Setup testing XFA using .in fileschromium/3355chromium/3354

This adds a number of {{}} style tags to the .in format that allow the
fix-up script to inject XFA related boilerplate into the PDF, instead of
having the .in file replicate this.

A simple example XFA .in file, called xfa_example.in has been added as a
template for future files to follow.

Finally a run_xfa_tests.py has been added for executing all of the tests
in testing/resources/xfa, which from what I can tell are not executed any
other way. All of the existing PDFs in that directory are currently
suppressed.

 There are several places in a PDF file where byte-offsets are required. This
 script replaces {{name}}-style variables in the input with calculated results
 
-  {{header}}     - expands to the header comment required for PDF files.
-  {{xref}}       - expands to a generated xref table, noting the offset.
-  {{trailer}}    - expands to a standard trailer with "1 0 R" as the /Root.
-  {{startxref}   - expands to a startxref directive followed by correct offset.
