Bug 706316: Improve pdfi/pdfwrite font recognition
Originally, pdfi was extremely conservative in its font creation, ensuring
every font/CIDFont instance has a unique XUID, that ensures we don't have
clashes when a font stream in a PDF is used by multiple font objects with
differing encodings, widths arrays etc...
A side effect of that was that pdfwrite couldn't consolidate instances of fonts
loaded from file (which, unlike embedded subsets, it can do safely).
For fonts loaded from disk, we now skip the pseudo-XUID creation, allowing
pdfwrite to make its own decisions about compatible font instances.
