Set the default maxBuffer size to 204,800 bytes for execSync,
execFileSync, and spawnSync.
APIs that return the child output as a string should have non-infinite
defaults for maxBuffer sizes to avoid out-of-memory error conditions. A
non-infinite default used to be the documented behaviour for all
relevant APIs, but the implemented behaviour for execSync, execFileSync
and spawnSync was to have no maxBuffer limits.

The object returned by `child_process.spawnSync()` can have the `status`
property set to `null` if the process terminated due to a signal. We
even test for this in
test/parallel/test-child-process-spawnsync-kill-signal.js.
Update the documentation to reflect this.

On Windows, normalizeSpawnArguments set "/d /s /c" for any shells.
It cause exec and other methods are limited to cmd.exe as a shell.
Powershell and git-bash are often used instead of cmd.exe,
and they can recieve "-c" switch like unix shells.
So normalizeSpawnArguments is changed to set "/d /s /c" for cmd.exe,
and "-c" for others.
