Jay Berkenbilt bedf35d6a5 Bug fix: avoid extraneous pipeline finish calls with multiple contents 
Avoid calling finish() multiple times on the pipeline passed to
pipeContentStreams. This commit also fixes a bug in which qpdf was not
exiting with the proper exit status if warnings found while splitting
pages; this was exposed by a test case that changed.

Jay Berkenbilt a139d2b36d Add several methods for working with form XObjects (fixes #436) 
Make some more methods in QPDFPageObjectHelper work with form
XObjects, provide forEach methods to walk through nested form
XObjects, possibly recursively. This should make it easier to work
with form XObjects from user code.
