Add new user mode option -ignore-environment
An empty environment is sometimes useful in user mode. The new option provides it for linux-user and bsd-user (darwin-user still has no environment related options). The patch also adds the documentation for other environment related options. Signed-off-by: Stefan Weil <weil@mail.berlios.de>
