Summary:
The `ArcanistXHPASTLinter` class is becoming quite bloated. This diff separates the class into one-class-per-rule, which makes everything much more modular. One downside to this decoupling is that code reuse between linter rules is much more difficult, although this only affects a very small number of linter rules.
There is still some further work that could be done here, but I defer this until a later diff:
- Rewrite `ArcanistPhutilXHPASTLinter` using `ArcanistXHPASTLinterRule`.
- Change the unit tests so that they are truly only testing a single linter rule.
- Maybe improve the way in which linter configuration options are handled.
- Make it easier to keep track of the linter rule IDs (see T6859).

Summary:
Removes the deprecated method of configuring linters (via the `.arcconfig` file). There is one main caveat here:
- There is currently no convenient method by which to change the path for an external linter (T5057). This means that there is no direct replacement for the deprecated `lint.ruby.prefix` configuration. The workaround is to symlink these binaries into `arcanist/externals/bin`.

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`.
