Update cpplint.py to #387:
387 - Allow lint warnings on the next line to be suppressed with NOLINTNEXTLINE.
386 - Fixed false positive for strcat and strcpy.
385 - Fixed false positive for bitwise and on last line of a multi-line
384 - Remove unused deprecated testing/base/googletest.h header.
383 - Fixed false positive for bitwise and on last line of a multi-line
initializer list that ends with closing brace on the same line.
382 - Allow header guard warning to be silenced with
"// NOLINT(build/header_guard)" comment.
381 - Removed check for spaces between "//" and "TODO".
380 - Fix typo: Redudnant -> Redundant
379 - Added check for redundant "virtual" and "override" function-specifier.
378 - Updated missing "explicit" message to match style guide wording
377 - Add cpplint check to prevent .cc file inclusions from other packages.
These are generally bad and we should prevent regressions like this until
proper BUILD layering checks are in place.
376 - Silence missing braces warning for conditional statements inside lambdas.
375 - Warn about multi-arg constructors being explicit only at highest severity
level.
374 - Warn about non-single-argument constructors marked explicit.
373 - Exclude 'case' from function spacing check.
372 - Exclude third party headers such as Python.h from these checks:
371 - Fixed false positive for function pointer parameters followed by other
parameters.
370 - Allow RValue reference for default inline constructor.
369 - Fixed false positive for array of references and operator,().
368 - Silence named parameter warning for macros.
367 - Fixed false positive for duplicate header warning across preprocessor
boundaries.
366 - Allow rvalue references for constructors and assignment operator.
365 - Stop handling DISALLOW_EVIL_CONSTRUCTORS in cpplint.py,
since it's going away.
364 - Fixed false positive for member function in nested classes.
363 - Namespace indentation for cpplint. The C++ style guide enforced that items
within a namespace do not receive an extra level of indentation.
362 - Fixed false positive for multi-line member functions returning strings.
361 - Do not suggest replacement CHECK macros if custom error messages are used.
360 - Silence nonconst reference warning for multiline derived functions.
359 - Silence non-const reference warnings for derived functions.
358 - Added link to developer guide.
357 - Remove the partial ban on std::move and related features. More general
356 - Fixed false positive for << inside macros.
355 - Make _NestingState class public.
354 - Fixed false positive for multiline function templates.
353 - Fixed false positive for lambda capture.
352 - Silence RValue reference warnings that are enclosed in a
351 - Do not warn on CR-LF lines if all input lines are uniformly CR-LF.
350 - Tweaked the error messages for static mutex with default constructors.
349 - Fixed false positive for unnamed parameters in macros.
348 - Recognize &&... as RValue references.
347 - Use alternative error message for including <ostream>.
346 - Fixed false positive for function style template argument.
345 - Fixed false positive for braced constructor call inside brackets.
344 - Minor spelling and grammar fix.
343 - Fixed false positive for non-const reference check inside constructor
342 - Fixed cases where rvalue references are not identified correctly:
341 - Check that third party header files have some header guard, but do not
340 - Don't check header guards in third party files.
339 - Instead of treating thread annotations as macro function calls, skip over
them in parsing function signatures. This silences false positives for
lambdas with thread annotations.
338 - Fixed false positive for deprecated cast where return type of function
337 - Fixed false positive for alias-declarations of function pointers.
336 - Improved error message for taking address of something dereferenced
335 - Added support for C++14 digit separators.
334 - Silence long line warnings for JNI.
333 - Fixed false positive for constructor calls for rand{} being
332 - Elide C++11 raw strings as an empty quoted string instead of
331 - Split up long functions in cpplint.py and cpplint_unittest.py
330 - Fixed false positive for missing space check around "using operator;"
329 - Fixed false positive for indent check around multi-line raw strings.
