[util] Move compatibility functions out of util
utils is large enough without these compatibility functions. Everything that is present in newer versions of Python (i.e. with dev Python it's just an import) goes into compat.py . Everything else (i.e. youtube-dl-specific helpers) goes into utils.py .
