[tex-live] Patch to pdfobj.c

[Simon Cozens]

Hi!

I'm never sure who to contact about dvipdfm-x and associated code, but 
here is a patch which allows the PDF functions to be used more than once 
in an application. Nothing reset the byte counters, meaning that when 
the xref tables were written for PDFs after the first one, the numbers 
would be garbage:
