This commit introduces an INIT macro to file system functions on
Windows, similar to the one used on Unix platforms. The macro
checks for NULL requests, and returns UV_EINVAL in such
scenarios. This commit also adds support for passing NULL to
uv_fs_req_cleanup(). In this scenario, the function is a
no-op.
