test: enable linting for tests Enable linting for the test directory. A number of changes was made so all tests conform the current rules used by lib and src directories. The only exception for tests is that unreachable (dead) code is allowed. test-fs-non-number-arguments-throw had to be excluded from the changes because of a weird issue on Windows CI.

Deprecate string interface for fs.write() This patch makes buffers the preferred input for fs.write() and fs.writeSync(). The old string interface is still supported by converting strings to buffers dynamically. This allows to remove the C++ code for string handling which is also part of this patch. 15 years ago
test: only refresh tmpDir for tests that need it Expose `common.refreshTmpDir()` and only call it for tests that use common.tmpDir or common.PIPE. A positive side effect is the removal of a code smell where child processes were detected by the presence of `.send()`. Now each process can decide for itself if it needs to refresh tmpDir.

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 PR-URL: https://github.com/nodejs/node/pull/4682 Reviewed-By: Сковорода Никита Андреевич <chalkerx@gmail.com> Reviewed-By: Stephen Belanger <admin@stephenbelanger.com> 9 years ago			`written = fs.writeSync(fd, Buffer.from(bar), 0, Buffer.byteLength(bar));`
