[Fontconfig] Threadsafe fontconfig

[Behdad Esfahbod]

Akira,

I finally managed to finish the threadsafety work in Pango.  With that, and
fontconfig master, I managed to render thousands of images of text from
thousands of threads without any crash so far.  As such, GNOME people are
really interested in getting this in a release.  Do you think you can make a
release next week?

It doesn't have to be marked a stable release.  Just a release such that Pango
can require it, and packages can package it.

Cheers,
