Subject: [PATCH] assert, tools: enforce strict (not)equal in eslint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extend no-restricted-properties to catch use of assert.equal() and
assert.notEqual() and require assert.strictEqual() or
assert.notStrictEqual() instead.

Also update the eslint-ignore in lib/assert.js to avoid
assert.equal/notEqual linter errors in their definitions.
