tools: move eslint from tools to tools/node_modules

This is required because we need to add the babel-eslint dependency
and it has to be able to resolve "eslint".
babel-eslint is required to support future ES features such as async
iterators and import.meta.

+# parse-entities [![Build Status][build-badge]][build-status] [![Coverage Status][coverage-badge]][coverage-status]
+
+Parse HTML character references: fast, spec-compliant, positional
+information.
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install parse-entities
+```
+
+## Usage
+
+```js
+var decode = require('parse-entities');
+
+decode('alpha &amp bravo');
+//=> alpha & bravo
+
+decode('charlie &copycat; delta');
+//=> charlie ©cat; delta
+
+decode('echo © foxtrot ≠ golf 𝌆 hotel');
+//=> echo © foxtrot ≠ golf 𝌆 hotel
+```
+
+## API
+
+## `parseEntities(value[, options])`
+
+###### `options`
+
+*   `additional` (`string`, optional, default: `''`)
+    — Additional character to accept when following an ampersand (without
+    error)
+*   `attribute` (`boolean`, optional, default: `false`)
+    — Whether to parse `value` as an attribute value
+*   `nonTerminated` (`boolean`, default: `true`)
+    — Whether to allow non-terminated entities, such as `&copycat` to
+    `©cat`.  This behaviour is spec-compliant but can lead to unexpected
+    results
+*   `warning` ([`Function`][warning], optional)
+    — Error handler
+*   `text` ([`Function`][text], optional)
+    — Text handler
+*   `reference` ([`Function`][reference],
+    optional) — Reference handler
+*   `warningContext` (`'*'`, optional)
+    — Context used when invoking `warning`
+*   `textContext` (`'*'`, optional)
+    — Context used when invoking `text`
+*   `referenceContext` (`'*'`, optional)
+    — Context used when invoking `reference`
+*   `position` (`Location` or `Position`, optional)
+    — Starting `position` of `value`, useful when dealing with values
+    nested in some sort of syntax tree.  The default is:
+
+    ```json
+    {
+      "start": {
+        "line": 1,
+        "column": 1,
+        "offset": 0
+      },
+      "indent": []
+    }
+    ```
+
+###### Returns
+
+`string` — Decoded `value`.
+
+### `function warning(reason, position, code)`
+
+Error handler.
+
+###### Context
+
+`this` refers to `warningContext` when given to `parseEntities`.
+
+###### Parameters
+
+*   `reason` (`string`)
+    — Reason (human-readable) for triggering a parse error
+*   `position` (`Position`)
+    — Place at which the parse error occurred
+*   `code` (`number`)
+    — Identifier of reason for triggering a parse error
+
+The following codes are used:
+
+| Code | Example            | Note                                          |
+| ---- | ------------------ | --------------------------------------------- |
+| `1`  | `foo &amp bar`     | Missing semicolon (named)                     |
+| `2`  | `foo &#123 bar`    | Missing semicolon (numeric)                   |
+| `3`  | `Foo &bar baz`     | Ampersand did not start a reference           |
+| `4`  | `Foo &#`           | Empty reference                               |
+| `5`  | `Foo &bar; baz`    | Unknown entity                                |
+| `6`  | `Foo € baz`   | [Disallowed reference][invalid]               |
+| `7`  | `Foo � baz` | Prohibited: outside permissible unicode range |
+
