Jay Berkenbilt a372a988fd Switch build from docbook manual to sphinx 
Also remove linearization from qpdf-manual.pdf. It's a small file, and
removing the dependency on the qpdf executable significantly shortens
build times.

Jay Berkenbilt 9a5d16a403 Prepare for docbook -> rst: replace SGML entitles 
We were using SGML entities for various non-ASCII characters so they
could convert properly for both HTML and print, but this is no longer
necessary as we move from docbook to RST, so just replace them. Note
that the conversions done by sphinx automatically handle "smart
quotes", so it works to just use regular quotes in place of “
and ”.

Jay Berkenbilt f721fed9d6 doc: Replace Gajic with Gajić (finally) 
With docbook, this was not converted properly in the PDF version, but
since we are moving out of docbook, we can just put the Unicode
character in the source.

Jay Berkenbilt e5c2bd8b14 TODO: doc conversion notes 
Make a list of things that need to be done while converting docbook to
sphinx/rst.

Jay Berkenbilt 8acb79fc5e Remove notes on safe QPDFObjectHandle -- not worth doing 
The impact on the code would be extremely high, and using it would
clutter the code greatly because it would break chaining like
a.getKey("/B").getKey("/C"). There are better ways to deal with the
issue.

Jay Berkenbilt a77f58142d Remove some assertions that are not necessarily true (fixes #514) 
Operations that add the same object to multiple places in the pages
tree are throwing exceptions and then later causing assertion
failures. The assert calls shouldn't be there.

Jay Berkenbilt e17585c2d2 Remove unreferenced: ignore names that are not Fonts or XObjects 
Converted ResourceFinder to ParserCallbacks so we can better detect
the name that precedes various operators and use the operators to sort
the names into resource types. This enables us to be smarter about
detecting unreferenced resources in pages and also sets the stage for
reconciling differences in /DR across documents.

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 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.
