 1369

 * Fix ``missing-param-doc`` and ``missing-type-doc`` false positives when
   mixing ``Args`` and ``Keyword Args`` in Google docstring.
   Close 1409

  * Fix ``missing-docstring`` false negatives when modules, classes, or methods
  consist of compound statements that exceed the ``docstring-min-length``

 * Fix ``useless-else-on-loop`` false positives when break statements are
   deeply nested inside loop.
   Close 1661

 * Fix no ``wrong-import-order`` message emitted on ordering of first and third party
   libraries. With this fix, pylint distinguishes third and first party
   modules when checking import order.
   Close 1702

 * Fix ``pylint disable=fixme`` directives ignored for comments following the
   last statement in a file.
   Close 1681

 * Fix ``line-too-long`` message deactivated by wrong disable directive.
   The directive ``disable=fixme`` doesn't deactivate anymore the emission
   of ``line-too-long`` message for long commented lines.
   Close 1741

 * If the rcfile specified on the command line doesn't exist, then an
   IOError exception is raised.
   Close 1747

 * Fix the wrong scope of the ``disable=`` directive after a commented line.
   For example when a ``disable=line-too-long`` directive is at the end of
   a long commented line, it no longer disables the emission of ``line-too-long``
   message for lines that follow.
   Close 1742
