vlc | branch: master | Rémi Denis-Courmont <remi at remlab.net> | Fri Jul  9 17:50:50 2010 +0300| [fd907c9abaa6304442ced84809bdb53600c922ca] | committer: Rémi Denis-Courmont 

Add var_InheritAddress()

Returns NULL if the variable cannot be inherited - pointers can never
be found in the configuration.
