fddbcab0e7 Mostly don't require original QPDF for copyForeignObject (fixes #219)
The original QPDF is only required now when the source
QPDFObjectHandle is a stream that gets its stream data from a
QPDFObjectHandle::StreamDataProvider.

fbbb0ee016 Make a static version of QPDF::pipeStreamData
This is in preparation of being able to pipe a stream's data without
keeping a copy of its containing qpdf object.

6f3b76b6c1 Fix image-streams.pdf in test suite
Some of the images were supposed to have no filter, but somewhere
along the line, they ended up with /FlateDecode, most likely because
qpdf rewrote the file without having --compress-streams=n specified.
If this error is repeated, it will cause a test failure.

837dcf8fc2 Don't call assert while checking linearization data (fixes #209, #231)
Instead of calling assert for problems found during checking
linearization data, throw an exception which is later caught and
issued as an error. Ideally we would handle errors more robustly, but
this is still a significant improvement.

a01359189b Fix dangling references (fixes #240)
On certain operations, such as iterating through all objects and
adding new indirect objects, walk through the entire object structure
and explicitly resolve any indirect references to non-existent
objects. That prevents new objects from springing into existence and
causing the previously dangling references to point to them.

f78ea057ca Switch annotation flattening to use the form xobjects
Instead of directly putting the contents of the annotation appearance
streams into the page's content stream, add commands to render the
form xobjects directly. This is a more robust way to do it than the
original solution as it works properly with patterns and avoids
problems with resource name clashes between the pages and the form
xobjects.

3b8ce4f12a Annotation flattening including form fields
Flatten annotations by integrating their appearance streams into the
content stream of the containing page. In the case of form fields,
only flatten if /NeedAppearance is false (or equivalently absent). If
flattening form fields, also remove /AcroForm from the document
catalog.

3440ea7d3c JSON::serialize -> unparse
Unparse is admittedly strange, but I'd rather be strange and
consistent, and everything else in the qpdf library uses unparse to
serialize. (If you're reading this, the convention of using "unparse"
comes from the "clu" programming language.)
