Check for duplicate open fonts

When loading multiple PDFs the font streams are often copies of fonts kept
alive in the caches. By keeping a list of open fonts faces, we can scan for
duplicates - the number of open faces should remain small, so a simple list is
sufficient - and return a reference to the existing cached font instead of
creating a new FT_Face.

As an example, this reduces the RSS of the Poppler converter in the Cairo test
suite from over 900MiB to just 90MiB.
