libXft got a symbol cleanup for 2.1.9, and many symbols were hidden, including
XftNameUnparse. It was later decided that XftNameUnparse should still be
exported, since many applications depend on it. It was re-exported for 2.1.10,
but was never properly applied to the git tree, so when 2.1.11 was released, the
symbol was once again hidden.
Following is a patch to re-export the symbol. I'm not sure what else is missing
from libXft's git.
