Convert an arbitrary string into a valid version string.
Can still raise an ``InvalidVersion`` exception.
To avoid exceptions use ``best_effort_version``.
>>> safe_version("1988 12 25")
'1988.12.25'
>>> safe_version("v0.2.1")
'0.2.1'
>>> safe_version("v0.2?beta")
'0.2b0'
>>> safe_version("v0.2 beta")
'0.2b0'
>>> safe_version("ubuntu lts")
Traceback (most recent call last):
