providers. Length should not be checked or recorded if the provider
says it failed to generate the data.

Jay Berkenbilt e076c9bf08 Remove erroneous handling of /EFF for stream decryption 
I thought /EFF was supposed to be used as a default for decrypting
embedded file streams, but actually it's supposed to be advice to a
conforming writer about handling new ones. This makes sense since the
findAttachmentStreams code, which is not actually needed, was never
right.

Jay Berkenbilt faa2e3ddfd Handle older PDFs whose form XObjects inherit resources (fixes #494) 
When removing unreferenced resources, notice if a page (recursively)

such resources as referenced by the page.

Jay Berkenbilt 8ed3e8c79b NNTree: rework iterators to be more memory efficient 
Keep a std::pair internal to the iterators so that operator* can
return a reference and operator-> can work, and each can work without
copying pairs of objects around.

Jay Berkenbilt 4a1cce0a47 Reimplement name and number tree object helpers 
Create a computationally and memory efficient implementation of name
and number trees that does binary searches as intended by the data
structure rather than loading into a map, which can use a great deal
of memory and can be very slow.

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.

Masamichi Hosoda 5a842792b6 Parse Contents in signature dictionary without encryption 
Various PDF digital signing tools do not encrypt /Contents value in
signature dictionary. Adobe Acrobat Reader DC can handle a PDF with
the /Contents value not encrypted.

Write Contents in signature dictionary without encryption

Tests ensure that string /Contents are not handled specially when not
found in sig dicts.

representation when ByteRange is specified.

This commit makes QPDF always uses hexadecimal strings representation
instead of literal strings for it.
