Several changes:
* Soft-Deprecate Buffer() constructors
* Add `Buffer.from()`, `Buffer.alloc()`, and `Buffer.allocUnsafe()`
* Add `--zero-fill-buffers` command line option
* Add byteOffset and length to `new Buffer(arrayBuffer)` constructor
* buffer.fill('') previously had no effect, now zero-fills
* Update the docs

// this test only fails with CentOS 6.3 using kernel version 2.6.32

// On other linuxes and darwin, the `read` call gets an ECONNRESET in
|
|
// that case. On sunos, the `write` call fails with EPIPE.

|
|
// However, old CentOS will occasionally send an EOF instead of a
|
|
// ECONNRESET or EPIPE when the client has been destroyed abruptly.

|
|
// Make sure we don't keep trying to write or read more in that case.
