buffer: add .from(), .alloc() and .allocUnsafe()

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

buffer: faster case for create Buffer from new Buffer(0)

When create Buffer from a Buffer will copy data
from old to new even though length is zero.

This patch can improve edge case 4x faster.
following is benchmark results.
