This adds a couple of helper functions for working within Android: - in_android(): Crude test that uses getenv() to see if an Android- specific environment variable is defined. - android_tmpdir_path(): Android doesn't have the usual locations for temporary file storage such as /tmp or even /var/run/locks. And to make matters worse, there isn't even a standard location for temporary files so it must be determined at run time. This will be used in a follow-up patch.
