Summary:
The `ArcanistXHPASTLinter::LINT_TOSTRING_EXCEPTION` linter rule was introduced in D12854, but fails for the following:
- Interfaces which declare the `__toString()` method.
- Classes which mark the `__toString()` method as `abstract`.
Test Plan: Added test cases.

Summary:
See http://phpsadness.com/sad/39. Declaring a function named `__lambda_func` prevents the `create_function` function from working. This is because `create_function` eval-declares the function `__lambda_func`, then modifies the symbol table so that the function is instead named `"\0lambda_".(++$i)`, and returns that name.
NOTE: Personally, I don't think that anyone should use `create_function`. However, despite this, I think it is reasonable that no function is named `__lambda_func` in case some external library relies on `create_function`.
Test Plan: Added test case.

Summary: Currently the error message from `ArcanistXHPASTLinter::LINT_FORMATTED_STRING` is slightly wrong, mentioning `xsprintf` instead of the actual `sprintf`-style function which was used. This diff changes the error message to be more correct.
Test Plan: Linted a file containing `sprintf('%s')` and saw a reasonable lint message.

```

Summary: Add a linter rule to advise against the use of hardcoded class names. Hardcoded class names make the code harder to refactor and it is generally preferable to use the `__CLASS__` magic constant instead.

According to the [[http://php.net/manual/en/language.oop5.visibility.php#language.oop5.visiblity-methods | PHP documentation]], methods declared without any explicit visibility keyword are defined as public.
