This backports the new `Buffer.alloc()`, `Buffer.allocUnsafe()`, `Buffer.from()`, and `Buffer.allocUnsafeSlow()` APIs for v4. Some backported tests are disabled, but those are not related to the new API. Note that `Buffer.from(arrayBuffer[, byteOffset [, length]])` is not supported in v4.x, only `Buffer.from(arrayBuffer)` is.
